Abstract:
To date, numerous modified nucleosides in tRNA as well as tRNA modification enzymes have been identified not only in thermophiles but also in mesophiles. Because most modified nucleosides in tRNA from thermophiles are common to those in tRNA from mesophiles, they are considered to work essentially in steps of protein synthesis at high temperatures. At high temperatures, the structure of unmodified tRNA will be disrupted. Therefore, thermophiles must possess strategies to stabilize tRNA structures. To this end, several thermophile-specific modified nucleosides in tRNA have been identified. Other factors such as RNA-binding proteins and polyamines contribute to the stability of tRNA at high temperatures. Thermus thermophilus, which is an extreme-thermophilic eubacterium, can adapt its protein synthesis system in response to temperature changes via the network of modified nucleosides in tRNA and tRNA modification enzymes. Notably, tRNA modification enzymes from thermophiles are very stable. Therefore, they have been utilized for biochemical and structural studies. In the future, thermostable tRNA modification enzymes may be useful as biotechnology tools and may be utilized for medical science.

Abstract:
Synthetic biology applications rely on a well-characterized set of microbial strains, with an established toolbox of molecular biology methods for their genetic manipulation. Since there are no thermophiles with such attributes, most biotechnology and synthetic biology studies use organisms that grow in the mesophilic temperature range. As a result, thermophiles, a heterogenous group of microbes that thrive at high (>50 °C) temperatures, are largely overlooked, with respect to their biotechnological potential, even though they share several favorable traits. Thermophilic bacteria tend to grow at higher rates compared to their mesophilic counterparts, while their growth has lower cooling requirements and is less prone to contamination. Over the last few years, there has been renewed interest in developing tools and methods for thermophile bioengineering. In this perspective, we explain why it is a good idea to invest time and effort into developing a thermophilic synthetic biology direction, which is the state of the art, and why we think that the implementation of a thermophilic synthetic biology platform—a thermochassis—will take synthetic biology to the extremes.

Abstract:
The directed search for extremophilic producers in order to obtain hydrolytic enzymes with increased thermal stability has an unconditional practical potential for use in the food and feed industry to improve the quality of the final product. The aim of the work was to study the ability of collection strains of thermophilic fungi to show α-L-rhamnosidase, α-galactosidase, cellulase, β-mannanase, keratinase and caseinolytic activity. Methods. Micromycetes were grown under submerged conditions in test tubes at 42°C for 8–14 days. Enzymatic activities were studied in the culture liquid supernatant. p-Nitrophenyl-α-D-galactopyranoside, naringin, guar gum galactomannan and Na-carboxymethylcellulose were used as substrates to determine α-galactosidase, α-L-rhamnosidase, β-mannanase and cellulase activities, respectively. Casein and crushed defatted feathers were served as substrates for the determination of proteolytic activity. Results. The enzymatic activity of 50 strains of micromycetes belonging to 17 species was investigated. The studied group showed high activity: 94% of the strains had at least one, 34% – two, 26% – from three to five enzyme activities. The most active keratinase producers were Thielavia terrestris 1920 and 62, Rhizomucor tauricus 1909, Chrysosporium thermophilum 2050, Thermoascus thermophilus 92 and Thermoascus aurantiаcus 2052 (10–26 U/mL). The highest α-L-rhamnosidase activity was observed in T. terrestris 62 (0.35 U/mL), and carboxymethylcellulase activity −in Thermomyces lanuginosus 2046. Six strains showed α-galactosidase (0.05–0.2 U/mL) and four strains − β-mannanase (5–130 U/mL) activity. Conclusions. As a result new strains producing proteolytic and glycolytic enzymes were isolated among thermophilic micromycetes. Soil thermophilic micromycetes can be used as producers of proteolytic and glycolytic enzymes. Of particular interest are the cultures of Acremonium thermophilum 1963, Corynascus thermophilum 2050, C. sepedonium 1899 and 65068, T. thermophilus 1946, which are capable of producing complexes of proteases and glycosidases in the culture liquid. This indicates that these strains are promising for use as destructors in various technologies processing of complex raw materials.

