Enhancement of Lignin Peroxidase and Manganese Peroxidase Production by Humicola Grisea in a Tubular Air-lift Fermenter
ثبت نشده
چکیده
Abstrak: Penghasilan enzim lignin peroksidase (LiP) dan mangan peroksidase (MnP) oleh Humicola grisea di dalam fermenter angkut udara diselidiki. Penghasilan optimum parameter yang digunakan pada fermenter ini ialah kadar pengudaraan 1.0 vvm, 1.0% (b/i) glukosa, 10.5 mM (NH4)2HPO4 dan kepekatan inokulum 1.0% (i/i; 6 × 10 spora/ml). Peningkatan sebanyak 52% dalam penghasilan LiP dan 49% dalam MnP diperoleh selepas semua parameter dioptimumkan.

Determination of lignin-modifying enzymes (LMEs) in Hyphodermella species using biochemical and molecular techniques
White-rot basidiomycetes are one of the most important lignolytic microorganisms. These fungi have been reported to secrete three main classes of lignin degrading enzymes: lignin peroxidases (LiPs), manganese peroxidases (MnPs) and laccases. In this study, for the first time the lignin degrading capability of two plant pathogens i.e. Hyphodermella rosae and H. corrugata was evaluated using both...
متن کاملPhysiological Peculiarities of Lignin-Modifying Enzyme Production by the White-Rot Basidiomycete Coriolopsis gallica Strain BCC 142
Sixteen white-rot Basidiomycota isolates were screened for production of lignin-modifying enzymes (LME) in glycerol- and mandarin peel-containing media. In the synthetic medium, Cerrena unicolor strains were the only high laccase (Lac) (3.2-9.4 U/mL) and manganese peroxidase (MnP) (0.56-1.64 U/mL) producers while one isolate Coriolopsis gallica was the only lignin peroxidase (LiP) (0.07 U/mL) p...
متن کاملOverproduction of lignin-degrading enzymes by an isolate of Phanerochaete chrysosporium.
Phanerochaete chrysosporium is a white rot fungus which secretes a family of lignin-degrading enzymes under nutrient limitation. PSBL-1 is a mutant of this organism that generates the ligninolytic system under nonlimiting conditions during primary metabolism. Lignin peroxidase, manganese peroxidase, and glyoxal oxidase activities for PSBL-1 under nonlimiting conditions were 4- to 10-fold higher...
متن کاملLignolytic and lignocellulosic enzymes of Ganoderma lucidum in liquid medium
Lignin is probably one of the most recalcitrant compounds synthesized by plants. This compound is degraded by few microorganisms. White-rot fungi have been extensively studied due to its powerful ligninolytic enzymes. Ganoderma lucidum is one such organism that can degrade lignin and hence it was isolated and screened qualitatively by guaiacol plate assay. Spectrophotometric enzyme assays were ...
متن کاملLignin-Degrading Enzymes of the Commercial Button Mushroom, Agaricus bisporus.
Agaricus bisporus, grown under standard composting conditions, was evaluated for its ability to produce lignin-degrading peroxidases, which have been shown to have an integral role in lignin degradation by wood-rotting fungi. The activity of manganese peroxidase was monitored throughout the production cycle of the fungus, from the time of colonization of the compost through the development of f...
