The antibacterial activity of 35 isolates of Lentinula edodes, a shiitake mushroom, against Bacillus subtilis was evaluated by diffusion technique in agar with a semi-solid overlay. All isolates inhibited B. subtilis and the isolate Le1 promoted the formation of the largest inhibition zone. L. edodes Le1 also presented antibacterial activity against foodborne pathogens and food contaminant bact...

Organosulfur compounds are the basis for the unique aroma of Lentinula edodes, and cysteine sulfoxide lyase (C-S lyase) is the key enzyme in this trait. The enzyme from Alliium sativum has been crystallized and well-characterized; however, there have been no reports of the characterization of fungi C-S lyase at the molecular level. We identified a L. edodes C-S lyase (Lecsl), cloned a gene of C...

Substrate formulations of sawdust, wheat bran, and millet were inoculated with spawns from one hybrid and two parental genotypes of Lentinula edodes. Biological efficiency (BE) and size data on mushrooms harvested from two substrate formulations with spawn run times of 60, 90, and 120 days were analyzed. A significant genotype-spawn run time-substrate formulation interaction was observed for BE...

Three experiments were performed to determine the effect of selected saccharides on mushroom yield and basidiome size of shiitake (Lentinula edodes) when grown on a synthetic substrate. Substrate formulations of sawdust, wheat bran, and millet were nonamended or amended with sucrose, fructose, or glucose. Addition of sucrose (0.6 to 1.2% [dry weight]) to the substrate stimulated mushroom yield ...

Shiitake mushrooms (Lentinula edodes) containing β-glucans may be beneficial for human health; they have been used in the treatment of cancer, hypertension, and high cholesterol levels. The objective of this study was to determine the β-glucan content in different sections of the fruiting bodies and mycelia of ten shiitake mushroom cultivars. The measured β-glucan content ranged from 20.06 ± 1....

A multicomponent protein complex containing manganese (II)-dependent peroxidase, laccase and beta-glucosidase was isolated from culture extracts of the white rot basidiomycete Lentinula edodes. This protein complex showed a single protein band on native polyacrylamide gel electrophoresis (PAGE). On sodium dodecyl sulfate (SDS)-PAGE, however, it displayed three major bands and several additional...

Traditionally, Lentinula edodes are used in many Asian countries for the treatment of various chronic diseases. In current study, ethyl acetate fraction fruit body was obtained by standard bioassay-guided fractionation procedure. This resulted isolation three bioactive compounds (compound 1 already reported, compound 2 and 3 first time reported from this mushroom) their structures were characte...

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...
