The Alpha-Proteobacteria is predominantly responsible for the degradation of organosulfur compounds, including the algal osmolyte dimethylsulfoniopropionate. Silicobacter pomeroyi carries out many organic sulfur transformations that occur in natural bacterial communities in the surface ocean. The bacterium converts dimethylsulfoniopropionate to both dimethylsulfide and methanethiol. Through[..]
Nitrosomonas europaea is a Gram-negative obligate chemolithoautotroph, which derives all its energy and reductant for growth from the aerobic oxidation of ammonia to nitrite. The bacterium participates in the biogeochemical Nitrogen cycle in the process of nitrification (Ref.1). A key step in peptidoglycan layer assembly and deposition in the cell wall of N.europaea is the[..]
Methanotrophs are a unique group of Gram-negative bacteria that grow aerobically on methane and utilize methane as the sole source of carbon and energy. Methanotrophs such as Methylococcus capsulatus(M. capsulatus) are responsible for the oxidation of biologically generated methane, and they are therefore of great environmental importance in reducing the amount of this greenhouse gas[..]
Listeria monocytogenes(L. monocytogenes) is a Gram-positive facultative intracellular bacterial pathogen that elicits a strong cellular immune response following infection and therefore has potential use as a vaccine vector. However, while infections by L. monocytogenes are fairly rare and can readily be controlled by a number of antibiotics, the organism can nevertheless[..]
Lactic acid bacteria are a heterogeneous group of microorganisms that convert carbohydrates into lactic acid. They comprise both pathogens (such as Streptococcus pneumoniae or Streptococcus pyogenes) and useful bacteria (such as Streptococcus thermophilus and Lactococcus lactis (L. lactis), which were used for millennia in milk fermentation). In nature,[..]
Bordetella pertussis, Bordetella parapertussis and Bordetella bronchiseptica are closely related Gram-negative Beta-proteobacteria that colonizes the respiratory tracts of mammals. B. bronchiseptica causes chronic respiratory infections in a wide range of animals. D-Alanine is a necessary precursor in the biosynthesis of cell wall in this bacterium[..]
The genus Bordetella in the family Alcaligenaceae, comprises five species(Bordetella pertussis, Bordetella parapertussis and Bordetella bronchiseptica, Bordetella hinzii and Bordetella avium ), four of which cause infections of the upper respiratory tract in different host organisms. They are closely related Gram-negative Beta-proteobacteria Bordetella pertussis is[..]
Bacillus species and other microbes with pH optima for growth higher than pH 9 are defined as alkaliphiles. A large number of alkaliphilic Bacillus strains producing useful enzymes, have been isolated from various environments. Bacillus halodurans(B. halodurans) is an alkaliphilic Bacillus species that grows optimally above pH 9.5. It is the second Bacillus species whose entire[..]
Bacilli are an extremely diverse group of bacteria that include both the causative agent of anthrax (Bacillus anthracis) as well as several species that synthesize important antibiotics. Bacilli are rod-shaped, Gram-positive, sporulating, aerobes or facultative anaerobes. Bacilli exhibit an array of physiologic abilities that allow them to live in a wide range of habitats, including many[..]
Bacilli are rod-shaped, Gram-positive, sporulating, aerobes or facultative anaerobes. Bacilli exhibit an array of physiologic abilities that allow them to live in a wide range of habitats, including many extreme habitats such as desert sands, hot springs, and Arctic soils. Species in the genus Bacillus can be thermophilic, psychrophilic, acidophilic, alkaliphilic, halotolerant, or halophilic[..]
