Novel heliobacteria of a few semi-arid tropical soils.


ABSTRACT: Out of forty rhizosphere soils collected from semi arid tropical regions of Andhra Pradesh, India, 30 gave positive enrichments for heliobacteria. These bacteria were recognized by the presence of bacteriochlorophyll-g together with endospores in the initial enrichments. Using group specific primers of 16S rRNA gene, ten monoheliobacterial cultures were sequenced. They were finally grouped into 3 clusters based on the 16S rRNA gene similarity. Based on a few phenotypic characters, in addition to genetic characterization, we identified them as potential novel species and the 16S rRNA gene sequences were deposited with EMBL.
