The field of photobiology is concerned with the interactions between light and living matter. For Bacteria this interaction serves three recognisable physiological functions: provision of energy, protection against excess radiation and signalling (for motility and gene expression). The chemical structure of the primary light-absorbing components in biology (the chromophores of photoactive proteins) is surprisingly simple: tetrapyrroles, polyenes and derivatised aromats are the most abundant… Expand
Engineering retinal-based phototrophy via a complementary photosystem in Synechocystis sp. PCC6803
TLDR
This thesis focuses on expressing two retinal-based pumps, proteorhodopsin (PR) and Gloeobacter rhodopin (GR), into Synechocystis sp. Expand
H2 production in Rhodopseudomonas palustris as a way to cope with high light intensities.
TLDR
Investigating whether H2 photo-evolution could represent, for Rhodopseudomonas palustris 42OL, a safety valve to dissipate an excess of reducing power generated under high light intensities showed a positive correlation with the maximum electron transfer rate (rETRmax). Expand
Combining retinal-based and chlorophyll-based (oxygenic) photosynthesis: Proteorhodopsin expression increases growth rate and fitness of a ∆PSI strain of Synechocystis sp. PCC6803.
TLDR
Growth-rate measurements, competition experiments and physiological characterization of the proteorhodopsin-expressing strains, relative to the ΔPSI control strain, allow us to conclude that proteor Hodopsin can enhance the rate of photoheterotrophic growth of Δ PSI Synechocystis strain. Expand
retinal-based phototrophy via a complementary photosystem in Synechocystis sp . PCC 6803
Cyanobacteria, the only bacteria that can carry out oxygenic, i.e. plant-type, photosynthesis, can be engineered with the methods of synthetic biology so that they acquire the ability to convert CO2Expand
Microarray analysis of high light intensity stress on hydrogen production metabolism of Rhodobacter capsulatus
Abstract Biohydrogen obtained from purple non sulfur bacteria (PNSB) is an environmentally friendly alternative for hydrogen production. PNSB can be employed in large scale outdoor photobioreactorsExpand
A high resolution microscopy study of biological components for the incorporation in opto-electronic hybrid devices
Optical microscopy and scanning probe microscopy techniques have been utilised to acquire high resolution topography and fluorescence images of several biological samples. Applying these techniquesExpand
Biological HRPs in wastewater
Abstract Biological high-risk pollutants (HRPs) have become a serious threat to human health worldwide, and wastewater is one of the major sources of them in a natural environment. Despite theExpand
Synechocystis: Not Just a Plug-Bug for CO2, but a Green E. coli
TLDR
It is argued that this approach will be more likely to be successful if organisms such as Synechocystis are not perceived as mere chassis for CO2 fixation, but rather considered as the “green” E. coli. Expand

The phycobilisome, a light-harvesting complex responsive to environmental conditions.
TLDR
The phycobilisome, the light-harvesting apparatus of cyanobacteria and red algae, is discussed, which allows these organisms to efficiently utilize available light energy to drive photosynthetic electron transport and CO2 fixation. Expand
Taxonomy, Phylogeny, and General Ecology of Anoxygenic Phototrophic Bacteria
TLDR
The ecological niches of anoxygenic phototrophic bacteria are anoxic parts of waters and sediments, which receive light of sufficient quantity and quality to allowPhototrophic development. Expand
Photoactive yellow protein from the purple phototrophic bacterium, Ectothiorhodospira halophila. Quantum yield of photobleaching and effects of temperature, alcohols, glycerol, and sucrose on kinetics of photobleaching and recovery.
TLDR
The present experiments demonstrate that temperature, glycerol, sucrose, and various alcohol-water mixtures strongly influence the kinetics of photobleaching and recovery, and conclude that the change in conformation of the protein induced by light exposes a hydrophobic site to the solvent. Expand
Properties of a water-soluble, yellow protein isolated from a halophilic phototrophic bacterium that has photochemical activity analogous to sensory rhodopsin.
TLDR
The absorption at 446 nm in the native protein appears to result from a 106-nm red shift of the chromophore induced by the protein, which is remarkably similar to those of sensory rhodopsin from Halobacterium. Expand
A functional model for the role of cytochrome b559 in the protection against donor and acceptor side photoinhibition.

  • Proceedings of the National Academy of Sciences of the United States of America
  • 1993
TLDR
This conclusion has been incorporated into a model that further suggests that in its high potential form the cytochrome primarily acts to protect against donor side photoinhibition due to increased lifetime of highly oxidized species as previously proposed by Thompson and Brudvig. Expand
Energy metabolism in the cyanobacterium Plectonema boryanum: participation of the thylakoid photosynthetic electron transfer chain in the dark respiration of NADPH and NADH
The oxidation of NADPH and NADH was studied in the light and in the dark using sonically derived membrane vesicles and osmotically shocked spheroplasts. These two types of cell-free membraneExpand
Characterization of the light-regulated operon encoding the phycoerythrin-associated linker proteins from the cyanobacterium Fremyella diplosiphon
TLDR
The complete nucleotide sequence of another operon, cpeCD, that encodes the linker proteins associated with phycoerythrin hexamers in the phycobilisome is isolated and determined. Expand
Characteristics of cyclic electron transport in the cyanobacterium Phormidium laminosum
TLDR
The data presented indicate that the cyanobacterial and higher-plant cyclic electron transfer processes are similar in over all mechanism but differ in detail, both at the level of FQR activity and the cytochrome bf complex. Expand
Photoinduced degradation of the D1 polypeptide in isolated reaction centers of photosystem II: evidence for an autoproteolytic process triggered by the oxidizing side of the photosystem.
  • C. Shipton, J. Barber
  • Chemistry, Medicine
  • Proceedings of the National Academy of Sciences of the United States of America
  • 1991
TLDR
The results indicate that the photoinduced degradation of D1 (and D2) does not involve exogenous proteases but is most likely an autoproteolytic process and the photochemical damage giving rise to D1 and D2 degradation occurs on the oxidizing rather than the reducing side of photosystem II and involves photooxidation of the accessory pigments.

TLDR
The behavior of carotenoids in photosynthetic bacterial reaction centers and light-harvesting complexes is correlated with data from experiments carried out on carOTenoids and model systems in vitro. Expand
