Streptomyces anthophorae sp. nov. and Streptomyces nidicola sp. nov., novel actinobacteria isolated from a solitary bee

Six novel actinobacterial strains (BH034 T , BH055, BH097, BH104, BH105 and BH106 T ) were isolated from developing brood in nests of the solitary bee species Anthophora bomboides from Bodega Bay, California, USA. Phylogenetic analysis based on a five-gene multilocus sequence alignment and whole-genome data positions all six strains within the genus Streptomyces , with close relation to Streptomyces endophyticus YIM 65594 T and Streptomyces fractus MV32 T . Through genetic and chemotaxonomic analysis, five of the isolates (BH034 T , BH055, BH097, BH104 and BH105) were found to be a clade representing one species [>96% average nucleotide identity (ANI)], whereas BH106 T was a distinct species (
