An amount of psychrophilic bacteria was isolated from deep sea sediment collected from Prydz Bay, Antarctica. The strain AC167, which showed high cold-active chitinase activity, was screened from these bacteria. It was identified as a Pseudomonas species by 16S rDNA sequence comparison.

从南极普里兹湾深海底泥样品中分离得到一批嗜冷细菌，对这些嗜冷细菌进行了产几丁质酶菌株的筛选，对其中一株具有较高产酶活性的菌株AC167所分泌的几丁质酶进行了性质分析，并通过16S rDNA序列分析进行了菌株的分子鉴定。

Psychrophilic and psychro-tolerant bacteria were cultured and used for screening the cold-active enzymes. Some characteristics of cold-active protease and chitinase were analyzed then. Microbial 16S rDNA clone libraries of deep sea sediments were constructed and studied by PCR-RFLP (Restriction Fragment Length Polymorphism) and phylogenetic analysis based on 16S rDNA sequences.
