References 55Life as we know it today exists largely because of photosynthesis, the process through which light energy is converted into chemical energy by plants, algae, and photosynthetic bacteria (Priestley, 1772; Barnes, 1893; Wurmser, 1925; Van Niel, 1941; Clayton & Sistrom, 1978; Blankenship et al. 1995; Ort & Yocum, 1996). Historically, photosynthetic organisms are grouped into two classes. When photosynthesis is carried out in the presence of air it is called oxygenic photosynthesis (Ort & Yocum, 1996). Otherwise, it is anoxygenic (Blankenship et al. 1995). Higher plants, algae and cyanobacteria perform oxygenic photosynthesis, which involves reduction of carbon dioxide to carbohydrate and oxidation of water to produce molecular oxygen. Some photosynthetic bacteria, such as purple bacteria, carry out anoxygenic photosynthesis that involves oxidation of molecules other than water. In spite of these differences, the general principles of energy transduction are the same in anoxygenic and oxygenic photosynthesis (Van Niel, 1931, 1941; Stanier, 1961; Wraight, 1982; Gest, 1993). The primary processes of photosynthesis involve absorption of photons by light-harvesting complexes (LHs), transfer of excitation energy from LHs to the photosynthetic reaction centers (RCs), and the primary charge separation across the photosynthetic membrane (Sauer, 1975; Knox, 1977; Fleming & van Grondelle, 1994; van Grondelle et al. 1994). In this article, we will focus on the anoxygenic photosynthetic process in purple bacteria, since its photosynthetic system is the most studied and best characterized during the past 50 years.

Abstract:
There are two main types of bacterial photosynthesis: oxygenic (cyanobacteria) and anoxygenic (sulfur and non-sulfur phototrophs). Molecular mechanisms of photosynthesis in the phototrophic microorganisms can differ and depend on their location and pigments in the cells. This paper describes bacteria capable of molecular oxidizing hydrogen sulfide, specifically the families Chromatiaceae and Chlorobiaceae, also known as purple and green sulfur bacteria in the process of anoxygenic photosynthesis. Further, it analyzes certain important physiological processes, especially those which are characteristic for these bacterial families. Primarily, the molecular metabolism of sulfur, which oxidizes hydrogen sulfide to elementary molecular sulfur, as well as photosynthetic processes taking place inside of cells are presented. Particular attention is paid to the description of the molecular structure of the photosynthetic apparatus in these two families of phototrophs. Moreover, some of their molecular biotechnological perspectives are discussed.

Abstract:
The use of anorganic fertilizers is most popular among farmers, the lack of subsidies from the government for anorganic fertilizers so that the scarcity of fertilizers becomes important problem for farmers. The purpose of this activity is to assist farmers in the use of photosynthetic bacteria as fertilizers for plants. The method used is in the form of counseling, and mentoring in the practice of cultivated bacterial photosynthesis for application in fields. The results of the activities showed that before the training the majority of trainees (82.5%) did not know and understand photosynthetic bacterial fertilizers, after training the majority of trainees (80.4%) knew and understood, and were skilled in making and using photosynthetic bacteria. Participation and enthusiasm were shown by the participants during the activity.

Abstract:
Photosynthesis is a key process for the establishment and maintenance of life on earth, and it is manifested in several major lineages of the prokaryote tree of life. The evolution of photosynthesis in anoxygenic photosynthetic bacteria is of major interest as these have the most ancient roots of photosynthetic systems. The phylogenetic relations between anoxygenic phototrophic bacteria were compared on the basis of sequences of key proteins of the type-II photosynthetic reaction center, including PufLM and PufH (PuhA), and a key enzyme of bacteriochlorophyll biosynthesis, the light-independent chlorophyllide reductase BchXYZ. The latter was common to all anoxygenic phototrophic bacteria, including those with a type-I and those with a type-II photosynthetic reaction center. The phylogenetic considerations included cultured phototrophic bacteria from several phyla, including Proteobacteria (138 species), Chloroflexi (five species), Chlorobi (six species), as well as Heliobacterium modesticaldum (Firmicutes), Chloracidobacterium acidophilum (Acidobacteria), and Gemmatimonas phototrophica (Gemmatimonadetes). Whenever available, type strains were studied. Phylogenetic relationships based on a photosynthesis tree (PS tree, including sequences of PufHLM-BchXYZ) were compared with those of 16S rRNA gene sequences (RNS tree). Despite some significant differences, large parts were congruent between the 16S rRNA phylogeny and photosynthesis proteins. The phylogenetic relations demonstrated that bacteriochlorophyll biosynthesis had evolved in ancestors of phototrophic green bacteria much earlier as compared to phototrophic purple bacteria and that multiple events independently formed different lineages of aerobic phototrophic purple bacteria, many of which have very ancient roots. The Rhodobacterales clearly represented the youngest group, which was separated from other Proteobacteria by a large evolutionary gap.

