FLAVOBACTERIUM DEVORANS ATCC 10829: A STRAIN OF PSEUDOMONAS PAUCIMOBILIS

Abstract

F. devorans ATCC 10829 (= NRRL B-54 = KM 1367) was compared with P. 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, EM and visible absorption spectrum of yellow pigments in acetone extracts of bacterial cells. The long-chain base component of ceramide glucuronic acid in cellular lipids was quantitatively determined from TLC of hexane-ether extract from the hydrolysate of acetone-dried cells of 4 strains. The characteristic profile of cellular fatty acids of strain 10829, and 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 DNA, F. devorans 10829 was reidentified as a strain of P. paucimobilis. Since the strain ATCC 10829 was a misidentified organism, the name F. devorans can not be a senior synonym over P. paucimobilis. Unless the authentic strain of the original describer of F. devorans or any isolate in conformity with the original description for the species is found, the name F. devorans should not be retained.
