<P><B>Abstract</B></P> <P>The synthesis of cellulase in filamentous fungi can be triggered by several inducers. In this study, a bamboo-shoot shell pretreated with <I>Pleurotus ostreatus</I> could promote the formation of cellulases in <I>Aspergillus niger</I>. 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.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Pretreatment with <I>P. ostreatus</I> could promote the production of cellulases. </LI> <LI> Bamboo-shoot shell could be converted into soluble inducer of cellulases. </LI> <LI> The inducer maybe a lignin derivative without aromatic ring. </LI> <LI> The revelation is useful for cellulase industry. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