Abstract:
ABSTRACT Primer sets were designed to target specific 16S ribosomal DNA (rDNA) sequences of photosynthetic bacteria, including the green sulfur bacteria, the green nonsulfur bacteria, and the members of theHeliobacteriaceae (a gram-positive phylum). Due to the phylogenetic diversity of purple sulfur and purple nonsulfur phototrophs, the 16S rDNA gene was not an appropriate target for phylogenetic rDNA primers. Thus, a primer set was designed that targets the pufM gene, encoding the M subunit of the photosynthetic reaction center, which is universally distributed among purple phototrophic bacteria. The pufM primer set amplified DNAs not only from purple sulfur and purple nonsulfur phototrophs but also from Chloroflexus species, which also produce a reaction center like that of the purple bacteria. Although the purple bacterial reaction center structurally resembles green plant photosystem II, the pufM primers did not amplify cyanobacterial DNA, further indicating their specificity for purple anoxyphototrophs. This combination of phylogenetic- and photosynthesis-specific primers covers all groups of known anoxygenic phototrophs and as such shows promise as a molecular tool for the rapid assessment of natural samples in ecological studies of these organisms.

Abstract:
SUMMARY The aerobic anoxygenic phototrophic bacteria are a relatively recently discovered bacterial group. Although taxonomically and phylogenetically heterogeneous, these bacteria share the following distinguishing features: the presence of bacteriochlorophyll a incorporated into reaction center and light-harvesting complexes, low levels of the photosynthetic unit in cells, an abundance of carotenoids, a strong inhibition by light of bacteriochlorophyll synthesis, and the inability to grow photosynthetically under anaerobic conditions. Aerobic anoxygenic phototrophic bacteria are classified in two marine (Erythrobacter and Roseobacter) and six freshwater (Acidiphilium, Erythromicrobium, Erythromonas, Porphyrobacter, Roseococcus, and Sandaracinobacter) genera, which phylogenetically belong to the α-1, α-3, and α-4 subclasses of the class Proteobacteria. Despite this phylogenetic information, the evolution and ancestry of their photosynthetic properties are unclear. We discuss several current proposals for the evolutionary origin of aerobic phototrophic bacteria. The closest phylogenetic relatives of aerobic phototrophic bacteria include facultatively anaerobic purple nonsulfur phototrophic bacteria. Since these two bacterial groups share many properties, yet have significant differences, we compare and contrast their physiology, with an emphasis on morphology and photosynthetic and other metabolic processes.

Abstract:
Photosynthesis—both oxygenic and more ancient anoxygenic forms—has fueled the bulk of primary productivity on Earth since it first evolved more than 3.4 billion years ago. However, the early evolutionary history of photosynthesis has been challenging to interpret due to the sparse, scattered distribution of metabolic pathways associated with photosynthesis, long timescales of evolution, and poor sampling of the true environmental diversity of photosynthetic bacteria. Here, we reconsider longstanding hypotheses for the evolutionary history of phototrophy by leveraging recent advances in metagenomic sequencing and phylogenetics to analyze relationships among phototrophic organisms and components of their photosynthesis pathways, including reaction centers and individual proteins and complexes involved in the multi-step synthesis of (bacterio)-chlorophyll pigments. We demonstrate that components of the photosynthetic apparatus have undergone extensive, independent histories of horizontal gene transfer. This suggests an evolutionary mode by which modular components of phototrophy are exchanged between diverse taxa in a piecemeal process that has led to biochemical innovation. We hypothesize that the evolution of extant anoxygenic photosynthetic bacteria has been spurred by ecological competition and restricted niches following the evolution of oxygenic Cyanobacteria and the accumulation of O2 in the atmosphere, leading to the relatively late evolution of bacteriochlorophyll pigments and the radiation of diverse crown group anoxygenic phototrophs. This hypothesis expands on the classic “Granick hypothesis” for the stepwise evolution of biochemical pathways, synthesizing recent expansion in our understanding of the diversity of phototrophic organisms as well as their evolving ecological context through Earth history.