Abstract:
Background: In recent years, various substrates have been tested to increase the sustainable production of biomethane. The effect of these substrates on methanogenesis has been investigated mainly in small volume fermenters and were, for the most part, focused on studying the diversity of mesophilic microorganisms. However, studies of thermophilic communities in large scale operating mesophilic biogas plants do not yet exist. Methods: Microbiological, biochemical, biophysical methods, and statistical analysis were used to track thermophilic communities in mesophilic anaerobic digesters. Results: The diversity of the main thermophile genera in eight biogas plants located in the Czech Republic using different input substrates was investigated. In total, 19 thermophilic genera were detected after 16S rRNA gene sequencing. The highest percentage (40.8%) of thermophiles was found in the Modřice biogas plant where the input substrate was primary sludge and biological sludge (50/50, w/w %). The smallest percentage (1.87%) of thermophiles was found in the Čejč biogas plant with the input substrate being maize silage and liquid pig manure (80/20, w/w %). Conclusions: The composition of the anaerobic consortia in anaerobic digesters is an important factor for the biogas plant operator. The present study can help characterizing the impact of input feeds on the composition of microbial communities in these plants.

Abstract:
Thermophilic cyanobacteria are cosmopolitan and abundant in the thermal environment. Their light-harvesting complexes, phycobilisomes (PBS), are highly important in photosynthesis. To date, there is limited information on the PBS composition of thermophilic cyanobacteria whose habitats are challenging for survival. Herein, genome-based methods were used to investigate the molecular components of PBS in 19 well-described thermophilic cyanobacteria. These cyanobacteria are from the genera Leptolyngbya, Leptothermofonsia, Ocullathermofonsia, Thermoleptolyngbya, Trichothermofonsia, Synechococcus, Thermostichus, and Thermosynechococcus. According to the phycobiliprotein (PBP) composition of the rods, two pigment types are observed in these thermophiles. The amino acid sequence analysis of different PBP subunits suggests several highly conserved cysteine residues in these thermophiles. Certain amino acid contents in the PBP of thermophiles are significantly higher than their mesophilic counterparts, highlighting the potential roles of specific substitutions of amino acid in the adaptive thermostability of light-harvesting complexes in thermophilic cyanobacteria. Genes encoding PBS linker polypeptides vary among the thermophiles. Intriguingly, motifs in linker apcE indicate a photoacclimation of a far-red light by Leptolyngbya JSC-1, Leptothermofonsia E412, and Ocullathermofonsia A174. The composition pattern of phycobilin lyases is consistent among the thermophiles, except for Thermostichus strains that have extra homologs of cpcE, cpcF, and cpcT. In addition, phylogenetic analyses of genes coding for PBPs, linkers, and lyases suggest extensive genetic diversity among these thermophiles, which is further discussed with the domain analyses. Moreover, comparative genomic analysis suggests different genomic distributions of PBS-related genes among the thermophiles, indicating probably various regulations of expression. In summary, the comparative analysis elucidates distinct molecular components and organization of PBS in thermophilic cyanobacteria. These results provide insights into the PBS components of thermophilic cyanobacteria and fundamental knowledge for future research regarding structures, functions, and photosynthetic improvement.

Abstract:
Ten strains of Gram-negative, aerobic, obligately thermophilic bacteria were examined for their response to oxygen toxicity by comparing static with shaken cultures. All of the organisms tested had measurable levels of superoxide dismutase, catalase, and peroxidase. Aeration generally did not result in an increased level of superoxide dismutase in any of the thermophiles. Aeration of organisms obligate for n-alkane substrate caused an increase in cellular peroxidase levels and a corresponding decrease in catalase. The thermophiles that grew on either n-alkanes or complex media did not grow on the hydrocarbon in aerated culture but on a complex medium, aeration effected an increased level of catalase. With the exception of a pink-pigmented thermophile which, when aerated, did not have an increased level of the three oxygen defense enzymes, most of the thermophiles surveyed had an increased level of catalase or peroxidase when exposed to increased oxygen tension. The activity of the enzymes was determined at temperatures from 25 to 65 °C and the former temperature was satisfactory for these experiments.

