mediated biosynthesis of nanoparticles and biofortification.

Unlabelled: The mycosynthesis of biogenic NPs using nanotechnology technique is an ecofriendly and economical approach. The extracellular mycelial extract of the fungi were used to biosynthesized Zn, Cu and Fe NPs using zinc sulphate, zinc chloride, copper sulphate, copper chloride ferrous sulphate and ferric chloride, precursor salts at 1.0 mM concentration.

Comparative assessment on lignocellulose degrading enzymes and bioethanol production from spent mushroom substrate of Calocybe indica and Volvariella volvacea.

In the current study, we compared the production of extracellular lignocellulose degrading enzymes and bioethanol from the spent mushroom substrate (SMS) of Calocybe indica and Volvariella volvacea. From SMS at different stages of the mushroom development cycle, ligninolytic and hydrolytic enzymes were analysed. The activities of lignin-degrading enzymes, including lignin peroxidase (LiP), laccase, and manganese peroxidase (MnP) were maximal in the spawn run and primordial stages, while hydrolytic enzymes including xylanase, cellobiohydrolase (CBH), and carboxymethyl cellulase (CMCase) showed higher activity during fruiting bodies development and at the end of the mushroom growth cycle.

Application of ligninolytic potentials of a white-rot fungus Ganoderma lucidum for degradation of lindane.

Lindane, a broad-spectrum organochlorine pesticide, has caused a widespread environmental contamination along with other pesticides due to wrong agricultural practices. The high efficiency, sustainability and eco-friendly nature of the bioremediation process provide an edge over traditional physico-chemical remediation for managing pesticide pollution. In the present study, lindane degradation was studied by using a white-rot fungus, Ganoderma lucidum GL-2 strain, grown on rice bran substrate for ligninolytic enzyme induction at 30 °C and pH 5.

Molecular characterization of shiitake medicinal mushroom, Lentinus edodes strains (higher Basidiomycetes) using RAPD and ITS sequencing.

The molecular phylogeny in seven strains of Lentinus edodes was studied based on RAPD and their internal transcribed spacers (ITS) regions. The strains were analyzed by RAPD with 20 arbitrary primers. Fifteen primers were found efficient for the amplification of the genomic DNA.
