Abstract:
ABSTRACTThe impact of simultaneous anaerobiosis and low temperature on growth parameters, metabolism, and membrane properties ofBacillus cereusATCC 14579 was studied. No growth was observed under anaerobiosis at 12°C. In bioreactors, growth rates and biomass production were drastically reduced by simultaneous anaerobiosis and low temperature (15°C). The two conditions had a synergistic effect on biomass reduction. In anaerobic cultures, fermentative metabolism was modified by low temperature, with a marked reduction in ethanol production leading to a lower ability to produce NAD+. Anaerobiosis reduced unsaturated fatty acids at both low optimal temperatures. In addition, simultaneous anaerobiosis and low temperatures markedly reduced levels of branched-chain fatty acids compared to all other conditions (accounting for 33% of total fatty acids against more 71% for low-temperature aerobiosis, optimal-temperature aerobiosis, and optimal-temperature anaerobiosis). This corresponded to high-melting-temperature lipids and to low-fluidity membranes, as indicated by differential scanning calorimetry, 1,6-diphenyl-1,3,5-hexatriene (DPH) fluorescence anisotropy, and infrared spectroscopy. This is in contrast to requirements for cold adaptation. A link between modification in the synthesis of metabolites of fermentative metabolism and the reduction of branched-chain fatty acids at low temperature under anaerobiosis, through a modification of the oxidizing capacity, is assumed. This link may partly explain the impact of low temperature and anaerobiosis on membrane properties and growth performance.

Abstract The effects of root anaerobiosis on root respiration and leaf conductance (kl) were determined in solution culture experiments. Respiration of feeder roots (<2 mm diameter) in air (21% O2) of Pyrus betulaefolia Bunge, Pyrus calleryana Decne, Pyrus communis L. (‘Old Home’ × ‘Farmingdale 97’) and Cydonia oblonga Mill. ‘Provence BA 29’ was reduced by no more than 50% after 21 days of anaerobiosis. In contrast, root respiration of Prunus persica (L.) Batsch ‘Lovell’ was reduced by 80% with anaerobiosis, whereas that of Salix discolor Muhl. increased. Reductions in kl with anaerobiosis generally were more pronounced than reduction in root respiration when measured in air. Respiration rates of aerobically or anaerobically treated pear roots were inhibited by 25% to 50% when incubated in 0.5% O2 compared to rates in air. More work is required in order to delineate the relationship of root respiration and kl with anaerobiosis.

Abstract:
ABSTRACT Lactobacillus sakei is a lactic acid bacterium belonging to the natural flora of meat products. It constitutes the main flora of vacuum-packed meat and is largely used in western Europe as a starter for the manufacturing of fermented sausages. This species is able to grow both under aerobiosis and anaerobiosis. In many technological processes involving it, oxygen is scarce. The aim of this study was to identify the major proteins affected by growth under anaerobiosis. Using two-dimensional electrophoresis, we showed that one spot was 10-fold overexpressed when cells were grown under anaerobiosis. By N-terminal sequencing it was identified as a peptidase (PepR), and the pepR gene was cloned. Northern analysis revealed that pepR was expressed as a single 1.27-kb transcript induced under anaerobiosis. A mutant was constructed by single crossover in the pepR gene, and its growth and survival were not affected by anaerobiosis.

Abstract:
Biofilm-forming bacteria can protect mild (unalloyed) steel from corrosion. Mild steel coupons incubated with Rhodoccocus sp. strain C125 and Pseudomonas putida mt2 in an aerobic phosphate-buffered medium containing benzoate as carbon and energy source, underwent a surface reaction leading to the formation of a corrosion-inhibiting vivianite layer [Fe3(PO4)2]. Electrochemical potential (E) measurements allowed us to follow the buildup of the vivianite cover. The presence of sufficient metabolically active bacteria at the steel surface resulted in an E decrease to -510 mV, the potential of free iron, and a continuous release of ferrous iron. Part of the dissolved iron precipitated as vivianite in a compact layer of two to three microns in thickness. This layer prevented corrosion of mild steel for over two weeks, even in a highly corrosive medium. A concentration of 20 mM phosphate in the medium was found to be a prerequisite for the formation of the vivianite layer.

