Zearalenone (ZEN) is a non-steroidal estrogen produced by many Fusarium species in cereals and other plants, and is frequently implicated in safety of foods and feeds. A ZEN-degrading microorganism has been isolated and identified as a Bacillus subtilis subspecies. It degraded 99% ZEN (1 mg kg(-1)) in liquid medium after 24 h and more than 95% of ZEN (0.25 mg kg(-1)) could be degraded after 48 h in a solid-state fermentation. This isolate can thus be used to decontaminate raw materials, like grains, to reduce the mycotoxin concentration.

A family of SERINE ENDOPEPTIDASES isolated from Bacillus subtilis. EC 3.4.21.-
A species of gram-positive bacteria that is a common soil and water saprophyte.
A cyclic polypeptide antibiotic isolated from culture filtrates of Bacillus subtilis that acts as an antifungal agent.
A serine endopeptidase isolated from Bacillus subtilis. It hydrolyzes proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. It also hydrolyzes peptide amides. (From Enzyme Nomenclature, 1992) EC 18.104.22.168.
A complex of cyclic peptide antibiotics produced by the Tracy-I strain of Bacillus subtilis. The commercial preparation is a mixture of at least nine bacitracins with bacitracin A as the major constituent. It is used topically to treat open infections such as infected eczema and infected dermal ulcers. (From Goodman and Gilman, The Pharmacological Basis of Therapeutics, 8th ed, p1140)
