摘要

摘要 甲壳素是地球上最广泛的生物聚合物之一,大量存在于海洋无脊椎动物的外骨骼中。因此,几丁质溶解细菌是海洋生态系统的典型组成部分,在生物降解过程中发挥着重要作用。莫斯科国立大学白海生物站附近的坎达拉沙湾地区栖息着大量无脊椎动物,是分离此类细菌的理想地点。研究人员测定了环境原核生物群落和甲壳素富集培养物的组成,并分离出活性甲壳素溶解菌的纯培养物,经鉴定为假交替单胞菌(Pseudoalteromonas undina)和藻溶弧菌(Vibrio alginolyticus)。对富集培养物中主要菌属的几丁质分解潜力进行了评估;这些菌属可能包括以前未知的几丁质分解微生物。

Chitin Degradation by Microbial Communities of the Kandalaksha Bay, White Sea

Abstract

Chitin is one of the most widespread biopolymers on Earth and occurs in high quantities in the exoskeletons of marine invertebrates. Chitinolytic bacteria are therefore typical components of marine ecosystems and play an important part in biodegradation. The Kandalaksha Bay area near the White Sea Biological Station, Moscow State University, which is inhabited by numerous invertebrates, is a promising site for the isolation of such bacteria. The composition of environmental prokaryotic communities and enrichment cultures grown on chitin was determined, and pure cultures of active chitinolytics were isolated and identified as Pseudoalteromonas undina and Vibrio alginolyticus. The chitinolytic potential of the genera predominant in enrichment cultures was assessed; these may include previously unknown chitinolytic microorganisms.
