sp. nov., an indole acetic acid-producing actinobacterium isolated from cow dung.

A novel growth-promoting and indole acetic acid-producing strain, designated NEAU-LLB, was isolated from cow dung collected from Shangzhi, Heilongjiang Province, PR China. Cells of strain NEAU-LLB were Gram-stain-positive, non-motile, aerobic and non-spore-forming. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain NEAU-LLB belonged to the genus .

Microbacterium helvum sp. nov., a novel actinobacterium isolated from cow dung.

A Gram-positive, aerobic, non-motile, non-spore-forming, short rod-shaped strain, NEAU-LLC, was isolated from cow dung in Shangzhi City, Heilongjiang Province, Northeast China and identified by a polyphasic taxonomic study. Colonies was light yellow, round, with entire margin. Strain NEAU-LLC was grown at 15-45 ℃ and pH 6.

sp. nov., an actinobacterium isolated from cow dung.

A novel actinobacterium, designated strain NEAU-351, was isolated from cow dung collected from Shangzhi, Heilongjiang Province, northeast PR China and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-351 belonged to the genus , with the highest similarity (98.96 %) to DSM 44801 and less than 98.
