Abstract
A Gram-stain-positive bacterium, designated TSL3T, was isolated from faeces of a porcupine, Hystrix indica, from the Budapest Zoo and Botanical Garden, Hungary. On the basis of 16S rRNA gene sequence analysis, the strain is phylogenetically related to the family Micrococcaceae. The highest 16S rRNA gene sequence similarity was found with Micrococcus terreus V3M1T (96.50 %) followed by Arthrobacter humicola KV-653T (96.43 %). Cells of strain TSL3T were aerobic, non-motile and coccoid-shaped. The main fatty acids were anteiso-C15 : 0 (54.4 %), iso-C16 : 0 (18.2 %) and iso C15 : 0 (9.7 %). The major menaquinone was MK-7, and the polar lipid profile included phosphatidylglycerol, diphosphatidylglycerol, dimannosylglyceride, trimannosyldiacylglycerol, phosphatidylinositol, three unknown phospholipids and two unknown glycolipids. Strain TSL3T showed the peptidoglycan structure A4alpha l-Lys - Gly - l-Glu. The DNA G+C content of strain TSL3T was 58.4 mol%. Phenotypic and genotypic characterisation clearly showed that strain TSL3T could be differerentiated from the members of other genera in the family Micrococcaceae. According to these results, strain TSL3T represents a novel genus and species, for which the name Micrococcoides hystricis gen. nov., sp. nov. is proposed. The type strain is TSL3T (=DSM 29785T=NCAIM B. 02604T).
