Planctopirus hydrillae sp. nov., an antibiotic producing Planctomycete isolated from the aquatic plant Hydrilla and its whole genome shotgun sequence analysis.

An antibiotic producing novel Planctomycete strain, designated JC280, was isolated from the surface of the plant Hydrilla verticillata collected from an alkaline lake (Buffalo lake), University of Hyderabad, Hyderabad, India. The morphological and chemotaxonomic properties of strain JC280 were in agreement with the characteristics of the genus Planctopirus. The cell shape was spherical to ovoid and some were tear drop shaped.

Streptosporangium terrae sp. nov., a novel actinomycete isolated from the rhizosphere of Callistemon citrinus (Curtis), India.

A novel actinomycete strain, designated VRC21(T), was isolated from the rhizosphere of Callistemon citrinus collected from Hyderabad, India. The morphological and chemotaxonomic properties of strain VRC21(T) was consistent with the characteristics of members of the genus Streptosporangium, that is, the formation of sporangia on aerial mycelium, coiled unbranched hyphae within the spore vesicle, the presence of meso-diaminopimelic acid in the cell wall, and madurose and galactose as major whole-cell sugars. Diagnostic polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol-mannosides.

Saccharopolyspora indica sp. nov., an actinomycete isolated from the rhizosphere of Callistemon citrinus (Curtis).

A novel actinomycete strain, designated VRC122T, was isolated from a Callistemon citrinus rhizosphere sample collected from New Delhi, India, and its taxonomic status was determined by using a polyphasic approach. Strain VRC122T was a Gram-stain-positive, aerobic, non-motile, non-acid-alcohol-fast strain. Phylogenetic analysis based on 16S rRNA gene sequences showed the strain was placed in a well-separated sub-branch within the genus Saccharopolyspora.

Nocardia bhagyanesis sp. nov., a novel actinomycete isolated from the rhizosphere of Callistemon citrinus (Curtis), India.

A novel actinomycete strain, designated VRC07(T), was isolated from a Callistemon citrinus rhizosphere sample collected from Hyderabad, India. Its taxonomic status was determined by using polyphasic approach. It is a Gram-positive, aerobic, non-motile, weakly acid-fast strain.
