丝状真菌中纤维素酶的合成可以由几种诱导剂触发。在本研究中，平菇预处理的竹笋壳能促进黑曲霉纤维素酶的形成。UPLC-TOF-MS、超滤、FT-IR等进一步鉴定表明，该可溶性诱导剂不是传统的双糖，而是一种改性的木质素聚合物。这一发现可能导致改进纤维素酶生产率的初步策略。
The synthesis of cellulase in filamentous fungi can be triggered by several inducers. In this study, a bamboo-shoot shell pretreated withPleurotus ostreatuscould promote the formation of cellulases inAspergillus niger. Further identification, including UPLC-TOF-MS, ultrafiltration, and FT-IR, denoted that the soluble inducer was not a traditional disaccharide but a type of modified lignin polymer. This revelation may result in incipient strategies to ameliorate cellulase productivity.
