Flavobacterium lindanitolerans sp. nov., isolated from hexachlorocyclohexane-contaminated soil.

A Gram-negative, non-spore-forming, cream-yellow-pigmented bacterial strain, IP-10(T), was isolated from soil samples from a waste site highly contaminated with hexachlorocyclohexane in Ummari village, India. The organism showed the highest 16S rRNA gene sequence similarity of 92.7 % with Flavobacterium soli KCTC 12542(T) and levels of 87-92 % with the type strains of other recognized species of the genus Flavobacterium. The DNA G+C content of strain IP-10(T) was 31 mol%. The predominant fatty acids were iso-C(15 : 0) (22.1 %), iso-C(17 : 0) 3-OH (18.5 %) and summed feature 3 (comprising C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH; 13.2 %). Strain IP-10(T) could be differentiated from recognized species of the genus Flavobacterium based on a number of phenotypic features. Strain IP-10(T) is therefore considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium lindanitolerans sp. nov. is proposed. The type strain is IP-10(T) (=MTCC 8597(T)=CCM 7424(T)).