Abstract:
Proton-equivalent ion transfer processes between animals and ambient water were determined under normoxic control conditions during anaerobiosis and the subsequent recovery period in the marine worm Sipunculus nudus L. During anaerobiosis and recovery, transepithelial H+-equivalent ion transfer was generally correlated with changes in extracellular pH, with some disparities in ‘spring’ animals. The typical initial alkalosis induced by phosphagen cleavage during early anaerobiosis was reflected by a loss of basic equivalents. The acidosis, which developed later, reflecting production of acidic metabolic intermediates, resulted in a relatively small net extrusion of protons into the water. The coelomic acidosis during recovery was greatly exaggerated by the release of protons during phosphagen repletion and by the considerable elevation of Pco2 after normoxia had been reattained. The acidosis stimulated the net release of H+ to the water at a rate several times higher than that during anaerobiosis. The efficient transfer of protons from the body fluids to the environmental water during recovery facilitated normalization of coelomic pH, long before protons dissociated from the large amounts of organic acids produced as anaerobic intermediates could be removed from the body fluids by metabolism. Although the transfer of net H+ equivalents to the water coincided with coelomic acidosis, the rates of transfer during different periods of the experiment were primarily correlated with overall metabolic rate. Low net proton transfer rates associated with anaerobiosis were not sufficient to maintain acid-base parameters typical for normoxia, whereas re-establishment of aerobic conditions facilitated a greatly increased transepithelial H+ transfer rate. These data suggest that the transfer capacity of the energy-consuming translocation mechanism may primarily be determined by the rate of metabolic turnover and, accordingly, by theamount of available energy.

Abstract:
Our aim was to develop an Emmental juice-like medium (EJLM) for the growth of propionibacteria. Cheese juices were extracted by pressing three different Emmental cheeses before entering the warm room (i.e. before propionic fermentation) and their composition was determined. They contained (g/kg) lactate 34·6–36·9, protein 23·8–29·6, NaCl 15–23, Ca 5·9–7·3 and no residual sugar, and had a pH of 5·4. In order to simulate this composition, EJLM was constituted from the microfiltrate of a milk, enriched in native casein and fermented by a Lactobacillus helveticus strain until lactose exhaustion. PO43−, K+, Mg2+, Ca2+ and Cl− were added to reach a mineral balance and an ionic strength close to those of juice. The main difference was the nitrogen content: that of juice was ∼3·5 times that of EJLM. Four Propionibacterium freudenreichii strains grew with similar growth rates in EJLM and in juice at 24°C in anaerobiosis and reached >3×109 cfu/ml. Using EJLM, Prop. freudenreichii TL 173 grew at pH 5·4 or 6·0, at 24 or 30°C, in semi-anaerobiosis (static culture) or anaerobiosis (CO2 atmosphere), showing a synergic inhibition of growth at low pH and temperature and in semi-anaerobiosis. EJLM provided a way to study propionibacteria in an environment similar to that in Emmental cheese.

Abstract:
Recovery from 24 h of anaerobiosis was investigated in Sipunculus nudus L. by monitoring changes in the concentrations of anaerobic metabolites in the musculature and in the coelomic plasma. The metabolic events in animals collected during March and October were compared. Anaerobiosis led to an increase of succinate, propionate and acetate in the muscle tissues and the coelomic plasma. Strombine, octopine and alanine (predominantly l- rather than d-alanine) accumulated in the musculature, whereas aspartate and phospho-l-arginine levels decreased. A higher metabolic rate was observed during anaerobiosis in October than in March animals, as indicated by the higher amounts of strombine, octopine and acetate formed. An increase in metabolic rate appears to entail an increase of flux through the Embden-Meyerhof pathway which favours the accumulation of direct derivatives of pyruvate. During recovery, regeneration of phospho-l-arginine occurred during the first 3 h, whereas disposal of succinate, octopine and propionate was observed during the entire 24-h period of recovery. Strombine, alanine and, to a lesser extent, acetate contents remained elevated. The concentration of d-alanine approached that of Lalanine during recovery, indicating the activity of alanine racemase. Malate levels increased transiently, possibly linked to the repletion of the aspartate pool. In October animals, strombine seemed to accumulate transiently during initial recovery, indicating that the energy demand was not met by aerobic metabolism alone. In contrast to the situation in March animals, however, anaerobic glycolysis during recovery obviously becomes important only when the metabolic rate during anaerobiosis was high enough.

