Ralstonia solanacearum is a Gram negative β-proteobacteria. It is an aerobic non-spore-forming, Gram-negative, plant pathogen. R. solanacearum is soil-borne and motile with a polar flagellar tuft. It colonises the xylem, causing bacterial wilt in a very wide range of potential host plants (Ref.1). Although R. solanacearum is considered a plant[..]
Rhodopseudomonas palustris is a rod-shaped, Gram-negative purple nonsulfur bacterium. It is an alphaproteobacterium that serves as a model organism for studies of photophosphorylation, regulation of nitrogen fixation, production of hydrogen as a biofuel, and anaerobic degradation of aromatic compounds. This bacterium is able to transition between anaerobic photoautotrophic growth, anaerobic[..]
Pseudomonas syringae is one of the best studied plant pathogen with more than 50 pathovars. Each pathovar is known to infect a characteristic group of host plant species (Ref.1). P. syringae is a Gram-negative bacterium and its different strains are known for their diverse interactions with plants. Among these strains, P. syringae pv. tabaci is a non-host pathogen of[..]
Pseudomonas putida is a Gram-negative, rod-shaped, saprotrophic soil bacterium (Ref.1). It has been reported as opportunistic human pathogens capable of causing nosocomial infections. P. putida exhibits an amazing ability to metabolize a wide range of biogenic and xenobiotic compounds (Ref.2). As a frequent inhabitant of sites polluted with toxic chemicals,[..]
Glutathione is a sulfhydryl (-SH) antioxidant, antitoxin, and enzyme cofactor. It is ubiquitous in animals, plants, and microorganisms, and being water soluble is found mainly in the cell cytosol and other aqueous phases of the living system. Glutathione is a tripeptide composed of Glutamate, Cysteine and Glycine that has numerous important functions within cells. Glutathione is[..]
Shewanella oneidensis is a facultative aerobic Gram-negative bacterium. It uses oxygen as the terminal electron acceptor during aerobic respiration, but during anaerobic conditions, S. oneidensis undertakes respiration by reducing alternative terminal electron acceptors such as oxidized metals, fumarate, nitrate etc. The microbe can directly reduce both uranium and chromium[..]
Xylella fastidiosa is a Gram-negative, fastidious, xylem-limited bacterium that causes a range of economically important plant diseases. It causes citrus variegated chlorosis-a serious disease of orange trees. It is responsible for pathogenicity and virulence involving toxins, antibiotics and ion sequestration systems. Glutathione is a tripeptide present in Xylella sp., which[..]
Vibrio vulnificus is an etiologic agent for severe human infection acquired through wounds or contaminated seafood. This is a lactose-fermenting, halophilic, Gram-negative, opportunistic pathogen, is found in estuarine environments and is associated with various marine species such as plankton, shellfish (Oysters, Clams, and Crabs), and finfish (Ref.1). V. vulnificus belong[..]
Vibrio parahaemolyticus, a Gram-negative marine bacterium, is a worldwide cause of food-borne gastroenteritis. The organism is phylogenetically close to V. cholerae, the causative agent of cholera. This universal marine pathogen is used as a bacterial model to clarify the various physiological phenomena of its native and host environments (Ref.1 & 2).
Glutathione in[..]
Vibrio fischeri is a Gram-negative heterotrophic bacterium, belonging to the Vibrionaceae, a large family within the Gamma-proteobacteria, consisting of many species that are characterized by both cooperative and pathogenic interactions with animal tissue. V. fischeri has a worldwide distribution, principally in temperate and subtropical waters, where it occupies a variety of niches. In[..]
Vibrio cholerae is a facultative anaerobic, Gram-negative, crescent-shaped, motile rod like bacterium, and the causative infectious agent of the diarrheal disease, Cholera. It colonizes the mucosal surface of the human small intestine and secretes cholera toxin. The toxin stimulates secretion of water and electrolytes by the cells of the small intestine, leading to the severe watery diarrhoea[..]
Synechocystiae are unicellular, photoautotrophic, facultative glucose-heterotrophic bacteria. They are oxygenic photosynthetic with two photosystems at their disposal, similar to those in algae and plants, and they can fix nitrogen. Synechocystis sp. PCC6803 can grow in the absence of photosynthesis if a suitable fixed-carbon source such as glucose is provided. The total length of[..]
