( 2011 ) also used a microbial protease to obtain peptides with antimicrobial activity; however, those peptides were only able to inhibit the growth of two Gram-positive bacterial strains ( Bacillus cereus ATCC 9634 and Corynebacterium fimi NCTC 7547) using a much higher concentration (250 mg/mL) than that used in the present work.