Abstract:
ABSTRACT Two bacterial species with different metabolic features, namely, Pseudomonas aeruginosa and Lactococcus lactis, were used as a comparative experimental model to investigate the antimicrobial target and mechanism of transferrins. In anaerobiosis, P. aeruginosa cells were not susceptible to lactoferrin (hLf) or transferrin (hTf). In aerobiosis, the cells were susceptible but O2 consumption was not modified, indicating that components of the electron transport chain (ETC) were not targeted. However, the respiratory chain inhibitor piericidin A significantly reduced the killing activity of both proteins. Moreover, 2,6-dichlorophenolindophenol (DCIP), a reducing agent that accepts electrons from the ETC coupled to H+ extrusion, made P. aeruginosa susceptible to hLf and hTf in anaerobiosis. These results indicated that active cooperation of the cell was indispensable for the antimicrobial effect. For L. lactis cells lacking an ETC, the absence of a detectable transmembrane electrical potential in hLf-treated cells suggested a loss of H+-ATPase activity. Furthermore, the inhibition of ATPase activity and H+ translocation (inverted membrane vesicles) provided direct evidence of the ability of hLf to inhibit H+-ATPase in L. lactis. Based on these data, we propose that hLf and hTf also inhibit the H+-ATPase of respiring P. aeruginosa cells. Such inhibition thereby interferes with reentry of H+ from the periplasmic space to the cytoplasm, resulting in perturbation of intracellular pH and the transmembrane proton gradient. Consistent with this hypothesis, periplasmic H+ accumulation was prevented by anaerobiosis or by piericidin A or was induced by DCIP in anaerobiosis. Collectively, these results indicate that transferrins target H+-ATPase and interfere with H+ translocation, yielding a lethal effect in vitro.

Abstract:
Abstract The effect of anaerobiosis, imposed during germination of ‘Calypso’ cucumber (Cucumis sativas L.) seeds, was studied. Anaerobic conditions inhibited reserve mobilization from the cotyledons and dry weight gain by the embryonic axis. Within the embryonic axis, lipid degradation was stopped and use of all readily metabolizable carbohydrate reserves was strongly stimulated. By 48 hr of exposure to an anaerobic environment, the axis was nearly depleted of endogenous carbohydrate reserves. Aerobically germinating seeds accumulated a massive concentration of hexose sugars within the axis during the same time period. Thus, growth inhibition within cucumber seeds during anaerobiosis may result in part from carbohydrate deprivation of the embryonic axis.

Introduction: This study aimed to prove whether the palladium catalyst affects the dew formation time in the anaerobic cover and whether anaerobiosis can be achieved without a palladium catalyst. Materials and Methods: This research is a laboratory experimental study with a non-randomized control group design. In this study, replication was carried out. The amount of replication used is 10. The palladium catalyst was used in 10 experiments, whereas it was not used in ten other experiments. Results: The growths of Pseudomonas aeruginosa, Clostridium tetani, and Bacteroides fragilis were observed after 48-hour incubation. The time of appearance of water condensate was observed until 24-hour incubation. The time of appearance of water condensate in the palladium-contained anaerobic jar varied between 1.37 minutes and 3.33 minutes. On the other hand, water condensate did not appear in the without-palladium anaerobic jar. No growth of Pseudomonas aeruginosa was observed in the palladium-contained anaerobic jar; on the contrary, there were ten growths in the anaerobic jar without palladium. Eight growths of Clostridium tetani were observed in the palladium-contained anaerobic jar, whereas there was no growth without palladium. No growth of Bacteroides fragilis was observed in the without-palladium anaerobic jar, whereas seven growths were observed in the anaerobic jar containing palladium. The time of appearance of water condensate in the palladium-contained anaerobic jar was different from that in the anaerobic jar without palladium. Significant differences (p < 0,01) in anaerobiosis creation between the palladium-contained anaerobic jar and the without-palladium anaerobic jar were also clearly observed.

