Abstract
Two strains designated RF6(T) and RB10(T) were isolated, from activated sludge and from river sediments, respectively, both systems receiving chromium contaminated water. Phylogenetic analysis showed that strain RF6(T)and strain RB10(T) represented two new species of the genus Leucobacter. Strain RB10(T) can be distinguished from RF6(T) by its ability to grow at 37 degrees C, by showing a different optimum pH, by cell wall amino acids different relative amount and by having the fatty acid strait C16:0 as the third most abundant fatty acid. On the basis of the distinct peptidoglycan composition, 16S ribosomal DNA sequence analysis, DNA-DNA reassociation values, and phenotypic characteristics we are of the opinion that strain RF6(T) represents a new species of the genus Leucobacter for which we propose the name Leucobacter luti (CIP 108818(T)=LMG 23118) and that strain RB10(T) represents an additional new species of the same genus for which we propose the name Leucobacter alluvii (CIP 108819(T)=LMG 23117).Entities:
