An alkaliphilic, slightly halotolerant, chemo-organotrophic, Gram-positive, rod-shaped bacterium, strain 69B4T, was isolated from the sediment of the littoral zone of Lake Bogoria, Kenya. Phylogenetically, it is a member of the genus Cellulomonas, showing less than 97·5 % sequence similarity to the type strains of other Cellulomonas species. The highest level of similarity, albeit moderate, was found with respect to Cellulomonas cellasea DSM 20118T. Chemotaxonomic properties confirm the 16S rRNA gene-based generic affiliation, i.e. a DNA G+C content of 71·5 mol%, anteiso-C15 : 0 and C16 : 0 as the major fatty acids, MK-9(H4) as the major isoprenoid quinone, a peptidoglycan containing L-ornithine as the diamino acid and D-aspartic acid in the interpeptide bridge and phosphatidylglycerol as the only identified main polar lipid. The strain is aerobic to facultatively anaerobic, being capable of growth under strictly anaerobic conditions. Optimal growth occurs between pH values 9·0 and 10·0. On the basis of its distinct phylogenetic position and metabolic properties, strain 69B4T represents a novel species of the genus Cellulomonas, for which the name Cellulomonas bogoriensis sp. nov. is proposed. The type strain is 69B4T (=DSM 16987T=CIP 108683T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 69B4T is X92152.
