The isolate was cultivated in continuous culture in a bench top fermenter in Medium 98-5 amended with an increasing amount of mimosine for 16 days. Degradation of mimosine was determined with a colorrinetfic method Incubated at 39 ℃ under anaerobic conditions, the isolate showed complete degradation of mimosine within one ~veek. The bacteriological pure isolate is an aero-tolerant gram-negative cocco-bacillus. By DNA sequencing analysis it belongs to genus Klebsiella. It was multiplied hi brain-heart-infusion, entrapped in alginate, and dried （37 ℃）. Feeding trials in sheep in Myalmlar showed complete innocuity＇ and complete detoxification of mimosine from leucaena leaves.展开更多
