Serratia bozhouensis sp. nov., Isolated from Sewage Samples of a Dairy Farm

Abstract

A Gram-negative, rod-shaped, salt-tolerant, non-pigmented, and non-spore-forming bacterium, designated strain W1^T (type strain CICC 23797 = CGMCC1.14949), was isolated from sewage samples of a dairy farm in Bozhou, Anhui, China. Strain W1 was resistant to lincomycin, troleandomycin, rifamycin, and vancomycin. Sequence analysis of the 16S rDNA gene revealed that the strain showed sequence similarity of 98.2% with the closest related species Serratia quinivorans CP6a^T. The genomic DNA G+C content of the isolate was 52.8 mol%. The biochemical characteristics of strain W1^T assessed by the API 20E and Biolog GEN III analysis were different from those of the members of the genus Serratia. On the basis of the phenotypic and genotypic differences, strain W1 was proposed to be a novel Serratia species, Serratia bozhouensis sp. nov W1^T.
