平菇是平菇属的一种，被公认为产生具有重要药用特性的次级代谢产物。研究了香蕉废弃物栽培平菇提取物的抗氧化性和抑菌性。乙醇提取物对革兰氏阳性菌和革兰氏阴性菌表现出抗菌活性，其对所有测试真菌的体外抗真菌活性显示了很好的作用。定性植物化学分析的Plephilis上生长的酵母葡萄糖肉汤和香蕉农作物废料证实类固醇，强心苷，萜类化合物和生物碱的存在下，而乙醇提取物40天后表现出的苯酚浓度为521.67 μ g/mL的香蕉废物相比，155 μ g/mL的酵母葡萄糖肉汤。乙醇提取物的最小抑菌浓度范围为19.74至56.84 mg/mL和35.53至102.31 mg/mL，分别在固态和淹没生长的菌丝体提取物，40天后。此外，香蕉农业废弃物可能是平菇生产的重要经济来源。糙皮侧耳的营养、药用和抗菌特性可用于开发新的营养制剂;它也可用作常规和快餐食品的添加剂。
Oyster mushrooms, species of the genus Pleurotus, are recognized for producing secondary metabolites with important medicinal properties. Investigations were carried out to evaluate the antioxidative and antimicrobial properties of the edible mushroom Pleurotus ostreatus (MTCC142) extracts cultivated on banana agrowastes. Ethanolic extracts showed antimicrobial activities against gram-positive and gram-negative bacteria, and their in vitro antifungal activities against all fungi tested revealed a promising role. Qualitative phytochemical analysis of Pleurotus grown on yeast dextrose broth and banana agrowaste confirmed the presence of steroids, cardiac glycosides, terpenoids, and alkaloids, whereas ethanolic extract after 40 days exhibited a phenol concentration of 521.67 mu g/mL in banana waste compared to 155 mu g/mL in yeast dextrose broth. The minimum inhibitory concentration of ethanolic extracts ranged from 19.74 to 56.84 mg/mL and 35.53 to 102.31 mg/mL, in solid-state and submerged grown mycelium extracts, respectively, after 40 days. Moreover, banana agrowaste could be a significant economic source for the production of the oyster mushroom P ostreatus. The nutritive, medicinal, and antimicrobial properties of P. ostreatus can be used to develop a new nutraceutical formulation; it can also be used as an additive to routine and fast food.
