  • Publication number: 20110171722
    Abstract: The present invention discloses an isolated pure culture of a novel strain CK1 of Bacillus licheniformis, BCRC 910458, capable of detoxification of zearalenone (ZEN). Using physiological, biochemical, morphological identification and 16S rRNA gene sequence analysis methods, the strain CK1 was identified as Bacillus licheniformis. Through extracellular xylanase, CMCase protease assays and evaluations for zearalenone detoxification, the strain CK1 strain was identified to possess good ZEN-detoxifying ability, to be non-hemolytic, non-enterotoxin producing, and displayed high levels of extracellular xylanase, cellulase, and protease activities. Accordingly, Bacillus licheniformis CK1 can be applied as food and feed supplement for bio-detoxification of ZEN.
