“…The BE values for strains S610 (50.2 %), M115 (53.27 %), and IE-40 (55.6 %) coincide with data cited by Mata et al [22] (24±59%). They cultivated the same strains on wheat straw with peat moss pasteurized at 65 C for 24 h. Savoie et al [32] also described the utilization of pasteurized wheat straw, which was subjected to several treatments; employed for four of the strains evaluated in this study (A9, S610, M115, IE-40).…”

Five edible Lentinula edodes strains were evaluated. The mushrooms were cultivated on a wheat straw substrate that was previously pasteurized by immersion in water heated by residual geothermal vapor, which was also used to warm incubation and production rooms. Finely chopped wheat straw (Triticum aestivum L.) was pasteurized and then spawned with supplemented spawn capable of supplying nutrients and enriching the substrate, with the expectation of yield improvement. The samples were incubated for 60 days before the production started and thus, the mushrooms produced had pileus diameters ranging from 5 to 20 cm. The yields fluctuated from 6.2 to 13.9 % (fresh weight of mushrooms/fresh weight of substrate). Biological efficiency ranged from 24.8 to 55.6 % (fresh weight of mushrooms/dry weight of substrate), while the production rate reached varied from 0.19 to 0.55 % (biological efficiency/production time starting from inoculation). The cultivation system evaluated here offers the possibility of lowering production costs by cultivating the mushroom on easily obtainable substrate and shortening the culture cycle. The efficiency of this use of geothermal energy and supplemented spawn for shiitake mushroom cultivation on non‐sterilized substrates was proven.

“…The number of shiitake strains that are well adapted to grow on pasteurized wheat straw is relatively low (Levanon et al , 1993; Mata and Savoie, 1998; Mata et al , 2002) and this substrate is easily contaminated with antagonistic fungi. However, it has been demonstrated that the use of supplemented spawn reduces substrate contamination considerably (Mata et al , 1998; Sovoie et al , 2000). …”

The research evaluated the interactions of two main factors (strain / types of spawn) on various parameters with the purpose to assess its effect on yield and biochemical composition of Lentinula edodes fruiting bodies cultivated on pasteurized wheat straw. The evaluation was made with four strains (IE-40, IE-105, IE-124 and IE-256). 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 F1, but substituting the wheat bran with powdered wheat straw). Wheat straw was pasteurized by soaking it for 1 h in water heated to 65 °C. After this the substrate (2 kg wet weight) was placed in polypropylene bags. The bags were inoculated with each spawn (5% w/w) and incubated in a dark room at 25 °C. A proximate analysis of mature fruiting bodies was conducted. The mean Biological Efficiency (BE) varied between 66.0% (C-IE-256) and 320.1% (F1-IE-124), with an average per strain of 125.6%. The highest mean BE was observed on spawn F1 (188.3%), significantly different from C and F2. The protein content of fruiting bodies was high, particularly in strain IE-40-F1 (17.7%). The amount of fat varied from 1.1 (F1-IE-40) to 2.1% (F2-IE-105) on dry matter. Carbohydrates ranged from 58.8% (F1-IE-40) to 66.1% (F1-IE-256). The energy value determined ranged from 302.9 kcal (F1-IE-40) to 332.0 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.

“…He also found that endoglucanase and β-glucosidase activity increased slightly at the time of fruiting. Mata et al (30) have mentioned that endoglucanase production is associated with other primordium and fruiting formation stages where there has been a significant increase in enzymatic activity. As we found in this study, Leatham and Leonard (22) mentioned that, during mycelial growth, L. edodes uses the most accessible sources of carbon, such as free sugars, starch, pectins and hemicelluloses.…”

The chemical changes in barley-straw (BS), wheat-straw (WS) and vineyard-pruning (VP) substrates were determined during colonization of Lentinula edodes mycelia (during primordium development) in solid state fermentation. Primordia appeared 39-50 days after inoculation. VP appeared to promote early sporophore initiation. The concentration of hemicellulose in BS and VP decreased gradually from 25.5% to 15.6% and from 15.8% to 12.3%, respectively. However in WS, hemicellulose decreased from 27.2% to 9.5%. Lignin broke down continuously in BS and WS, with 31.8% and 34.4% degradation, respectively; higher than that of cellulose. During the pinning stage, the C:N ratio decreased in VP and BS, but not in WS. On all substrates the phenols decreased notably throughout the first week of mycelial growth. The time elapsed (days) to pinning was positively correlated with cellulose content (r=0.89), total sugar (r=0.85) and inversely correlated to lignin (r=−1.00) and phenol content (r=−0.55).
