Mechanism study of novel inducer combinations containing laver powder for <i>Penicillium piceum</i> lignocellulolytic enzyme production

Abstract Inducers play an important role in fungus cellulase production. In this study, a combination of Avicel and laver powder, which contains cellulose, hemicellulose, other polysaccharides, crude lipid, was used to induce lignocellulolytic enzyme production Penicillium piceum H16. When supplemented with various amounts activities or extracellular protein yields increased by 11.4%–102.5%, relative those observed when alone used. particular, filter paper cellobiohydrolase as much 39.3% 102.5%, respectively, after supplementation powder. Furthermore, powder enhanced the efficiency cellulose hemicellulose hydrolysis corn stover 22.2%, respectively. The results suggest that synergistically lignocellulytic P. H16 growth. iTRAQ‐based quantitative proteomics analysis further demonstrate optimized synergistic cocktail from upregulating cellulase‐enhancing factors enzymes. oligosaccharides released may account for induction, help reduce cost producing enzymes filamentous fungi.