Abstract:
The aims of this project were to investigate a range of limitations affecting the electrical performance of bioelectrochemical systems (BES) and their use as analytical tools. The model cyanobacterium Synechocystis sp. PCC6803 was used to characterize light-driven BESs, or biophotovoltaic (BPV) devices. The phycobilisome (PBS) antenna size was altered to modify light absorption. At low to medium light intensities the optimum PBS antenna size was found to consist of one phycocyanin (PC) disc. Incorporating pulsed amplitude fluorescence (PAM) measurements into the BPV characterization allowed simultaneous comparison of photosynthetic efficiency to EET in Synechocystis. Non-photochemical quenching (NPQ) was investigated as a limiting factor in biophotovoltaic efficiency and was found to be reduced in the PBS antenna-truncated mutants. Fluorescence and electrochemical data were combined to develop a framework for quantifying the efficiency of light to bioelectricity conversion. This approach is a first step towards a more comprehensive and detailed set of analytical tools to monitor EET in direct relation to the underlying photosynthetic biology. A set of metabolic electron sinks were deleted to remove a selection of pathways that might compete with extracellular electron transfer (EET). The combined deletion of a bi-directional hydrogenase - HoxH, nitric oxide reductase - NorB, cytochrome-c oxidase - COX, bd-quinol oxidase - cyd, and the respiratory terminal oxidase - ARTO, roughly doubled light driven electron flux to EET. Deletion of nitrate reductase - NarB, and nitrite reductase - NirA, increased EET to a similar degree, but combination with the other knockouts compromised cell viability and did not increase output further. In addition to Synechocystis, the purple non-sulphur α-proteobacterium Rhodopseudomonas palustris CGA009 was used to test the effect of storage molecule synthesis knockout in a more industrially relevant organic carbon source driven BES, or microbial fuel cell (MFC). However, the removal of glycogen and poly-ß-hydroxybutyrate (PHB) did not have a significant effect on electrical output. Finally, the importance of electrode material and design for cell to anode connections in an MFC was investigated. EET from R. palustris was greatly enhanced using custom designed graphene and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) aerogels. Pristine graphene is also shown for the first time to be a viable, low cost alternative to platinum as a cathodic catalyst. Together, these results present a holistic view of major limitations on electrical output from BESs that may contribute to enhancing EET for power generation from MFCs in the long term, and optimization of BPV devices as reliable analytical tools in the short term.

Abstract:
In this thesis light harvesting complexes, the LH2 and core complexes, from several different species of purple photosynthetic bacteria have been analysed both functionally and structurally. Purified monomeric core complexes from Rhodopseudomonas (Rps.) palustris have been used to isolate and identify the putative Protein W. This information was then used to create a Protein W deletion mutant. A low-resolution crystal structure of the monomeric core complex from Allochromatium (Alc.) vinosum is presented which suggests that the LH1 complex is a complete ellipse, unlike the core complex from Rps. palustris. It has previously been shown that some species are able to synthesise LH2 complexes that have different NIR absorption spectra. For example, strains 7050 and 7750 of Rps. acidophila can express both the B800-850 and B800-820 LH2 complexes, whilst strain 10050 only expresses the B800-850 LH2 complex despite evidence to suggest that this strain contains multiple LH2 genes (pucBA genes). It is this homogeneity that has made the LH2 complexes from this strain structurally amenable. Here, genomic DNA from Rps. acidophila strain 10050 has been isolated and sequenced using the next generation sequencing (NGS) technique, Illumina sequencing. So far 8 pucBA gene pairs were identified arranged into 2 distinct operons, one containing B800-850 pucBA genes and pucC, the putative Bchl transporter that is essential for efficient LH2 expression. The second operon contains B800-820 pucBA gene pairs only. Analysis of the protein products of the B800-850 type pucBA gene pairs has shown that none of these proteins match the sequence for the LH2 that is expressed by Rps. acidophila strain 10050. The crystal structure of the LH2 complex from the culture of Rps. acidophila used to isolate the genomic DNA was resolved to 2.05 Å from crystals of the LH2 complex. This structure shows that the protein sequence of the LH2 complex has not changed. Hence, not all the pucBA gene pairs have been identified in the genome sequence data. Currently mate-pair sequencing is being completed to fill in the gaps of sequence data and to complete the genome sequence. LH2 complexes contain carotenoid (Car) and Bchl molecules. In this thesis, the energy transfer mechanisms between Car and Bchl molecules have been investigated using 2-dimensional electronic spectroscopy (2DES). This technique splits the emission and excitation events on 2-dimensions, which can make the less populated ‘dark’ states more visible as overlapping peaks can be separated. Car moleucles are not seen as theoretically efficient in photosynthesis. This is due to short life times of the excited state S2. However, the Car used in photosynthesis have conjugated carbon tails with ≥9 π electrons. According to calculations by Tavan and Schulten, these molecules have the propensity to contain additional excited states that lie below the S2 state that can be involved in energy transfer and increase the efficiency of energy transfer between the Car and Bchl molecules. For the first time an intermediate Car electronic state has been directly observed and shown to be involved in energy transfer between the Car and Bchl molecules.

