Summary
This study tested three types of Juncao grass as growing materials for oyster mushrooms as an eco-friendly alternative to using wood. Researchers measured how well the mushrooms grew, their nutritional value, and the enzymes produced during cultivation. The grass called Cenchrus fungigraminus produced the best results with the highest yield and quality, making it a promising sustainable solution for mushroom farming that helps reduce deforestation.
Background
Pleurotus ostreatus is the world’s third-largest commercially cultivated mushroom. Traditional mushroom cultivation using wood resources causes environmental issues such as deforestation. This study explores the use of Juncao grasses as sustainable alternative substrates for oyster mushroom cultivation.
Objective
To evaluate the influence of three different Juncao grass substrates on the physiological and enzymatic reactions of Pleurotus ostreatus, specifically assessing enzyme activities, growth, yield, and nutritional composition.
Results
Cenchrus fungigraminus produced the highest yield (159.2 g/bag) and biological efficiency (75.2%), followed by Saccharum arundinaceum (132 g/bag, 63.4%), and Miscanthus floridulus (65.1 g/bag, 28.7%). Lignin peroxidase showed the highest enzyme activity across all substrates. Heavy metals were detected within safe limits, and nutritional profiles differed significantly among substrates.
Conclusion
Cenchrus fungigraminus and Saccharum arundinaceum are suitable substrates for oyster mushroom cultivation, while Miscanthus floridulus is not recommended. Juncao grasses offer a sustainable alternative to wood-based substrates, reducing environmental impact while maintaining acceptable yields and nutritional quality.
