One hundred and fifty-eight anaerobic organisms from 147 patients were isolated from 15,250 consecutive clean mid-stream or catheter urine specimens. The pathogenicity of the anaerobic genera commonly isolated from urine is reviewed and discussed. Failure to establish anaerobic isolates as pathogens and a paucity of reported cases proving anaerobic bacteria as significant causes of urinary trac...

To our knowledge, the effects of the use of improved anaerobic techniques have not been documented. We compared data on patients during 2 different time periods-the first when anaerobic cultures were done by standard techniques (the control or "before" group) and the second when anaerobic cultures were done after an intensive program to improve anaerobic techniques (IAT). The program consisted ...

BACKGROUND Children's physical activity patterns are characterized by short-term anaerobic activities. Anaerobic exercise performance in children with cystic fibrosis (CF) has received little attention compared to aerobic performance. This study investigated the effects of anaerobic training in children with CF. DESIGN AND METHODS Twenty patients were randomly assigned to the training group (...

Bacillus subtilis grows in the absence of oxygen using nitrate ammonification and various fermentation processes. Lactate, acetate, and 2,3-butanediol were identified in the growth medium as the major anaerobic fermentation products by using high-performance liquid chromatography. Lactate formation was found to be dependent on the lctEP locus, encoding lactate dehydrogenase and a putative lacta...

Since the earlier anaerobic treatment systems, the design concepts were improved from classic reactors like septic tanks and anaerobic ponds, to modern high rate reactor configurations like anaerobic filters, UASB, EGSB, fixed film fluidized bed and expanded bed reactors, and others. In this paper, anaerobic reactors are evaluated considering the historical evolution and types of wastewaters. T...

As a result of the ambiguity and complexity surrounding anaerobic digester foaming, efforts have been made by various researchers to understand the process of anaerobic digester foaming so as to proffer a solution that can be universally applied rather than site specific. All attempts ranging from experimental analysis to comparative review of other process has not fully explained the condition...

The isolation of anaerobic bacteria from routine wound swabs by three procedures was evaluated. Recovery of anaerobic organisms was doubled by immediate incubation of seeded plates, and the recovery could be further dramatically improved by the use of prereduced media, in conjunction with an anaerobic chamber. Recommendations for the treatment of swabs and cultures for anaerobic investigation a...

Clinical trials were carried out in order to determine the value of metronidazole in preventing the development of anaerobic infections after surgery. Following a successful controlled trial of hysterectomy patients, among whom the prophylactic use of oral metronidazole resulted in a reduction of the anaerobic sepsis rate from 25% to nil, further trials were carried out with patients having urg...

The objective of this paper is simultaneous of aerobic and anaerobic process for phosphorus removal from a dairy wastewater. The system consists of a granular sequencing batch reactor (SBR) working under alternating aerobic/anaerobic conditions. In order to analyze the process, four significant variables viz. MLSS, COD/N ratio, aeration time and cycling time and four dependent parameters as the...

The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lago...
