摘要

平菇是一种被广泛栽培和研究的蘑菇，具有经济、生态和药用价值。ostreatus可以在不同的木质纤维素基质(橡木锯末、麦秸、玉米芯等)上种植。最佳生长不仅受基质组成的影响，而且受基质中水量的影响。本研究采用不同含水量(60%、65%、70%、75%)的麦秸球团培养ostreatus。菌丝生长、生物效率(BE)、底物水分、pH、酶活性及其相互关系为评价参数。结果表明，菌丝生长的最佳初始基质含水量和BE值为65% ~ 75%。另一方面，当底物含水量为75%时，水解酶和木质素降解酶(mn依赖性过氧化物酶、1,4-β-葡萄糖苷酶和纤维素生物水解酶)的酶活性最高。

Effect of different water contents in the substrate on cultivation of Pleurotus ostreatus Jacq. P. Kumm

ABSTRACT Pleurotus ostreatus is a widely cultivated and investigated mushroom for its economical and ecological values and medicinal properties. P. ostreatus can be cultivated on different lignocellulosic substrates (oak sawdust, wheat straw, corn cobs and many more). Optimal growth is influenced not only by the composition of the substrate but also by the amount of water in it. In our study, P. ostreatus was cultivated on wheat straw pellets with different water contents (60%, 65%, 70% and 75%). Mycelium growth, biological efficiency (BE), moisture of substrate, pH, enzymatic activities and relationships were the parameters that were evaluated. Based on the results, the optimum initial substrate water content for mycelial growth and BE of the substrate ranged between 65% and 75%. On the other hand, the highest enzymatic activities of hydrolytic and ligninolytic enzymes (Mn-dependent peroxidase, 1,4-β-glucosidase and cellobiohydrolase) were determined for substrates with 75% of water content.

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