Abstract:
Marine hydrothermal polymetallic sulfide ores contain high amounts of valuable metals such as Cu, Pb, Zn, Au, Ag, as well as In, Ge, Bi, and Se. Samples from a site in the Indian Ocean were taken during a BGR ship cruise, crushed and sieved for bioleaching experiments to reveal the extraction of the various metals. Chalcopyrite was the main mineral, the total copper content was 38.5 %wt. Comparative bioleaching with mesophilic, moderate thermophilic and thermophilic acidophilic iron- and sulfur-oxidizing bacteria and archaea was investigated. Batch culture experiments were conducted at 2% (w/v) pulp density in shake flasks in the presence of Acidithiobacillus ferrooxidans, Acidiphilium sp. and Acidithiobacillus thiooxidans as mesophiles (30°C), a mixed culture of moderate thermopilic iron- and sulfur oxidizing bacteria (50°C) and the thermophile Acidianus brierleyi (70°C). The results after four weeks showed most effective dissolution of copper in the presence of A. brierleyi (up to 4.3 g/l), compared with moderate thermophiles and mesophiles (3.3 g/l and 2.5 g/l, respectively). Furthermore, the bioleaching performance was approved with dissolved iron concentrations. Conclusively, an increase in temperature from 30 °C to 70 °C had a major impact on bioleaching efficiency. Copper and iron extraction efficiency occurred in the order thermophiles, moderate thermophiles, mesophiles.

Abstract:
Molecular systematic methods were applied in a series of studies designed to resolve the taxonomic relationships of thermophilic actinomycetes known to be difficult to classify using standard taxonomic procedures. The test strains included representatives of clusters defined in an extensiven umerical phenetic survey of thermophilic streptomycetesa nd twelve marker strains. The resultant genotypic data together with the results of corresponding phenotypic studies were used to highlight novel taxa and to improve the circumscription of validly described species. The most comprehensive study was undertaken to clarify relationships within and between representative alkalitolerant, thermophilic and neutrophilic, thermophilic streptomycetes isolated from soil and appropriate marker strains. The resultant data, notably those from DNA: DNA relatedness studies, supported the taxonomic integrity of the validly described species Streptomyces thermodiastaticus, Streptomyces thermoviolaceus and Streptomyces thermovulgaris. However, the genotypic and phenotypic data clearly show that Streptomyces thermonitrificans Desai and Dhala 1967 and Streptomyces thermovulgaris (Henssen 1957) Goodfellow et al. 1987 represent a single species. On the basis of the priority, Streptomyces thermonitrificans is a later subjective synonym of Streptomyces thermovulgaris. Similarly, eight out of eleven representative alkalitolerant, thermophilic isolates and three out of sixteen representative neutrophilic, thermophilic isolates had a combination of properties consistent with their classification as Streptomyces thermovulgaris. One of the remaining alkalitolerant, thermophilic isolate, Streptomyces strain TA56, merited species status. The name Streptomyces thermoalcalitolerans sp. nov. is proposed for this strain. A neutrophilic, thermophilic isolate, Streptomyces strain NAR85, was identified as Streptomyces thermodiastaticus. Four other neutrophilic thermophilic isolates assigned to a numerical phenetic cluster and a thermophilic isolates from poultry faeces were also considered to warrant species status; the names Streptomyces eurythermophilus sp. nov. and Streptomyces thermocoprophilus sp. nov. are proposed to accommodate these strains. It was also concluded that additional comparative taxonomic studies are required to clarify the relationships between additional thermophilic streptomycete strains included in the present investigation. A corresponding polyphasic approach was used to clarify the taxonomy of six thermophilic isolates provisionally assigned to either the genera Amycolatopsis or Excellospora. Two of the isolates, strain NT202 and NT303, had properties consistent with their classification in the genus Amycolatopsis. However, the genotypic and phenotypic data also showed that these strains formed a new centre of taxonomic variation for which the name Amycolatopsis eurythermus sp. nov. is proposed. Similarly, the four remaining strains formed two new centre of taxonomic variation within the genus Excellospora. It is proposed that isolates TA113 and TA114 be designated Excellospora alcalithermophilus sp. nov. Similarly, the name Excellospora thermoalcalitolerans sp. nov. is proposed for strains TA86 and TA111. An emended description is also given for the genus Excellospora.

