Two new sterols, (22E)-23-methylergosta-5,7,22-trien-beta-ol (1) and 5alpha,6alpha-epoxy-(22E)-ergosta-8,14,22-triene -3beta,7alpha-diol (2), have been isolated from two edible mushrooms, Lentinula edodes and Tricholoma matsutake, respectively, together with twelve known ones (3-14). The structures of the new compounds were elucidated on the basis of their spectral data.

This study aimed to enhance the degrading ability of microcrystalline cellulose in the mycelia of the mushroom Lentinula edodes. The mycelia were incubated in an autopolyploidization medium containing colchicine for more than 1 week at low temperature. After incubation, many larger nuclei (autopolyploid nuclei) were observed in the mycelia.Mycelial mats were then incubated on agar medium contai...

Lignocellulosic residues were tested as artificial log to mushroom production of Lentinula edodes. Three isolates of L. edodes were grown in substrates based on corn bog, and sawdust or bark of eucalypt, enriched with rice bran 20%. The biological efficiency (BE) were higher when corn borg and sawdust was used and the isolate UFV 73 was that presented well shaped mushrooms and higher productivi...

Antibacterial activity of Lentinula edodes against Bacillus subtilis was evaluated in cell-free filtrates obtained after growth in 14 different culture media. The highest B. subtilis growth inhibition was promoted by filtrates of growth media supplemented with rice bran, vermiculite or molasses. L. edodes dry mycelial biomass in liquid culture with 0.5% added rice bran was 3.2 mg/ml, after grow...

To investigate the effects of lentinan from Lentinas edodes and polysaccharides from Agaricus blazei (ABPS) on the expression of cytochrome P450s (CYPs), lentinan (10 mg/kg/day) or ABPS (200 mg/kg/day) was administered to female BALB/c mice four times every other day by intraperitoneal injection. Lentinan and ABPS suppressed both the constitutive and 3-methylcholanthrene-induced CYP1A expressio...

The objectives of this study were to evaluate applicability of food waste compost (FWC) as a substrate for cultivation of Ganoderma lucidum, Lentinula edodes, and Pholiota adipose, and to determine contents of Ca, Mg, Na, and K in fruiting bodies (FB). FB yield per substrate in FWC-free controls was 53 ± 4 g/kg for G. lucidum, 270 ± 90 g/kg for L. edodes, and 1,430 ± 355 g/kg for P. adipose. Su...
