Shiitake (lentinula edodes) production on a sterilized bagasse substrate enriched with rice bran and sugarcane molasses

Abstract

This investigation was performed to evaluate the biological efficiency (BE), mean mushroom weight (MMW), mean number of mushroom (MNM) and mushroom quality of Shiitake [Lentinula edodes (Berk.) Pegler] when grown on a sterilized substrate composed by sugarcane bagasse enriched with rice bran and sugarcane molasses. The proportions of rice bran were 0, 15, 20, 25 and 30% (dry weight/dry weight of bagasse); and the concentrations of sugarcane molasses were 0, 30 and 60 g/kg (dry weight/dry weight of bagasse plus rice bran). Four flushes were obtained during the production cycle, providing 3 accumulated productions which were used for production analysis. The substrate supplemented with 25 and 30% rice bran yielded the highest BE (98.42 and 99.84%, respectively, about 230 days after spawning) and MNM and initially produced a lower MMW than the substrates supplemented with 15 and 20% rice bran. Any amount of rice bran added to the sugarcane bagasse improved mushroom quality, with the best production of marketable mushrooms obtained by the addition of 15% rice bran. The largest amount of sugarcane molasses (60 g/kg) increased BE (90.3 and 23.6%, on first and second accumulated productions, respectively) and MNM and no quantity affected mushroom quality.

Effect of Supplements on Growth and Nutritional Content of Pleurotus pulmonarius Cultivated on Rice Straw

“…Soya bean waste had greatest influence on stipe length and pileus diameter, while the substrate without supplement gave the lowest. Finding of this study is in line with the report of Rossi et al (2003) who reported that any amount of rice bran added to the substrate increased the number of fruiting body especially at 25% and 30% level. The increased productivity of P. pulmonarius supplemented with Brewers waste, soyabean and maize waste can be attributed to the carbohydrates, amino acids and mineral elements present in the supplements.…”

Tea waste as a supplement for the cultivation of Ganoderma lucidum

“…The effects of physical and chemical properties of substrates on mycelial growth yield and BE have been studied in Agrocybe aegerita, Volvariella volvacea, Pleurotus spp. and Lentinula edodes (Philippoussis et al 2001(Philippoussis et al , 2002Rossi et al 2003;Obodai et al 2003;Ozcelik and Peksen 2007). Yield was positively correlated with N (r = 0.683*), K (r = 0.770**), Fe (r = 0.660*), and Mn (r = 0.777**) contents.…”

Biomass, laccase and endoglucanase production by Lentinula edodes during solid state fermentation of reed grass, bean stalks and wheat straw residues

“…Wheat straw and other agricultural by-products resulting after processing of maize, cotton, sugarcane, sunflower, grape, coffee etc. have been examined as alternative substrates for its cultivation (Philippoussis et al 2002(Philippoussis et al , 2003Rossi et al 2003;Fan and Soccol 2005;Mata and Savoie 2005;Gaitán-Hernández et al 2006;Ö zçelik andPekşen 2007, Royse andSánchez 2007;Philippoussis 2009). Substrate formulation, strain genotype and length of the incubation period have been identified as important variables in L. edodes efficient production on residue-based substrates used in bag-logs (Royse and Bahler 1986;Kalberer 1995;Philippoussis et al 2001).…”
