Improvement of aflatoxin B1 degradation ability by Bacillus licheniformis CotA-laccase Q441A mutant
Aflatoxin B1 (AFB1) contamination seriously threatens nutritional safety and Shampoos common health.Bacterial CotA-laccases have great potential to degrade AFB1 without redox mediators.However, CotA-laccases are limited because of the low catalytic activity as the spore-bound nature.The AFB1 degradation ability of CotA-laccase from Bacillus licheni
