Shiitake Dermatitis is often presented as papules and erythemato-violaceous linear streaks. It can be associated with bleomycin treatment, dermatomyositis and shiitake mushroom (Lentinus edodes). There is not any previous report concerning this rare etiology in our country. Shiitake is the second most consumed mushroom worldwide and it can cause flagellate erythema when ingested raw or half coo...

Aim of study: The possibilities using oak and beech wood wastes used in the cultivation Lentinus edodes fungus production pcl biocomposite film material were investigated. Material methods: mushroom was subjected to 2 harvest periods both lignocellulosic waste types equal degradation times obtained. Chemical contents degraded fibers determined. Then, effect produced 15% 30% raw on mechanical pr...

Some Basidiomycota were chosen for studies of key ligninases synthesis (25°C, 30 days) in modified medium (shaken or not cultures) with added wheat straw. Liquid Czapek medium with straw yielded a higher amount of laccase than peroxidase, ground straw induced enzyme worse than chopped straw. With peroxidase the reverse dependencies were observed. Laccase of Lentinus edodes synthesized two enzym...

Shiitake (Lentinus edodes) is the second most consumed mushroom in the world. It has long been known in Asian medicine for its anticarcinogenic, antihypertensive and serum cholesterol level reduction properties. Nevertheless, the consumption of raw or not well-cooked mushrooms may cause skin eruptions which usually occur 24 to 48 hours after ingestion and are characterized by linearly arranged ...

We have previously isolated a developmentally regulated novel gene, priA, from the basidiomycete Lentinus edodes. The deduced PRIA protein contains the two set of motifs similar to a 'zinc finger' typified by transcription factor TFIIIA and the motif of a 'zinc cluster' observed in metallothioneins. It also contains a hydrophobic N-terminal sequence. Here Escherichia coli cells producing PRIA w...

Six polysaccharide preparations, lentinan, LC-11, LC-12, LC-13, EC-11, and EC-14, were isolated from the watersoluble extracts of Lentinus edodes (Berk.) Sing., an edible mushroom, by fractional precipitation with ethanol and cetyltrimethylammonium hydroxide, fractional solubilization with acetic acid, and diethylaminoethyl cellulose column chromatography. The first two polysaccharide preparati...
