摘要

An evaluation was made of the production of four strains of Lentinida edodes. All strains (IE-40, IE105, IE-124 and IE-256) were kept in pure cultures at 25°C. Different types of spawns were prepared:Control (C) (millet seed,100%),F1 (millet seed,88.5% ;wheat bran,8. 8% ;peat moss, 1.3% ;and CaS04,1.3%) and F2 (the same formula as Fl, but substituting the wheat bran with powdered wheat straw). Wheat straw was pasteurized by soaking it for 1 h in water heated to 65℃. After to this the substrate (2 kg wet weight) was placed in polypropylene bags with micropore filters. The bags were inoculated with each spawn (5% w/w) and incubated in a dark room at 25℃. To determine the chemical composition of mature fruiting bodies that were obtained from the first crop,a proximal analysis was conducted:total mineral content,crude fat content,crude protein content (N×4. 38) and moisture content. Available carbohydrates and total calories (energy value) were also calculated. The mean Biological Efficiency (BE) varied between 66. 01% (C-IE-256) and 320.15% (F1-IE-124) ,with an average per strain of 125. 64%, and with statistical difference among IE-124 from the rest of the strains. The highest mean BE was observed on spawn Fl (188. 35%), significantly different from C and F2. The protein content of fruiting bodies was high, particularly in strain IE-40-Fl (17. 79%). Minerals, protein, and crude fat contents were similar to those cited by other authors. The amount of fat varied from 1. 14 (Fl-IE-40) to 2. 16% (F2-IE-105) on dry matter. Carbohydrates ranged from 58. 81% (Fl-IE-40) to 66.17% (F1-IE 256). The energy value determined ranged from 302. 95 kcal (F1-IE -40) to 332.02 kcal (F1-IE-256). The variability on BE observed in this study was significantly influenced by the spawn's formulation and genetic factors of the different strains.
