An optical microbial biosensor was described for the detection of methyl parathion pesticide. Whole cells of Flavobacterium sp. were immobilized by trapping in glass fiber filter and were used as biocomponent along with optic fiber system. Flavobacterium sp. has the organophosphorus hydrolase enzyme, which hydrolyzes the methyl parathion into detectable product p-nitrophenol. The immobilized mi...

A commercial bullfrog (Rana castesbeiana) operation in south Georgia had multiple epizootics of systemic bacterial infections over a 3-year period, 1998-2000. A number of potential pathogens (Aeromonas hydrophila, Chryseobacterium (Flavobacterium) meningosepticum, Chryseobacterium (Flavobacterium) indolgenes, Edwardsiella tarda, Citrobacterfreundii, Pseudomonas spp., and (Streptococcus iniae) w...

Macrae, I. C. (Cornell University, Ithaca, N.Y.), and M. Alexander. Metabolism of phenoxyalkyl carboxylic acids by a Flavobacterium species. J. Bacteriol. 86:1231-1235. 1963.-A Flavobacterium sp. isolated from soil and grown in media containing 4-(2,4-dichlorophenoxy) butyric acid metabolized omega-linked 2,4-dichlorophenoxyalkyl carboxylic acids in the series from 3-(2,4-dichlorophenoxy)propio...

Airborne microorganisms have been studied for centuries, but the majority of this research has relied on cultivation-dependent surveys that may not capture all of the microbial diversity in the atmosphere. As a result, our understanding of airborne microbial ecology is limited despite the relevance of airborne microbes to human health, various ecosystem functions, and environmental quality. Cul...

Draft genome sequences of Elizabethkingia meningoseptica and representatives of each of its four historically described genomospecies were sequenced here. Preliminary analysis suggests that Elizabethkingia miricola belongs to genomospecies 2, and both Elizabethkingia anophelis and Elizabethkingia endophytica are most similar to genomospecies 1.

We announce here the draft genome assembly of Flavobacterium columnare CSF-298-10, a strain isolated from an outbreak of columnaris disease at a commercial trout farm in Hagerman Valley, Idaho, USA. The complete genome consists of 13 contigs totaling 3,284,579 bp, with an average G+C content of 31.5% and 2,933 predicted coding genes.

Several microorganisms were isolated from soil/sediment samples of Antarctic Peninsula. The enrichment technique using (RS)-1-(phenyl)ethanol as a carbon source allowed us to isolate 232 psychrophile/psychrotroph microorganisms. We also evaluated the enzyme activity (oxidoreductases) for enantioselective oxidation reactions, by using derivatives of (RS)-1-(phenyl)ethanol as substrates. Among th...

A soil organism of the genus Flavobacterium was isolated from a medium containing folic acid as the sole source of carbon and nitrogen (ATCC 25012). This organism resembles but is not identical with a previously described strain, Flavobacterium polyglutamicum. It utilizes the glutamate released from pteroylmonoglutamate by the action of an intracellular enzyme, folate amidase. The relative rate...
