FLAVOBACTERIUM-DEVORANS ATCC-10829 - STRAIN OF PSEUDOMONAS-PAUCIMOBILIS

Flavobacterium devorans ATCC 10829 (=NRRL B-54=KM 1367) was compared with Pseudomonas paucimobilis NCTC 11030 (type, =KM 2395), 11031 (=KM 2396), and 11032 (=KM 2397) in respect to more than 65 phenotypic tests, susceptibility to 15 antimicrobial agents, electron-microscopy, and visible absorption spectrum of yellow pigments in acetone extracts of bacterial cells. Long-chain base component of ceramide glucuronic acid in cellular lipids was quantitatively determined from thin-layer chromatogram of hexane-ether extract from the hydrolysate of acetone-dried cells of 4 strains. Characteristic profile of cellular fatty acids of strain 10829, as well as of 3 P. Paucimobilis strains, was the presence of 2-hydroxymyristic acid, palmitic acid, and octadecenoic acid in high concentration. Because of the phenotypic and analytical similarities and high percentage of guanine plus cytosine content in deoxyribonucleic acid, F. Devorans 10829 was reidentified as a strain of P. Paucimobilis. Since the strain ATCC 10829 was a misidentified organism, the name Flavobacterium devorans can not be a senior synonym over Pseudomonas paucimobilis. Unless the authentic strain of the original describer of F. Devorans or any isolate in conformity with the original description for the species were found, the name Flavobacterium devorans should not be retained further. © 1979, Applied Microbiology, Molecular and Cellular Biosciences Research Foundation.
