Aspartic peptidase made little contribution on the formation of NH3-N and AA-N. degradation of protein into peptides was attributed to aspartic-and cysteine peptidases.

天冬氨酸蛋白酶在氨态氮和游离氨基酸的形成过程中，贡献率最小；在将蛋白水解成肽氮的过程中，天冬氨酸蛋白酶和半胱氨酸蛋白酶起到了主要作用。

Although these ammonia producers have limited ability to degrade proteins, they can utilize peptides or amino acids released by the proteases and peptidases of other ruminal bacteria.

虽然这些产氨菌不能有效地降解蛋白质，但它们可以利用其他瘤胃细菌的蛋白酶或肽酶水解的产物小肽与氨基酸。
