The invention discloses lactobacillus amylovorus for producing feruloyl esterase. Named as (lactobacillus amylovorus)c, the bacterial strain is preserved in China General Microbiological Culture Collection Center on July 6th, 2015 with the preservation number of CGMCC No.11056. Tests show that lactobacillus amylovorus can produce amylase when growing in a starch-containing culture medium and can produce feruloyl esterase when growing in an ethyl-ferulate-containing culture medium, that is, lactobacillus amylovorus has a potential application value in paper-making, textile, food, cosmetics and pharmaceutical industries, particularly, a lactobacillus amylovorus fermented silage can improve the content of lactic acid by 8%, reduce the pH value by 0.27 and shorten the fermentation period by 15 days, and lactobacillus amylovorus has a wide application prospect in preparation of fermented silages and other microecologics.
