Aerobic anoxygenic phototrophic bacteria.
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...
متن کاملEvaluation of the Role of Aerobic & Anaerobic Bacteria in the Etiology of Pelvic Inflammatory Disease (PID)
SUMMARY During 2 years, 212 patients with PID and 160 women with no sign of PIO (as control group) were selected for the detection of aerobic an<l anaerobic bacteria and possible cause of the disease. Specimens from 58 patients and 60 controls were taken by laparoscopy and laparotomy, 154 patients and 100 controls by swabs from endocervical canal. From laparoscopy and laparotomy group(58) 9 ...
متن کاملAerobic Polychlorinated Biphenyl-Degrading Bacteria
Several bacterial isolates were characterized based on their abilities to degrade specific polychlorinated biphenyls (PCBs) and their 16s rRNA gene sequences. The members of one group of bacteria consisting of Alcaligenes species, including the PCB-degrading bacterium Alcaligenes eutrophus H850, had strong abilities to degrade a broad range of PCBs but not the di-para-chlorine-substituted conge...
متن کاملBiology of moderately halophilic aerobic bacteria.
The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while synthesizing or accumulating organic sol...
متن کاملAerobic methanotrophic bacteria of cold ecosystems.
This review summarizes the recent advances in understanding the ecophysiological role and structure-function features of methanotrophic bacteria living in various cold ecosystems. The occurrence of methanotrophs in a majority of psychrosphere sites was verified by direct measurement of their methane-utilizing activity, by electron microscopy and immunofluorescent observations, and analyses of s...
