Note: Values are as mean ± standard deviation, n = 20. The significance analysis used in same enzyme and cultivation mode between different tissues with the letter. The capital superscript letters in the some row represent the significant difference (P < 0.01); the superscript lowercase letters represent difference (P < 0.05); and there are no differences with same letter (P > 0.05). The significance analysis used in same tissue and enzyme between different cultivation modes with *. ** represent the significant difference (P < 0.01), *represent difference (P < 0.05)
