We tested 388 strains of anaerobes from 17 genera for the production of phenylacetic acid. The compound was found in only two genera (Bacteroides and Clostridium) but not within all the species of these genera.
2,4,6-Trinitrotoluene ((15)N or (13)C labeled) was added to Norfolk Harbor sediments to test whether anaerobic bacteria use TNT for growth. Stable-isotope probing (SIP)-terminal restriction fragment length polymorphism (TRFLP) detected peaks in the [(15)N]TNT cultures (60, 163, and 168 bp). The 60-bp peak was also present in the [(13)C]TNT cultures and was related to Lysobacter taiwanensis.
OBJECTIVES Silver has historically and extensively been used as a broad-spectrum antimicrobial agent. However, the Food and Drug Administration currently does not recognize colloidal silver as a safe and effective antimicrobial agent. The goal of this study was to further evaluate the antimicrobial efficacy of colloidal silver. DESIGN Several strains of bacteria, fungi, and viruses were grown...
An Edwardsiella piscicida-like species is a Gram-negative facultative anaerobe that causes disease in some fish species. In this report, we present the complete and annotated genome of isolate LADL05-105, recovered from cultured tilapia reared in Louisiana, which contains a chromosome of 4,142,037 bp and no plasmids.
Twenty-one patients with serious infections involving anaerobic bacteria were treated with carbenicillin. Multiple anaerobes were involved in 8 cases, and in 10 cases, facultative anaerobes were also isolated. Bacteroides fragilis was isolated in 10 cases. Results were judged excellent in 7 cases, good in 8 cases, and fair in 5 cases. These data suggest that carbenicillin may be an effective an...
Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at concentrations of 10% or less in the headspace. These results help explain how Geobacter species may survive in oxic subsurface environments, being poised to rapidly take advantage of the development of anoxic cond...
OBJECTIVES : To study the microbiology of sinusitis associated with odontogenic origin. METHODS : Aspirates of 20 acutely and 28 chronically infected maxillary sinuses that were associated with odontogenic infection were processed for aerobic and anaerobic bacteria. RESULTS : A total of 66 isolates were recovered from the 20 cases of acute sinusitis (3.3/specimen), 16 aerobic and facultativ...
It is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. Anaerobes must therefore be sought in a wide variety of clinical specimens. In this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess...

This study aims to isolate and characterize efficient biohydrogen generating facultative anaerobic bacteria from various samples, viz., biogas plant (BGP), municipal sewage (MS), dairy industry treatment (DTP). The physicochemical properties of untreated sludge samples reflect the anoxic state appropriateness substrate for separating bacteria. producing bacterial strains were separated methanog...