Abstract:
La température est un paramètre crucial dans le fonctionnement du monde vivant, notamment de la machinerie moléculaire (les protéines) dont la stabilité et l’activité en dépendent sensiblement. Celles-ci sont souvent considérées comme étant équivalentes : si une protéine fonctionne, c’est qu’elle est stable, et vice-versa. Cependant, les protéines des organismes thermophiles, qui prolifèrent dans de températures élevées, sont stables à température ambiante, mais y présentent une faible activité. Cette dernière est optimale à la température de croissance de l’organisme hôte. Lorsqu’on parle de stabilité et d’activité protéique, la rigidité mécanique est souvent utilisée comme paramètre pertinent, offrant une explication simple et attractive à la fois pour la stabilité thermodynamique à haute température et au manque d’activité à des températures plus modérés. La réalité s’avère souvent plus complexe, et les mécanismes moléculaires reliant rigidité/flexibilité avec la stabilité et l’activité sont encore mal compris. Dans ce travail, nous abordons le problème au travers de trois systèmes. Nous avons examiné l’activation thermique des modes fonctionnels du domaine G de la protéine EF ainsi que les homologues mésophiles et thermophiles de la déshydrogénase Lactate/Malate. Par ailleurs, nous avons mis en évidence l’existence d’un paramètre unique (la moyenne des fluctuations atomiques) permettant d’expliquer la dynamique de la protéine lysozyme près de son point de fusion, et ce quelle que soit la nature de l’environnement autour de la protéine (qui décale le point de fusion). Nos conclusions se basent principalement sur une approche in silico où la dynamique moléculaire et des techniques d’échantillonnage améliorées sont utilisées et sont complémentées par des expériences de diffraction de neutrons
Temperature is one of the major factors governing life as demonstrated by the fine tuning of stability and activity of the molecular machinery, proteins in particular. The structural stability and activity of proteins have been often presented as equivalent. However, the thermophilic proteins are stable at ambient condition, but lack activity, the latter recovered only when the temperature increases to match that of the optimal growth condition for the hosting organism. In discussing the protein stability and activity, mechanical rigidity is often used as a relevant parameter, offering a simple and appealing explanation of both the extreme thermodynamic stability and the lack of activity at low temperature. The reality, however, illustrates the complexity of the rigidity/flexibility trade off in ensuring stability and activity through intricate thermodynamic and molecular mechanisms. Here we investigate the problem by studying three study cases. These are used to relate the thermal effects on mechanical properties and the stability and activity of the proteins. For instance, we have probed the thermal activation of functional modes in EF G-domain and Lactate/Malate dehydrogenase mesophilic and thermophilic homologues and verified a “universal” scaling of atomistic fluctuation of the Lysozyme approaching the melting in different environmental conditions. Our conclusions largely rest on an in silico approach, where molecular dynamics and enhanced sampling techniques are utilized, and are often complemented with neutron scattering experiments

