Chelatococcus composti sp. nov., isolated from penicillin fermentation fungi residue with pig manure co-compost

Abstract

A novel Gram-stain-negative bacterium, designated strain PC-2^T, was isolated from penicillin fermentation fungi residue with pig manure co-compost in China. Phylogenetic analysis, based on 16S rRNA gene sequence comparisons, revealed that strain PC-2^T should be assigned to the genus Chelatococcus and that it had 98.9 % similarity with Chelatococcus daeguensis, 98.8 % with Chelatococcus sambhunathii, 98.4 %, with Chelatococcus caeni and 96.0 % with Chelatococcus asaccharovorans. The G+C content of genomic DNA was 70.9 mol%. On the basis of the phylogenetic analysis, DNA-DNA relatedness values, phenotypic characteristics and chemotaxonomic data, strain PC-2 ^T represents a novel species of the genus Chelatococcus, for which the name Chelatococcus composti sp. nov. is proposed. The type strain is PC-2^T (=DSM 101465^T=CGMCC 1.15283^T).
