Abstract

Anaerobically grown bacteria isolated from the hindgut contents of the termites Coptotermes lacteus (Froggatt), Mastotermes darwiniensis Froggatt and Nasutitermes exitiosus (Hill) were nitrogenase-positive as assayed by acetylene reduction. Nitrogen fixation, confirmed with 15N2, was highest in the isolate from M. darwiniensis. All isolates were identified as Citrobacter freundii (Braak) Werkman & Gillen.

摘要

从乳白蚁（Coptotermes lacteus，弗罗加特）、达尔文澳白蚁（Mastotermes darwiniensis，弗罗加特）和毁灭鼻白蚁（Nasutitermes exitiosus，希尔）后肠内容物中分离出的厌氧生长细菌，经乙炔还原法测定为固氮酶阳性。用15N2证实的固氮作用在来自达尔文澳白蚁的分离物中最高。所有分离物均被鉴定为弗氏柠檬酸杆菌（Citrobacter freundii，布拉克）韦克曼和吉伦。
