摘要

本研究旨在探讨蘑菇提取物固体培养基对杏鲍菇菌丝体的β-葡聚糖含量、生长速度、密度和生物量的影响。将新鲜、优质的杏鲍菇原料洗净、切片,然后放入密封的高压锅中以 90°C 的温度在干燥柜中加热 4 小时。加热过程结束后,进行离心分离。将不同浓度的麦芽提取物与蒸馏水(0%、25%、50%、75% 和 100%)混合,制成无菌固体培养基。以麦芽提取物为基础的培养基作为对照。本研究的重点是奥氏蘑菇菌丝在其自身的蘑菇提取物培养基上的生长表现,这对经济和环境都具有重要意义。在为期六天的观察期间,菌丝在所有测试培养基上都表现出一致的生长,保持了 15 毫米的稳定生长速度。蘑菇提取物含量的增加源于菌丝密度和生物量含量的提高。由此可以推断,当使用的培养基中蘑菇提取物稀释比例低于 25% 时,β-葡聚糖的形成量较少。需要进一步研究从不同类型的蘑菇副产品中提取的蘑菇提取物,因为这些副产品达不到商业标准。

Enhancing Biomass and β-Glucan Yield from Oyster Mushroom Pleurotus ostreatus (Agaricomycetes) Mycelia Through Extract Valorization
This study aimed to examine the impact of mushroom extract-based solid media on the β-glucan content, growth rate, density, and biomass content of Pleurotus ostreatus (oyster mushroom) mycelia. Fresh, high-quality raw P. ostreatus were washed, sliced, and heated in a sealed pressure cooker at 90°C for 4 hours in the drying cabinet. Following the heating process, centrifugation was carried out. Different concentrations of Pleurotus ostreatus extract were mixed with distilled water (0%, 25%, 50%, 75%, and 100%) and prepared for a sterile solid media. A malt extract-based medium was maintained as a control. This study focuses on the growth performance of P. ostreatus mycelium on its own mushroom extract-based culture medium which holds considerable economic and environmental significance. During the six-day observation period, the mycelium exhibited consistent growth across all tested media, maintaining a steady growth rate of 15 mm. The increased content of mushroom extract resulted from the enhanced density of the mycelia and biomass content. It can be inferred that when media containing less than 25% of mushroom extract dilution is used, β-glucan can be formed in smaller amounts. Further research is needed to explore mushroom extract derived from different types of mushroom byproducts, which fail to meet commercial standards.

期刊介绍: The rapid growth of interest in medicinal mushrooms research is matched by the large number of disparate groups that currently publish in a wide range of publications. The International Journal of Medicinal Mushrooms is the one source of information that will draw together all aspects of this exciting and expanding field - a source that will keep you up to date with the latest issues and practice. The International Journal of Medicinal Mushrooms published original research articles and critical reviews on a broad range of subjects pertaining to medicinal mushrooms, including systematics, nomenclature, taxonomy, morphology, medicinal value, biotechnology, and much more.