Abstract:
La fermentation sombre et les piles à combustible microbiennes (MFC) sont deux technologies émergentes respectivement pour la conversion biologique de l'énergie chimique des composés organiques en hydrogène (H2) et en électricité. En raison des avantages cinétiques et thermodynamiques, la température élevée peut être la clé pour augmenter à la fois la production d'H2 de fermentation sombre et la production d'électricité dans les MFC. Par conséquent, cette thèse se concentre sur la manière dont la température influence la production biologique de H2 et d'électricité à partir d'eaux usées contenant du carbone organique. Deux inocula traités thermiquement (à boues activées fraîches et digérées) ont été comparés pour la production de H2 à partir de xylose à 37, 55 et 70 °C. A la fois à 37 et 55 °C, on obtient un meilleur rendement en H2 par les boues activées fraîches comparé aux boues digérées tandis qu'un très faible rendement en H2 est obtenu par les deux inocula à 70 °C. Ensuite, quatre prétraitements d'inoculum différents (chocs acides, alcalins, thermiques et de congélation) ont été évalués pour créer une efficace communauté productrice de H2 mésophile (37 °C) ou thermophile (55 °C). Les chocs acides et alcalins ont sélectionné des micro-organismes producteurs de H2, appartenant aux Clostridiaceae, au détriment des bactéries produisant du lactate, ce qui a donné respectivement le rendement en H2 le plus élevé à 37 et 55 °C. Bien que le choc thermique ait abouti à un faible rendement en H2 dans un seul lot, il a été montré que la production de H2 par les boues activées fraîches traitées thermiquement augmentait dans l'expérience avec quatre cycles consécutifs. Des boues activées fraîches et traitées thermiquement ont été sélectionnées comme inoculum pour la production continue de H2 à partir d'une eau usée synthétique contenant du xylose dans un réacteur à lit fluidisé (FBR) mésophile (37 °C) et thermophile (55-70 °C, augmenté par étapes). Un rendement en H2 plus élevé a été obtenu dans le FBR thermophile que dans le FBR mésophile. En outre, la production de H2 à 70 °C, qui a échoué dans l'étude précédente, a été couronnée de succès dans le FBR, avec un rendement stable de 1.2 mol H2 mol-1 xylose. La température de fonctionnement de 70 °C s'est également révélée optimale pour la production de H2 à partir d'eaux usées thermomécaniques (TMP) dans un incubateur à gradient de température, car la culture en batch à 70 ° C. Une approche de l'ARN a été utilisée pour étudier la structure et le rôle des communautés microbiennes attachées à l'anode, attachées à la membrane et planctoniques dans un MFC mésophile (37 °C) et thermophile (55 °C) alimenté au xylose. Une communauté anodine dominée par Geobacteraceae a soutenu la production d'électricité à 37 °C, alors que l'établissement de micro-organismes méthanogènes et H2 oxydants a entraîné une faible production d'électricité à 55 °C. Cependant, le développement d'une communauté exoélectrogène thermophile peut être favorisé en appliquant une stratégie de démarrage qui comprend l'imposition d'un potentiel négatif à l'anode et l'inhibition chimique des méthanogènes. Une communauté exoélectrogénique mésophile a également été montré pour produire de l'électricité à partir d'eaux usées de TMP dans un MFC à flux ascendant exploité à 37 °C. En conclusion, une production de H2 plus élevé et plus stable peut être obtenu dans une fermentation sombre thermophile plutôt que mésophile. La fermentation sombre à 70 °C est particulièrement appropriée pour le traitement des eaux usées de TMP car elle est libérée à haute température (50-80 °C) et pourrait être traitée sur site. Les eaux usées de TMP peuvent également être utilisées comme substrat pour la production d'électricité dans les MFC mésophiles. La production d'électricité dans les MFC thermophiles est faisable, mais l'enrichissement des micro-organismes exoélectrogènes thermophiles peut nécessiter une longue période de démarrage
Dark fermentation and microbial fuel cells (MFCs) are two emerging technologies for biological conversion of the chemical energy of organic compounds into hydrogen (H2) and electricity, respectively. Due to kinetic and thermodynamic advantages, high temperature can be the key for increasing both dark fermentative H2 production and electricity production in MFCs. Therefore, this thesis focuses on delineating how temperature influences biological production of H2 and electricity from organic carbon-containing wastewaters. Two heat-treated inocula (fresh and digested activated sludge) were compared, for H2 production from xylose at 37, 55 and 70 °C. At both 37 and 55 °C, a higher H2 yield was achieved by the fresh than digested activated sludge, whereas a very low H2 yield was obtained by both inocula at 70 °C. Then, four different inoculum pretreatments (acidic, alkaline, heat and freezing shocks) were evaluated for creating an efficient mesophilic (37 °C) or thermophilic (55 °C) H2 producing community. Acidic and alkaline shocks selected known H2 producing microorganisms belonging to Clostridiaceae at the expenses of lactate producing bacteria, resulting in the highest H2 yield at 37 and 55 °C, respectively. Although a heat shock resulted in a low H2 yield in a single batch, H2 production by the heat-treated fresh activated sludge was shown to increase in the experiment with four consecutive batch cycles.Heat-treated fresh activated sludge was selected as inoculum for continuous H2 production from a xylose-containing synthetic wastewater in a mesophilic (37 °C) and a thermophilic (55-70 °C, increased stepwise) fluidized bed reactor (FBR). A higher H2 yield was obtained in the thermophilic than in the mesophilic FBR. Furthermore, H2 production at 70 °C, which failed in the earlier batch study, was successful in the FBR, with a stable yield of 1.2 mol H2 mol-1 xyloseadded. Operation temperature of 70 °C was also found optimal for H2 production from thermomechanical pulping (TMP) wastewater in a temperature gradient incubator assay.A RNA approach was used to study the structure and role of the anode-attached, membrane-attached and planktonic microbial communities in a mesophilic (37 °C) and a thermophilic (55 °C) two-chamber, xylose-fed MFC. An anode attached community dominated by Geobacteraceae sustained electricity production at 37 °C, whereas the establishment of methanogenic and H2 oxidizing microorganisms resulted in a low electricity production at 55 °C. However, the development of a thermophilic exoelectrogenic community can be promoted by applying a start-up strategy which includes imposing a negative potential to the anode and chemical inhibition of methanogens. A mesophilic exoelectrogenic community was also shown to produce electricity from TMP wastewater in an upflow MFC operated at 37 °C. In conclusion, a higher and more stable H2 yield can be achieved in thermophilic rather than mesophilic dark fermentation. Dark fermentation at 70 °C is particularly suitable for treatment of TMP wastewater as it is released at high temperature (50-80 °C) and could be treated on site. TMP wastewater can be also used as substrate for electricity production in mesophilic MFCs. Electricity production in thermophilic MFCs is feasible, but enrichment of thermophilic exoelectrogenic microorganisms may require a long start-up period

