摘要

这项研究的目的是通过蘑菇栽培技术将青核桃壳(GWH)生物转化为营养食品。该研究调查了在四种不同的生长培养基中添加不同比例的青核桃壳(GWH)培养的两个分离菌株和三个分离菌株的培养周期、产量、生物效率(BE)、子实体特性和营养成分。 在该研究中,杨木锯屑(PS)被用作基本基质,青核桃壳以 9:1、8:2 和 7:3 的比例被添加到培养基中。对照培养基仅使用 PS。虽然增加 GWH 含量会延长针刺和冲洗时间,但以 10-20% 的比例添加 GWH 对蘑菇的生长性能有积极影响。根据所使用的生长培养基的不同,姬松茸和红姬菇分离菌株的产量和出菇率(%)分别介于 120.2 至 230.0 克/千克和 40.1% 至 74.2% 出菇率之间,以及 121.8 至 222.5 克/千克和 40.6% 至 76.2% 出菇率之间。此外,当在含有 GWH 的基质上生产时,尤其是在生长培养基中的比例为 20% 时,两种菌株的子实体的蛋白质和脂肪含量都有显著增加。这些结果表明,GWH(一种对环境健康构成风险的农业废弃物)可成功用于两种杏鲍菇的栽培。

Recycling biotoxic green walnut husks through mushroom cultivation and impact of these wastes on yield and nutritional composition of Pleurotus spp.

The aim of the study was the bioconversion of green walnut husk (GWH) to nutrimental foods through mushroom cultivation technology. Two isolates of Pleurotus ostreatus and three isolates of Pleurotus eryngii cultivated in four different growing media supplemented different ratios of GWH were investigated for cultivation cycle, yield, biological efficiency (BE), fruiting body properties and nutritional composition of Pleurotus spp. In the study, poplar sawdust (PS) was used as a base substrate, and GWH were added at the ratios of 9:1, 8:2 and 7:3 to prepare the growing media. The control medium was prepared using PS only. Although increasing the GWH content led to prolonged pinning and flushing times, the addition of GWH at 10–20% ratios had a positive impact on mushroom performance. The yield and BE (%) of P. ostreatus and P. eryngii isolates ranged between 120.2 and 230.0 g/kg and 40.1–74.2% BE and 121.8–222.5 g/kg and 40.6–76.2% BE, respectively, depending on the growing medium used. Moreover, the fruitbodies of both strains of P. ostreatus demonstrated significant increases in protein and fat content when produced on substrates containing GWH, especially at a 20% ratio in the growing medium. These results indicate that GWH, an agricultural waste that poses a risk to the environmental health, could be successfully used in the cultivation of both oyster mushroom species.
