Abstract

Nitrogen-fixing activity of microorganisms in the intestines of Crane fly (Tipulidae) larvae and their influence on the processes of microbial nitrogen fixation in soil have been studied. Two independent methods have shown high rates of nitrogenase activity in the digestive tract of larvae, which is determined mainly by transit nitrogen-fixing microorganisms. Nitrogen fixers actively developing in the intestines of larvae stimulate a sharp increase in nitrogenase activity in the soil: after 3 months of incubation, the activity increases eightfold; it can contribute to the accumulation of nitrogen in the habitats of the larvae.

ul虫肠道中的微生物固氮

摘要

研究了白鹤蝇幼虫肠道中微生物的固氮活性及其对土壤中微生物固氮过程的影响。两种独立的方法显示出幼虫消化道中高水平的固氮酶活性，这主要是由固氮转运微生物决定的。在幼虫肠道中积极生长的固氮剂会刺激土壤中固氮酶的活性急剧增加：培养3个月后，活性增加了8倍。它可以促进幼虫栖息地中氮的积累。
