摘要:

为了进一步了解生物絮团的本质,促进生物絮团技术的发展与应用,本文从生物絮团的功能、生物絮团的结构和生物絮团的人工调控等三个层次进行了分析,得出可通过改变碳源类型、碳氮比、温度、pH和溶解氧等条件,实施对养殖水体微生物群落结构的人工调控,从而达到净化养殖水体、实现养殖对象的生物防治和提高饲料利用率等目标。并指出生物絮团中微生物菌群间相互作用和种属动态变化及其精准调控仍有待深入研究。

关键词: 水产养殖, 生物絮团, 微生物群落, 功能与结构, 人工调控

Abstract:

To further explore the nature of the biofloc, and promote the development and application of the biofloc technology, this paper analyzes the three aspects of the biofloc: the function, the structure and the artificial regulation. It is concluded that an artificial regulation of the microbial community structure in the aquacultural water can be achieved by the condition adjustment, such as carbon source type, carbon-nitrogen ratio, temperature, pH, dissolved oxygen and etc., so as to attain the purification of the aquacultural water, the biocontrol of the aquacultural species and the improvement of feed utilization rate. And it is pointed out that the interaction among the microflora and the dynamic changes of species and its precise regulation should be studied more deeply.

Key words: aquaculture, biofloc, microbial community, structure and function, artificial regulation