Abstract:
ABSTRACT The cupA gene cluster of Pseudomonas aeruginosa encodes components and assembly factors of a putative fimbrial structure that enable this opportunistic pathogen to form biofilms on abiotic surfaces. In P. aeruginosa the control of cupA gene expression is complex, with the H-NS-like MvaT protein functioning to repress phase-variable (on/off) expression of the operon. Here we identify four positive regulators of cupA gene expression, including three unusual regulators encoded by the cgrABC genes and Anr, a global regulator of anaerobic gene expression. We show that the cupA genes are expressed in a phase-variable manner under anaerobic conditions and that the cgr genes are essential for this expression. We show further that cgr gene expression is negatively controlled by MvaT and positively controlled by Anr and anaerobiosis. Expression of the cupA genes therefore appears to involve a regulatory cascade in which anaerobiosis, signaled through Anr, stimulates expression of the cgr genes, resulting in a concomitant increase in cupA gene expression. Our findings thus provide mechanistic insight into the regulation of cupA gene expression and identify anaerobiosis as an inducer of phase-variable cupA gene expression, raising the possibility that phase-variable expression of fimbrial genes important for biofilm formation may occur in P. aeruginosa persisting in the largely anaerobic environment of the cystic fibrosis host lung.

Abstract:
In vitro pure-culture studies were conducted to assess growth and sheen formation of groundwater bacteria on M-Endo medium incubated under reduced oxygen concentrations (0, 4, 8, 12, and 16%). Coliform and noncoliform bacteria were isolated from 17 untreated, rural groundwater supplies on M-Endo medium. All 16 coliform isolates tested were capable of sheen formation at oxygen concentrations of 4% or greater, yet some of these same isolates (Enterobacter aerogenes, Enterobacter cloacae, and Hafnia alvei) were either unable to grow or failed to produce a metallic sheen when incubated under strict anaerobiosis. Approximately 70% of the 21 noncoliform isolates examined exhibited growth inhibition at oxygen concentrations of 8% or less. The growth of a false-positive coliform isolate of Serratia fonticola was inhibited when incubated under reduced oxygen concentrations of 16% or less. Our findings suggest that the selectivity of M-Endo medium, and resultant inhibition of noncoliforms and false-positive coliforms, is enhanced by incubation in the absence of oxygen. However, the failure of strict anaerobiosis to permit detection of total coliforms such as Hafnia and Enterobacter spp. may compromise the reliability of this technique for evaluating the sanitary quality of some waters. On the other hand, oxygen concentrations of 4, 8, 12, and 16% permitted adequate sheen development of all coliforms tested while inhibiting some noncoliforms. Key words: coliforms, anaerobiosis, groundwater, sheen formation.

Abstract:
ABSTRACTPseudomonas aeruginosaundergoes cell elongation and forms robust biofilms during anaerobic respiratory growth using nitrate (NO3−) as an alternative electron acceptor. Understanding the mechanism of cell shape change induced upon anaerobiosis is crucial to the development of effective treatments againstP. aeruginosabiofilm infection. Here, we uncovered the molecular basis of anaerobiosis-triggered cell elongation and identified vitamin B12to be a molecule that can reinstate defective anaerobic growth ofP. aeruginosa. The ratio of total cellular DNA content to protein content was significantly decreased in the PAO1 strain grown under anaerobic conditions, indicating that DNA replication is impaired during anaerobic growth. Anaerobic growth of PAO1 reached a higher cell density in the presence of vitamin B12, an essential coenzyme of class II ribonucleotide reductase. In addition, cell morphology returned to a normal rod shape and transcription of stress-response genes was downregulated under the same anaerobic growth conditions. These results suggest that vitamin B12, the production of which was suppressed during anaerobic growth, can restore cellular machineries for DNA replication and therefore facilitate better anaerobic growth ofP. aeruginosawith normal cell division. Importantly, biofilm formation was substantially decreased when grown with vitamin B12, further demonstrating that anaerobiosis-induced cell elongation is responsible for robust biofilm formation. Taken together, our data reveal mechanistic details of a morphological change that naturally occurs during anaerobic growth ofP. aeruginosaand illustrates the ability of vitamin B12to modulate the biofilm-forming capacity ofP. aeruginosaunder such condition.

