摘要
Eleven Bacillus subtilis strains capable of producing protease were isolated from fermented foods and characterized. B. subtilis DB and SR were selected for digesting rice proteins. It was found that they could reduce rice allergenicity by hydrolyzing allergenic fragments detected by immunoblotting. Moreover, the fact that B. subtilis SR could also digest rice proteins resulted in the increase of glutamic acid, which is the important amino acid for gamma-aminobuityric acid (GABA) production. Therefore, B. subtilis SR has the potential for application in the production of hypoallergenic fermented rice-noodle with high nutrient availability.
