“…Studies on the role of spent mushroom substrates after this cultivation produces many important materials, such as enzymes [12,19,126,127], biomass [118,128,129], bioethanol [19,127,130], feed ingredients, and functional foods [61,131,132]. Spent mushroom substrates can be recycled as a substrate for the "new cultivation cycle" of mushrooms, a feedstock for producing the second generation of biofuels, a bio-control agent, a biofertilizer, and for soil amendment [133][134][135]; 2.…”

The field of biotechnology presents us with a great chance to use many organisms, such as mushrooms, to find suitable solutions for issues that include the accumulation of agro-wastes in the environment. The green biotechnology of mushrooms (Pleurotus ostreatus L.) includes the myco-remediation of polluted soil and water as well as bio-fermentation. The circular economy approach could be effectively achieved by using oyster mushrooms (Pleurotus ostreatus L.), of which the substrate of their cultivation is considered as a vital source for producing biofertilizers, animal feeds, bioenergy, and bio-remediators. Spent mushroom substrate is also considered a crucial source for many applications, including the production of enzymes (e.g., manganese peroxidase, laccase, and lignin peroxidase) and bioethanol. The sustainable management of agro-industrial wastes (e.g., plant-based foods, animal-based foods, and non-food industries) could reduce, reuse and recycle using oyster mushrooms. This review aims to focus on the biotechnological applications of the oyster mushroom (P. ostreatus L.) concerning the field of the myco-remediation of pollutants and the bio-fermentation of agro-industrial wastes as a sustainable approach to environmental protection. This study can open new windows onto the green synthesis of metal-nanoparticles, such as nano-silver, nano-TiO2 and nano-ZnO. More investigations are needed concerning the new biotechnological approaches.

“…Different types of SMS may yield different nutrient compositions due to different matrix composition and pretreatment methods. 97 However, in the case of biogas produced from mushroom by-products, mechanical pretreatments (such as grinding or ultrasonic treatment) consume more energy than the energy (methane) they produce, which may result in the cost for pretreatments ultimately being higher than the effective return. 98 Sawdust used for mushroom cultivation was at a very high cost of $19.31.…”

Valorization of mushroom by‐products: a review

2022

View full text Add to dashboard Cite

With the rapid growth of the global economy and the global population, the production of solid waste has increased remarkably. Mushrooms are gaining popularity among researchers for their ability to turn waste into nutrients. However, a large number of by‐products are produced during the industrial processing of mushrooms. Traditional waste management, focusing on the utilization and disposal of mushroom by‐products, has attracted the attention of researchers. Meanwhile, the circular economy has become a multidisciplinary research field, and the valorization of mushroom by‐products is a very important part of circular economy research. Various mushroom by‐products of mushroom are reviewed in this paper. By‐products are used in food as raw materials or functional components, in livestock and poultry feed after grinding/fermentation, and as electrochemical materials and papermaking materials. The by‐products can also be used to produce ethanol and other biological sources of energy, as absorbing substances in sewage treatment, and as fertilizer in soil amendment. Mushroom processing by‐products can be applied in various fields. To improve production efficiency, new extraction technology (including supercritical fluid technology and microwave extraction technology) can be adopted to increase the bioactive substance content in the by‐products. Choosing appropriate processing temperature, time, and other processing conditions can also enhance product quality. Finally, more research is needed on the cost‐effective utilization of the by‐products and the feasibility of industrialization. © 2022 Society of Chemical Industry.

“…The application of this waste as a soil amendment after an appropriate composting process is considered to be a viable process. It could be of interest to enhance the sustainability of agricultural production systems as it is indicated in different reviews on the use and valorisation of SMS (Kit-Leong et al, 2022;Mohd Hanafi et al, 2018;Umor et al, 2021) given their ability to enrich the soil in OM and nutrients (Joniec et al, 2022) similar to other organic residues such as vegetable, fruit or garden waste compost (Arthur et al, 2011).…”
