Streptomyces nigra sp. nov. Is a Novel Actinobacterium Isolated From Mangrove Soil and Exerts a Potent Antitumor Activity in Vitro.

ABSTRACT: A new bacterial strain, designated 452^T, was isolated from the rhizosphere soil of the mangrove Avicennia marina in China. As determined, its cell wall peptidoglycan contained LL-diaminopimelic acid; MK-9(H8) and MK-9(H6) were the major isoprenoid quinones; and iso-C_16:0 (31.3%), anteiso-C_15:0 (16.9%), and iso-C_15:0 (12.5%) were the major cellular fatty acids (>10.0%). Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain 452^T formed a distinct lineage in the clade of the genus Streptomyces, and was closely related to S. coerulescens DSM 40146^T (99.6% sequence identity), S. bellus DSM 40185^T (99.5%), and S. coeruleorubidus DSM 41172^T (99.3%).
