Yield, quality and enzyme activity of shiitake mushroom (Lentinula edodes) grown on different agricultural wastes

Abstract

In this study, it was aimed to investigate cultivation of Lentinula edodes by using different agricultural wastes (oak sawdust, poplar sawdust, wheat stalk, peanut shell, corncob and vine pruning waste) and to determine the most suitable growing mixture/mixtures. For this purpose, 12 growing mixtures were tested. Within the scope of the experiment, besides measurement of yield and quality parameters of mushrooms, properties of agricultural wastes and enzyme activities (laccase and cellulase) of mixtures at different periods were measured. Based on results of the study, the highest and lowest amounts of nitrogen were obtained from after harvest (1.71%) and after sterilization (1.34%) periods, respectively. While the highest amount of carbon was at the after-sterilization period (46.6%), the lowest amount was recorded at the after harvest (45.64%) period. The fastest and slowest mycelia development time was observed in A7 (21.67 days) and A4 (50 days) mixtures, respectively. While the highest yield was determined in A5 (299.59 g kg-1) mixture, A9 (55.99 g kg-1), A6 (65.59 g kg-1) and A11 (75.47 g kg-1) gave the lowest results. While the highest biological activity rate was recorded in A3 (93.65 %) and A5 (92.90%), the lowest was observed in A11 (21.45%), A6 (19.85%) and A9 (19.22%) mixtures. The highest and lowest protein amounts were determined in the A5, A7 and A10, A9 and C mixtures, respectively. The highest cellulase and laccase activities were found in A3 (3.16 IU g-1) and A7 (2164.48 U g-1), respectively.
