| Summary: | Higher nitrogen fixation activity was exhibited by the workers of the oriental termite Coptotermes formosanus Shiraki. The nitrogen-fixing activity of the newly collected workers was about 0.0944 μg/g·h<sup>-1</sup>. Nitrogen content of food and physiological status of the termite affected its nitrogen fixation activity, and some bactericides abolished it. Two facultative nitrogen-fixing anaerobes isolated from the gut of termites, designated as strain HN1 and strain YN, were identified as Citrobacter sp. Both Strains showed nitrogen-fixing activity under anaerobic condition. The number of nitrogen-fixing cells in each termite gut was estimated as about 7 500 based on the most probable number method. |
