phylogenetic position of chitinophaga pinensis in the flexibacter-bacteroides-cytophaga phylum.comparison of the 16s rrna gene sequence determined for chitinophaga pinensis showed that this species is most closely related to flexibacter filiformis in the flexibacter-bacteroides-cytophaga phylum. these two chitinolytic bacteria, which are characterized by transformation into spherical bodies on ageing, belong to a strongly supported lineage that also includes cytophaga arvensicola, flavobacterium ferrugineum and flexibacter sancti. the lineage is distinct from the microcyst-forming species ...199910319467
flavobacterium hibernum sp. nov., a lactose-utilizing bacterium from a freshwater antarctic lake.four freshwater antarctic lakes were examined for the presence of beta-galactosidase-producing bacteria using mineral medium enrichments and lactose. enrichments from only one of the lakes produced growth and two strains were isolated that were very similar in phenotype and fatty acid profile, and shared considerable homology in their dna (dna-dna hybridization = 93 +/- 7%). the strains were psychrotrophic with theoretical tmax, tmin and topt of 30-31, -7 degrees and 26 degrees c, respectively. ...19989828443
development of techniques to genetically manipulate members of the genera cytophaga, flavobacterium, flexibacter, and sporocytophaga.the bacteroides-cytophaga-flavobacterium branch of the eubacterial phylogenetic tree contains a diverse group of bacterial species. techniques for the genetic manipulation of bacteroides spp. are well developed (a. a. salyers, n. b. shoemaker, and e. p. guthrie, crit. rev. microbiol. 14:49-71, 1987). recently we developed techniques to genetically manipulate the gliding bacterium cytophaga johnsonae (m. j. mcbride and m. j. kempf, j. bacteriol. 178:583-590, 1996). we now demonstrate that some of ...19968702294
identification and evolution of the cellulolytic microflora present during composting of cattle manure: on the role of actinomycetes sp.population changes in cellulolytic microflora were studied during composting of cattle manure. six bacterial and nine actinomycetes species were isolated. among the isolates, two actinomycetes, micromonospora chalcae and pseudonocardia thermophila, were cellulolytic strains which were numerically dominant and might therefore play a notable role in the degradation of cellulose in cattle manure. fungi were practically absent during the process, but two cellulose-degrading bacterial species, sporoc ...19846508072
unusual sulfonolipids are characteristic of the cytophaga-flexibacter group.capnocytophaga spp. contain a group of unusual sulfonolipids, called capnoids (w. godchaux iii and e. r. leadbetter, j. bacteriol. 144:592-602, 1980). one of these lipids, capnine, is 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid; the others are, apparently, n-acylated versions of capnine. the lipids were found, in amounts ranging from 2.5 to 16 mumol of capnoid sulfur per g of cells (wet weight), in two cytophaga spp. and also in several closely related organisms: several capnocytophaga ...19836298180

[bacteria of the flexibacter/sporocytophaga group and violet-pigmented bacteria as indicators for hygienically doubtful drinking water].bacteria of the flexibacter/sporocytophaga group indicate, that drinking water is deficiently protected by the soil covering or may be infiltrated by surface waters. in south bavaria those germs could be demonstrated in 1225 of 3743 samples from central water supplies and in 951 of 1714 samples from decentralized water supplies. f/sp-bacteria could be isolated to a much greater extend from samples which were likewise polluted with escherichia coli, coliforms and colony counts in excess. over the ...19892510750
phospholipid composition of gliding bacteria: oral isolates of capnocytophaga compared with sporocytophaga.the distribution of acetone-soluble (neutral glycolipid) and acetone-insoluble (phospholipid isoprenoids) lipids in oral isolates of gram-negative gliding bacteria of the genus capnocytophaga was compared with those in a non-host-related gliding bacterium, sporocytophaga myxococcoides. the acetone-soluble material accounted for 34 to 55% of the extracted lipids; the remainder was acetone-insoluble material. the major phospholipid was phosphatidylethanolamine (67%), with lesser amounts of lysopho ...1979500209
fatty acid composition of gliding bacteria: oral isolates of capnocytophaga compared with sporocytophaga.the extractable and bound lipids and cellular fatty acids of the gram-negative gliding bacteria, capnocytophaga sputigena, c. gingivalis, and c. ochracea were compared to the non-host-related gliding bacterium sporocytophaga myxococcoides. the extractable lipids represented between 17 and 28% of the cell dry weight, whereas only 2 to 4% of the lipids were in the bound fraction. the methyl esters of the cellular fatty acids were mainly ac15:0, which accounted for 69 to 73% of the total extractabl ...1979500207
sensitivity of cellulolytic bacteria to antibiotics.the sensitivity of eight cellulolytic bacterial strains to eight antibiotics was tested. the results showed that, in general, the strains belonging to cytophaga, cellvibrio, and cellfalcicula are more sensitive to antibiotics than those strains that belong to sporocytophaga and cellulomonas. the inhibitory activity of the tested antibiotics, though differing with different strains, showed the following categories: tetracycline, erythromycin, and chloromycetin were most active, kanamycin, strepto ...1977414477
