Abstract

Extracellular peptidoglycan is commonly found in natural environments, yet little is known about its biodegradation in nature. We here describe a novel peptidoglycan-degrading bacterium, designated strain 332, isolated from mesotrophic lake water in Denmark. The strain was a Gram-negative-staining, motile rod. It had chitinase and lysozyme activities, which are relevant to peptidoglycan degradation, and was capable of utilizing several mono- and disaccharides, amino acids and organic acids. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain 332 belonged to the genus . Fatty acids of the strain included C and C, which are characteristic of the genus . The DNA G+C content of the strain was 65.3 mol%. A DNA–DNA hybridization value of 66.2 % was found between strain 332 and DSM 17581. Based on differences in physiological and biochemical characteristics, the strain is considered to represent a novel species, for which the name sp. nov. is proposed. The type strain is 332 (=DSM 21246 =LMG 24775). An emended description of is also presented.