Abstract:
A reverse transcription reaction allows the production of complementary DNA (cDNA) using an RNA template and relies on polymerases displaying reverse transcriptase (RT) activity. This process, with major applications in both research and in medical diagnostics, is often limited by the nature of the RTs available. RNA secondary structure can prove problematic where mesophilic retroviral RTs are used while the alternative approach, using thermophilic DNA polymerases with RT activity, often results in error-prone cDNA production.
This project recognised the need to study other possible sources of thermophilic RTs and outlines the study of four previously uncharacterised Group II Intronencoded proteins (IEP), with RT domains, from thermophilic bacteria. While cloning of the IEP genes and their expression on a small scale proved successful, difficulties were encountered when attempting purification. Despite a lack of overall purity, samples containing IEPs from Thermosinus carboxydivorans and Petrotoga mobilis were shown to have RT activity but characterisation of these IEPs was not carried out. However, an IEP from Bacillus caldovelox proved to be an excellent candidate for characterisation as successful purification was achieved. Enzyme engineering was also performed, fusing a Sac7d domain onto the C-terminus of this protein. These enzymes were shown to have optimum RT activity at 54ºC with activity still being displayed at 76ºC. Other studies on these enzymes showed that, unlike the retroviral RTs, the IEPs displayed no DNA-dependent DNA polymerase activity. The Sac7d fusion protein was also studied in terms of possible enhancements to the RT activity of an IEP. However, preliminary studies showed that, although this domain did not prove to be detrimental to the enzyme, it had little effect on improving the processivity of the RTs.
Although this class of RT looks promising in terms of use as an alternative thermophilic RT, the IEPs studied in this report did incur major limitations during cDNA synthesis, which included lower than expected optimum reaction temperatures, very low fidelity and an inability to synthesise cDNA using complex RNA templates.

Abstract:
Poultry waste composting in natural conditions is a rather slow process. Application of biological preparations based on thermo-tolerant and thermophilic microorganisms can intensify the compost maturation. Novel strains of thermophilic microorganisms — organic matter destructors — were isolated in the current work. The isolates were identified as representatives of Bacillus, Aneurinibacillus, Aeribacillus, and Ureibacillus genera. Isolated strains can be recommended for biological preparations to accelerate composting of poultry litter and other livestock farming waste.
