Non-pathogenic forms are often used in the biotechnology sector, including Bacillus subtilis. Pulvinate elevation. Diversity of the growth patterns of Bacillus subtilis colonies on agar As mentioned, Bacillus licheniformis is commonly found on bird feathers; by fermentation with B. licheniformis, the large amounts of non-digestible proteins found in the feathers can turn into a feather meal for livestock. In addition to the oxidative degradation of zearalenone (ZEN) and aflatoxin B1 (AFB1), CotA laccase also has the ability to degrade the Alternaria toxin alternariol (AOH). FIG. FIG.
