Through preliminary and secondary screening,a strains with high enzyme activity which could produce feruloyl esterase was screened out from Fu-brick tea,according to its individual and colony characteristics,it was identified as Eurotium cristatum. Feruloyl esterase enzyme activity was used as measurable indicator,water content,inoculums-size,temperature and time was chosen as variables,the solid-state fermentation conditions of chosen Eurotium cristatum were optimized. The results showed that black primarytea the optimal condition was 1‰ inoc...
