氨基寡糖对侧耳菌株发酵液中漆酶活性的影响
Journal of Jilin Agricultural Sciences(2013)
Abstract
研究了在液体木屑培养基中添加0.005、0.01、0.015 mg/mL浓度的氨基寡糖对3株侧耳发酵液中漆酶活性的影响,结果表明:氨基寡糖对侧耳漆酶的产生有明显地促进作用,3株侧耳菌株在氨基寡糖液体木屑培养基中均有漆酶活性,酶活随发酵时间和氨基寡糖浓度而变化,冀微961糙皮侧耳在0.01 mg/mL氨基寡糖浓度,第10 d时漆酶酶活达到最高238 U/mL,比对照增加49.7%。漆酶参与木质素的降解,对木腐菌的生长有着直接的影响,氨基寡糖通过促进漆酶活性,影响侧耳的生长发育。
