Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...

Bacteriological examination was performed on bile from 23 patients with acute obstructive suppurative cholangitis. Of 23 bile cultures, 15 yielded aerobic and anaerobic bacteria and 8 yielded aerobic bacteria only. No specimen grew anaerobic bacteria only. A total of 20 cultures yielded a polymicrobial flora, and 3 cultures grew one single aerobic bacterium. Escherichia coli, Klebsiella sp., en...

Resident bacteria are incriminated in the pathogenesis of experimental colitis and inflammatory bowel diseases. We investigated the relative roles of various enteric bacteria populations in the induction and perpetuation of experimental colitis. HLA-B27 transgenic rats received antibiotics (ciprofloxacin, metronidazole, or vancomycin-imipenem) in drinking water or water alone in either preventi...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas pr...

A mathematical model for a hybrid anaerobic reactor (HAR), which uses self-immobilized anaerobic bacterial granules under completely fluidized condition, has been developed. Stoichiometry of glucose fermentation into methane has been considered in this model. The model includes: (1) a biofilm model which describes substrate conversion kinetics within a single granule; (2) a bed fluidization mod...

Objective. Periapical periodontitis is an infectious and inflammatory disease of the periapical tissues caused by oral bacteria invading the root canal. In the present study, profiling of the microbiota in infected root canals was performed using anaerobic culture and molecular biological techniques for bacterial identification. Methods. Informed consent was obtained from all subjects (age rang...

Most gut bacteria are obligate anaerobes and are important for human health. However, little mechanistic insight is available on the health benefits of specific anaerobic gut bacteria. A main obstacle in generating such knowledge is the lack of simple and robust coculturing methods for anaerobic bacteria and oxygen-requiring human cells. Here, we describe the development of a coculture system f...

The volatile fatty acid profiles were determined by a simple gas chromatographic method in 375 microbiologically positive and negative blood cultures. Aerobic bacteria yielded profiles with low content of acids, some of which were chromatographically negative. Anaerobic bacteria produced more acids and more distinctive profiles. The method makes it possible to confirm the microbiological findin...