Abstract:
ABSTRACT The OmpD porin is the most abundant outer membrane protein in Salmonella enterica serovar Typhimurium and represents about 1% of total cell protein. Unlike the case with the less abundant OmpC and OmpF porins, the stoichiometry of OmpD in the outer membrane does not change in response to changes in osmolarity. The abundance of OmpD increases in response to anaerobiosis and decreases in response to low pH, conditions encountered by serovar Typhimurium during the infection of its murine host. By constructing an operon fusion of the lacZY genes with the ompD promoter, we show that the abundance of OmpD in the outer membrane is regulated primarily at the level of transcription and is subject to catabolite repression. In response to anaerobiosis, the abundance of OmpD in the outer membrane also appears to be controlled posttranscriptionally by a function dependent on Fnr.

Abstract:
The eukaryotic green alga, Chlamydomonas reinhardtii, produces H2 under anaerobic conditions, in a reaction catalysed by an [FeFe]-hydrogenase. To identify genes that influence H2 production in C. reinhardtii, a library of 6000 colonies on agar plates was screened with sensitive chemochromic H2-sensor films for clones defective in H2 production. Two mutants of particular interest were fully characterized. One mutant, hydEF-1, is unable to assemble an active [FeFe]-hydrogenase. This is the first reported C. reinhardtii mutant that is not capable of producing any H2. The second mutant, sta7-10, is not able to accumulate insoluble starch and has significantly lowered H2-photoproduction rates in comparison with the wild-type. In hydEF-1, anaerobiosis induces transcription of the two reported C. reinhardtii hydrogenase genes, HydA1 and HydA2, indicating a normal transcriptional response to anaerobiosis. In contrast, the transcription of both hydrogenase genes in sta7-10 is significantly attenuated.

Abstract:
The effect of decreased oxygen concentration during incubation of M-Endo medium on detection of coliforms from rural groundwater supplies was examined. Incubation oxygen concentrations of 0 (anaerobic GasPak), 4, 8, and 21% (atmospheric) were examined. Our findings point to several advantages of using anaerobic incubation for the isolation of coliforms: (i) higher verification rates with concomitant decreases in occurrence of false-positive coliforms; (ii) overall reduction in growth of nonsheen colonies; and (iii) reduction in colony size for nonsheen organisms, thereby minimizing crowding effects and facilitating enumeration of coliform colonies. However, these advantages were not sufficient to permit increased recovery of total coliforms as compared with standard aerobic incubation. In addition, the increased frequency of detecting false-negative coliforms during anaerobic incubation is a disadvantage to this method. While detection of total coliforms was reduced under conditions of anaerobiosis, the detection of fecal coliforms and (or) E. coli was not impeded.Key words: coliforms, anaerobiosis, groundwater, sheen formation.

Abstract:
ABSTRACT The capacity of Escherichia coli to adapt its catabolism to prevailing redox conditions resides mainly in three catabolic branch points involving (i) pyruvate formate-lyase (PFL) and the pyruvate dehydrogenase complex (PDHc), (ii) the exclusively fermentative enzymes and those of the Krebs cycle, and (iii) the alternative terminal cytochrome bd and cytochrome bo oxidases. A quantitative analysis of the relative catabolic fluxes through these pathways is presented for steady-state glucose-limited chemostat cultures with controlled oxygen availability ranging from full aerobiosis to complete anaerobiosis. Remarkably, PFL contributed significantly to the catabolic flux under microaerobic conditions and was found to be active simultaneously with PDHc and cytochrome bdoxidase-dependent respiration. The synthesis of PFL and cytochromebd oxidase was found to be maximal in the lower microaerobic range but not in a ΔArcA mutant, and we conclude that the Arc system is more active with respect to regulation of these two positively regulated operons during microaerobiosis than during anaerobiosis.