Abstract:
The primary amino acid sequences of the L, M, and H photosynthetic reaction center peptide subunits from a number of purple non-sulfur bacteria, including Rhodopseudomonas viridis, Rhodobacter sphaeroides, and Rhodobacter capsulatus have been previously shown to be highly homologous, and detailed X-ray crystallographic analyses of reaction centers from two species of purple non-sulfur bacteria, Rps. viridis and R. sphaeroides have shown that all recognized structural and functional features are conserved. Experiments were undertaken to determine whether genes encoding reaction center and light harvesting peptide subunits from one species could be functionally expressed in other species. Plasmid-borne copies of R sphaeroides and Rps. viridis pigment binding-peptide genes were independently introduced into a photosynthetically incompetent R. capsulatus mutant host strain, deficient in all known pigment-binding peptide genes. The R. sphaeroides puf operon, which encodes the L and M subunits of the reaction center as well as both peptide subunits of light harvesting complex I, was shown to be capable of complementing the mutant R. capsulatus host. Hybrid reaction centers, comprised of R. sphaeroides-encoded L and M subunits and an R. capsulatus-encoded H subunit, were formed in addition to the R. sphaeroides-encoded LHI complexes. These hybrid cells were capable of photosynthetic growth, but their slower growth rates under low light conditions and their higher fluorescence emission levels relative to cells containing native complexes, indicated an impairment in energy transduction. The Rps. viridis puf operon was found to be incapable of functional expression in the R. capsulatus mutant host. Introduction of a plasmid-borne copy of the Rps. viridis puhA gene, which encodes the H subunit of the reaction center, into host cells already containing the Rps. viridis puf operon, such that all structural peptides of the Rps. viridis reaction center were present, still did not permit stable assembly of Rps. viridis photosynthetic complexes. RNA blot analysis demonstrated that the barrier to functional expression was not at the level of transcription. Differences between Rps. viridis and R. sphaeroides that may account for their differing abilities to complement the R. capsulatus mutant host strain are discussed.

Abstract:
Photosynthetic membranes were prepared from the cyanobacterium Synechococcus PCC 7942 with oxygen evolving specific activity of 250-300 µmoles 02/ mg chl/hr. The membranes retained activity with a half-life of 4-5 days when stored at 0°C, or when quickly frozen in liquid nitrogen, greater than 95% of the activity remained after 2 months. Attempts to purify homogeneous preparations of photosystem II complexes from these membranes by detergent extraction were unsuccessful as indicated by a lack of a significant increase in oxygen evolution specific activity of the detergent extracts. Photosynthetic membrane detergent extracts usually maintained the same oxygen evolution specific activity as the orginal membranes, and a considerable amount of Photosystem I activity (75 µmoles 02 consumed /mg chl/hr in the Mehler reaction) was still present. The donor side of the photosystem II particles in the detergent extract was intact since the artificial electron acceptor, 2,6-dichiorophenolindophenol (DCPIP), was reduced at a rate comparable to the oxygen evolving activity. All oxygen evolving activity of the detergent extracts was lost when ion-exchange chromatography was used to resolve the co-extracted photosystem II and photosystem I complexes.

Abstract:
Spectral hole-burning is powerful tool for the study of fast relaxation processes (e.g. excited energy transfer - EET, electron transport - e.t.) in photosynthetic systems. Fast e.t. was systematically studied by transient hole-burning (THB) in absorption spectra of reaction centra in purple bacteria and green plants [1]. The THB in fluorescence of PSII particles was described in [2]. Persistent spectral hole-burning (PSHB) enabled to determine the hole-burning mechanism, the EET rate constants, electron-phonon coupling and frequency of protein phonons. The PSHB in fluorescence has been measured in antenna complexes: CP43 and CP47 of PSII [3], B800-850 of purple photosynthetic bacteria [4] and in chlorosomes of green sulphur photosynthetic bacteria [5]. Laser induced hole filling in fluorescence spectra of CP43 of PSII was presented recently in [6]. These data were obtained using wild type organisms. Here, we report an investigation of EET by fluorescence PSHB in photosynthetic antenna using H114Q mutation in the CP47 complex of Synechocystis sp. PCC 6803.

Abstract:
In the primary reaction of photosynthesis an electron is transferred through a pigment-protein complex called reaction center (RC). Starting from the primary donor, a dimer of bacteriochlorophyll molecules called special pair P, the electron reaches a quinone (Q) via two intermediate acceptors, a bacteriochlorophyll-monomer (B) and a bacteriopheophytin (H). In a number of publications this electron transfer process was investigated by transient absorption spectroscopy /1/. At least four kinetic constants of 0.9 ps, 3.5 ps, 200 ps and infinity are required to explain the absorption data /2,3/. The interpretation of these measurements is difficult since absorbance changes from different intermediates interfere. At present the most straight-forward interpretation of the data is the stepwise electron transfer model via the radical pair state P+B–: Complementary information from fluorescence up-conversion experiments is given in this contribution. By this way we follow directly the decay of the excited electronic state of the special pair. The experimental system was optimized to high time resolution and high sensitivity at low repetition rates in order to meet the requirements of the biological samples.
