BACKGROUND Microbial consortia represent promising candidates for aiding in the development of plant biomass conversion strategies for biofuel production. However, the interaction between different community members and the dynamics of enzyme complements during the lignocellulose deconstruction process remain poorly understood. We present here a comprehensive study on the community structure an...

Volvariella volvacea, commonly known as the straw or paddy mushroom, had the following growth characteristics: minimum temperature, 25 degrees C; optimal temperature, 37 degrees C; maximal temperature, 40 degrees C; pH optimum 6.0. Optimal pH for cellulase production was 5.5. The optimal initial pH for cellulase production and mycelial growth was found to be 6.0. The pH and temperature optima f...

Lignocellulolytic white-rot fungi allow the bioconversion of agricultural wastes into value-added products that are used in a myriad applications. The aim this work was to use corn residues (Zea mays L.) produce valuable under solid-state fermentation (SSF) with Pleurotus ostreatus. White-rot fungus P. ostreatus isolated from maize silage (MS) and thereafter it inoculated on MS as substrate com...

Sterol regulatory element binding proteins (SREBPs) are conserved from yeast to mammalian cells and function in the regulation of sterol homeostasis. In fungi, the SREBP pathway has been implicated in the adaptation to hypoxia and in virulence. In Neurospora crassa and Trichoderma reesei, the SREBP pathway also negatively regulates protein secretion under lignocellulolytic conditions. Here we u...

Neurospora crassa colonizes burnt grasslands in the wild and metabolizes both cellulose and hemicellulose from plant cell walls. When switched from a favored carbon source such as sucrose to cellulose, N. crassa dramatically upregulates expression and secretion of a wide variety of genes encoding lignocellulolytic enzymes. However, the means by which N. crassa and other filamentous fungi sense ...

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%, re...

Lentinula edodes has traditionally been grown on fallen logs. It produces a wide array of enzymes to digest the lignocellulolytic substrate for nutrients. Thus, this organism represents a rich source of potentially potent lignocellulolytic enzymes that can be harnessed for conversion of biomass to simple sugars. These sugars can then be used as feedstock for ethanol production or other chemical...
