Patent number: 5852054Abstract: A biocontrol bacteria, Bacillus cereus ATCC 53522, has been found to naturally synthesize two antibiotics, here designated zwittermicin A and antibiotic B. Zwittermicin A is a 396 dalton linear aminopolyol, a class of metabolite previously unknown in B. cereus. Antibiotic B is an aminoglycoside. Both antibiotics exhibit inhibitory activity on many fungal and bacterial pathogens.Type: GrantFiled: March 8, 1994Date of Patent: December 22, 1998Assignee: Wisconsin Alumni Research FoundationInventors: Jo Handelsman, Laura Silo-Suh, Jon Clardy, Haiyin He
