Production , Purification and Properties of Extracellular Laccase of Agaricus bisporus
Extracellular laccase (EC 1 .14.18.1) of the cultivated mushroom Agaricus bisporus was produced constitutively in defined or complex media. No enzyme induction was found after treatment with cycloheximide or with other potential inducers such as toluidine or xylidine. The enzyme was purified to homogeneity by ammonium sulphate precipitation, ion-exchange chromatography, gel filtration and affin...
متن کاملPrimordia initiation of mushroom (Agaricus bisporus) strains on axenic casing materials.
The mushroom (Agaricus bisporus) has a requirement for a "casing layer" that has specific physical, chemical and microbiological properties which stimulate and promote the initiation of primordia. Some of these primordia then may develop further into sporophores, involving differentiation of tissue. Wild and commercial strains of A. bisporus were cultured in axenic and nonaxenic microcosms, usi...
متن کاملStructural Characterization of a Water-Soluble Polysaccharide from the Fruiting Bodies of Agaricus bisporus
An edible fungal polysaccharide termed as ABP was obtained by extraction with hot water, and followed successive chromatographic purification using DEAE-Sepharose Fast Flow column and Sephacryl S-300 High-Resolution column. A symmetrical peak was obtained on high-performance size-exclusion chromatography with an average molecular weight of 5.17 × 104 Da, which was named ABP, and its main compon...
متن کاملA fruiting body tissue method for efficient Agrobacterium-mediated transformation of Agaricus bisporus.
We describe a modified Agrobacterium-mediated method for the efficient transformation of Agaricus bisporus. Salient features of this procedure include cocultivation of Agrobacterium and fruiting body gill tissue and use of a vector with a homologous promoter. This method offers new prospects for the genetic manipulation of this commercially important mushroom species.
متن کاملAn abundant hydrophobin (ABH1) forms hydrophobic rodlet layers in Agaricus bisporus fruiting bodies.
The SDS-insoluble protein fraction of Agaricus bisporus fruiting bodies was solubilized with trifluoroacetic acid. On SDS-PAGE this fraction was found to contain one abundant protein with an apparent M(r) of 16 kDa. The N-terminal amino acid sequence of this protein was determined and RT-PCR used to isolate a cDNA clone which upon sequencing identified the protein as a typical class I hydrophob...
