“…Considering the best yield obtained (rice straw), it was observed that the nutrient with the highest pre-and post-cultivation values was K, which is evidence of its importance in mushroom nutrition. K sources are commonly used in supplementation, both in spawning and in substrate formulation after wetting [34][35][36].…”

Organic agricultural waste is successfully used in the production of mushrooms as it promotes the reuse of resources and increases food production. For the formulation of the substrate for Pleurotus spp. production, the availability of nutrients must be rigorously analyzed to assess whether supplementation is necessary. The aim of this paper was to evaluate the agronomic behavior of Pleurotus ostreatus var. Florida when grown on different straws and to analyze nutrient dynamics at the beginning and end of cultivation. Straws of rice, wheat and brachiaria were used as substrates without any supplementation. The yields, biological efficiency, number and weights of mushrooms were evaluated in two crop cycles. Rice straw provided a higher yield, better biological efficiency and a greater number of mushrooms in both cultures. Wheat straw showed intermediate results for the same variables. None of the substrates showed a significant difference for mushroom weight. In the first crop, only Mg and the number of mushrooms exhibited a positive correlation; in the second crop, only K and the yield of the 1st flush showed a positive correlation. With this study, it was possible to demonstrate that agricultural residues with higher levels of K increase P. ostreatus yield, and that Mg management affects the number of mushrooms for harvesting. The results will be a useful guide for efficient and sustainable mineral supplementation of the substrate.

Green Biotechnology of Oyster Mushroom (Pleurotus ostreatus L.): A Sustainable Strategy for Myco-Remediation and Bio-Fermentation

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.

“…Mushrooms are edible fungal bodies that are enriched with polysaccharide, vitamins, and proteins but are low in calories and fats (Chen et al, 2012;Hřebečková et al, 2020). Spent mushroom substrate (SMS) is the residual or biomass waste after the mushrooms are harvested (Lou et al, 2017;da Silva Alves et al, 2021;Singh et al, 2021).…”

“…Previous studies have revealed that 1 kg of mushroom harvest generated approximately 5 kg of SMS (da Silva Alves et al, 2021;Hřebečková et al, 2020). The disposals of SMS generally include burying, incinerating, and direct discarding without pretreatments, which lead to valuable bio-resource waste, environmental pollution, and even pathogenic disease transmission.…”

Spent mushroom substrates can be utilized as organic fertilizer in agricultural production but may pose a health risk. Nitrification inhibitors dicyandiamide and 3,4-dimethylpyrazole phosphate have been used to enhance fertilizer nitrogen utilization efficiency. However, the changes of soil abiotic properties, microbial activities, nitrogen cycling and human-disease genes, and their comprehensive relationships after the spent mushroom substrate and nitrification inhibitor applications were still unknown. In this study, the spent mushroom substrate and nitrification inhibitor were applied into the agricultural soils at the rates of 2.5% (w/w) and 1.0% of nitrogen content in the spent mushroom substrate, respectively, and then lettuce was planted. Compared with the control, spent mushroom substrate application significantly increased the lettuce biomass, soil enzyme activities and chitinase, protease, nitric-oxide reductase, nitrogenase, and urease gene abundances. However, the antibiotic resistance and human-disease gene abundances were also significantly enhanced following the spent mushroom substrate application.Relative to spent mushroom substrate alone, the dicyandiamide application significantly decreased the soil pH and human-disease gene abundances, although extra dicyandiamide and 3,4-dimethylpyrazole phosphate enhanced 61.4% and 45.0% of dry biomass of aboveground lettuce. The human-disease gene abundances were positively correlated with soil pH but were negatively correlated with the Acidobacteria and Streptomyces ratios in soils. Spent mushroom substrate application could generate double-edged sword effects, and the health risk should be considered in the spent mushroom substrate applications. Extra dicyandiamide application could further promote crop growth while decrease the human-disease risk from the spent mushroom substrate.
