Borate-treated food affects survival, vitamin B12 content, and digestive processes of subterranean termites
1990 - IRG/WP 1448
Toxicity of boron compounds was studied by analyzing survival rates and vitamin B12 contents in Formosan subterranean termites, Coptotermes formosanus Shiraki, that were exposed to dietary treatments for 10 days. The dietary treatments applied in moistened cellulose were (a) 0.05% boric acid equivalent (BAE) of disodium octaborate tetrahydrate, (b) 0.05% BAE of anmonium pentaborate plus sodium sul...

A study of methanogenesis and sulphate-reduction: A possible source of explosive gas mixtures in a gold mine
1989 - IRG/WP 1399
Previous work isolated anaerobic bacteria from timbers and drainage water in a gold mine. The present work identifies the predominant methanogen in the mine ecosystem as Methanobacterium bryantii and sulphate-reducing isolates as Desulphovibrio desulphuricans and Desulphotomaculum antarcticum. Laboratory studies using model systems evaluate the activity of methanogenic and sulphate-reducing bacter...
