Abstract:With the development and utilization of marine resources，the value of edible sea cucumber has attracted more and more attention. Based on the depositional feeding properties of sea cucumber，intestinal microbes assume the exchange of environmental nutrients inside and outside sea cucumber. Therefore，the detailed study of the intestinal flora of sea cucumber is very valuable，but at present，there are few reports on the intestinal flora of sea cucumber in marine environment at home and abroad，which has some limitations for scholars to carry out research. On the basis of summarizing the existing literature reports of sea cucumber and refining the composition，influencing factors and related functions of its intestinal flora，this paper aimed to provide more theoretical reference for the subsequent development and utilization of intestinal flora of sea cucumber.
