Spirosoma lacussanchae sp. nov., a phosphate-solubilizing bacterium isolated from a freshwater reservoir.

A phosphate-solubilizing bacterium, designated CPCC 100624T, was isolated from a freshwater reservoir in south-west China. The 16S rRNA gene sequence comparison of strain CPCC 100624T with the available sequences in the GenBank database showed that the isolate was closely related to members of the genus Spirosoma. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 100624T formed a stable phylogenetic subclade with Spirosoma soli MIMBbqt12T within the genus Spirosoma, which indicated that strain CPCC 100624T could be identified as a member of the genus Spirosoma.
