Fig. 2From: Comparative studies of versatile extracellular proteolytic activities of lactic acid bacteria and their potential for extracellular amino acid productions as feed supplementsExtracellular proteolytic activity of LAB isolates at pH 5, pH 6.5 and pH 8. Values are mean ± standard error mean (SEM), n = 3. Vertical bars represent SEM. Values bearing different capital letter alphabets (A-F) among bacteria isolates are significant different (P < 0.05) while values sharing different small letter alphabet (a-c) among various pH are significant different (P < 0.05)Back to article page