Abstract:
ABSTRACT We conducted a comprehensive genomic analysis of the temporal response of yeast to anaerobiosis (six generations) and subsequent aerobic recovery (≈2 generations) to reveal metabolic-state (galactose versus glucose)-dependent differences in gene network activity and function. Analysis of variance showed that far fewer genes responded (raw P value of ≤10−8) to the O2 shifts in glucose (1,603 genes) than in galactose (2,388 genes). Gene network analysis reveals that this difference is due largely to the failure of “stress”-activated networks controlled by Msn2/4, Fhl1, MCB, SCB, PAC, and RRPE to transiently respond to the shift to anaerobiosis in glucose as they did in galactose. After ≈1 generation of anaerobiosis, the response was similar in both media, beginning with the deactivation of Hap1 and Hap2/3/4/5 networks involved in mitochondrial functions and the concomitant derepression of Rox1-regulated networks for carbohydrate catabolism and redox regulation and ending (≥2 generations) with the activation of Upc2- and Mot3-regulated networks involved in sterol and cell wall homeostasis. The response to reoxygenation was rapid (<5 min) and similar in both media, dominated by Yap1 networks involved in oxidative stress/redox regulation and the concomitant activation of heme-regulated ones. Our analyses revealed extensive networks of genes subject to combinatorial regulation by both heme-dependent (e.g., Hap1, Hap2/3/4/5, Rox1, Mot3, and Upc2) and heme-independent (e.g., Yap1, Skn7, and Puf3) factors under these conditions. We also uncover novel functions for several cis-regulatory sites and trans-acting factors and define functional regulons involved in the physiological acclimatization to changes in oxygen availability.

Abstract:
ABSTRACT In contrast to previous steady-state analyses of the O2-responsive transcriptome, here we examined the dynamics of the response to short-term anaerobiosis (2 generations) in both catabolite-repressed (glucose) and derepressed (galactose) cells, assessed the specific role that Msn2 and Msn4 play in mediating the response, and identified gene networks using a novel clustering approach. Upon shifting cells to anaerobic conditions in galactose medium, there was an acute (∼10 min) yet transient (<45 min) induction of Msn2- and/or Msn4-regulated genes associated with the remodeling of reserve energy and catabolic pathways during the switch from mixed respiro-fermentative to strictly fermentative growth. Concomitantly, MCB- and SCB-regulated networks associated with the G1/S transition of the cell cycle were transiently down-regulated along with rRNA processing genes containing PAC and RRPE motifs. Remarkably, none of these gene networks were differentially expressed when cells were shifted in glucose, suggesting that a metabolically derived signal arising from the abrupt cessation of respiration, rather than O2 deprivation per se, elicits this “stress response.” By ∼0.2 generation of anaerobiosis in both media, more chronic, heme-dependent effects were observed, including the down-regulation of Hap1-regulated networks, derepression of Rox1-regulated networks, and activation of Upc2-regulated ones. Changes in these networks result in the functional remodeling of the cell wall, sterol and sphingolipid metabolism, and dissimilatory pathways required for long-term anaerobiosis. Overall, this study reveals that the acute withdrawal of oxygen can invoke a metabolic state-dependent “stress response” but that acclimatization to oxygen deprivation is a relatively slow process involving complex changes primarily in heme-regulated gene networks.

Abstract:
Herein we report the use of an environmental multimetal(loid)-resistant strain, MF05, to biosynthesize single- or multi-element nanostructures under anaerobic conditions. Inorganic nanostructure synthesis typically requires methodologies and conditions that are harsh and environmentally hazardous. Thus, green/eco-friendly procedures are desirable, where the use of microorganisms and their extracts as bionanofactories is a reliable strategy. First, MF05 was entirely sequenced and identified as an Escherichia coli-related strain with some genetic differences from the traditional BW25113. Secondly, we compared the CdS nanostructure biosynthesis by whole-cell in a design defined minimal culture medium containing sulfite as the only sulfur source to obtain sulfide reduction from a low-cost chalcogen reactant. Under anaerobic conditions, this process was greatly favored, and irregular CdS (ex. 370 nm; em. 520–530 nm) was obtained. When other chalcogenites were tested (selenite and tellurite), only spherical Se0 and elongated Te0 nanostructures were observed by TEM and analyzed by SEM-EDX. In addition, enzymatic-mediated chalcogenite (sulfite, selenite, and tellurite) reduction was assessed by using MF05 crude extracts in anaerobiosis; similar results for nanostructures were obtained; however Se0 and Te0 formation were more regular in shape and cleaner (with less background). Finally, the in vitro nanostructure biosynthesis was assessed with salts of Ag, Au, Cd, and Li alone or in combination with chalcogenites. Several single or binary nanostructures were detected. Our results showed that MF05 is a versatile anaerobic bionanofactory for different types of inorganic NS. synthesis.
