Xylanolytic enzymes produced by Lentinula edodes UFV70, cultivated in eucalyptus sawdust/rice bran medium, were stable at 50, 60 and 65°C for 21 hours, losing only 15-25% activity. Fungus incubation at 50°C for 12 hours and at 65°C for 24 hours increased the amount of xylose produced.

Production and consumption of edible mushrooms have grown continuously in the last fifteen years, particularly due to interest in their nutritional and health benefits. The three most cultivated mushrooms worldwide are Agaricus bisporus (common mushrooms), Lentinus edodes (shiitake) and Pleurotus spp. (oyster mushroom). Mushrooms are highly perishable. They tend to lose quality right after harv...

Aqueous extracts of seven species of edible mushrooms were tested for their antitumor activity against transplanted Sarcoma 180 in Swiss albino mice. All of the aqueous extracts except that of Auricularia auricula-judae (Bull. cx Fr.) QUé1. highly inhibited the growth of transplanted tumors. The active antitumor component of Lentinus edodes (Berk.) Sing. was not adsorbed by the acetate form of...

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screeni...

Macrophages were activated with a lignin derivative (EP3) purified from the water extract of the culture mediumof Lentinus edodes mycelia (LEM). When human urinary bladder carcinoma cells (HUB-15) were co-cultured with lignin-activated macrophages, HUB-15 cell almost completely came off from the culture surface. Recently, it was reported that LEM activated macrophages in vitro}] This led us to ...

The present study was an attempt on commercialization of shiitake mushroom (Lentinus edodes). For spawn production, the additive CaCo significantly enhanced the mycelial growth and basidiocarp 3 formation. The substrate Ill-filled paddy with additive CaCO enhanced the browning of mycelia (16.40 days), 3 basidiocarp formation (51.80 days), yield (360.70 g/kg) and biological efficiency (36.07 per...
