“…In Spain, the Mushroom Research, Experimentation and Services Center (CIES) has carried out different investigations on the reuse of a wheat straw-based substrate, previously used in growing cycles of P. ostreatus, in new production cycles of the same fungus (double-cropping) [48,[76][77][78][79][80][81]. For this, the effect of the addition of different enrichment materials, such as commercial supplements, wheat straw and wheat bran, as well as combinations with SMS of A. bisporus has been studied.…”

Use of Spent Mushroom Substrate in New Mushroom Crops to Promote the Transition towards A Circular Economy

et al. 2020

The use of spent mushroom substrate (SMS) in new cultivation cycles has already been reported due to its economic and environmental viability. When considering the application of the circular economy concept in the production of edible mushrooms, the re-use of the SMS within the same process is highly attractive, because it allows a better use of the biomass and the energy involved in the process and, therefore, tends to improve energy efficiency and resource conservation. However, this alternative generates important challenges, which derive from maintaining the quality standards of the mushrooms produced and, at the same time, not incurring excessive costs that are detrimental to the process itself. In our opinion, the main difficulty of the process in achieving success is regarding the biological and agronomic parameters that involve the production of the mushroom. It is useless to apply SMS in new cycles if the mushroom harvest is impaired and farms become non-viable. However, numerous examples are reported here where SMS was recycled into new substrates for either the same or different mushroom species without negatively affecting yield compared with using substrates prepared from 100% fresh raw materials. Thus, we suggest that each farm has its own specific technological study, since a small variation in the raw material of the compost, and mushroom cultivation practices and casing layer used, can influence the entire viability of the mushroom circular economy.

“…Recently, there is a growing interest in utilising easily available low-cost alternative materials for P. ostreatus cultivation [76][77][78][79]. Spent mushroom substrate can be a good component for P. ostreatus cultivation [80][81][82][83][84][85]. However, scientific evidence supporting the utilisation of spent substrates especially from other mushroom species in P. ostreatus cultivation is still in its infancy.…”

“…Generally, wheat straw is used as the main substrate for P. ostreatus commercial cultivation [13]; however, there is a growing interest in highly available low-cost alternative materials [76][77][78][79]. According to Ashrafi et al [39], Jo et al [80], Pardo-Giménez et al [81], Wang et al [82], Picornell et al [83], Picornell-Buendía et al [84], and Economou et al [85], spent mushroom substrate can be an effective component of traditional growing media for the cultivation of oyster mushrooms.…”

The Utilisation of Pholiota nameko, Hypsizygus marmoreus, and Hericium erinaceus Spent Mushroom Substrates in Pleurotus ostreatus Cultivation

2021

The feasibility of utilising spent mushroom substrates (SMSs) as a growing medium component for Pleurotus ostreatus cultivation was investigated. P. ostreatus was cultivated on traditional wheat straw (control) and wheat straw substrate supplemented with SMSs from Pholiota nameko (N-SMS), Hypsizygus marmoreus (M-SMS), and Hericium erinaceus (E-SMS) in varying supplementation rates (10%, 20%, and 30%). The yield, biological efficiency (BE), dry matter, and protein content of P. ostreatus fruiting bodies grown on ten substrates were evaluated. Significant differences in yield, BE, protein content, and dry matter of P. ostreatus were found among the studied substrates. The highest yield was recorded in 20% E-SMS (254.33 g), 20% N-SMS (253.43 g), and 10% E-SMS (251.67 g). The biological efficiency ranged from 66.48% (30% M-SMS) to 72.67% (20% E-SMS) and followed a similar trend to yield. The highest protein content was recorded in 30% M-SMS (29.93 g∙100 g dry weight−1). The highest dry matter of P. ostreatus was noticed in 30% of M-SMS (23.74 g) and 10% of M-SMS (23.06 g). Therefore, the spent mushroom substrates of Ph. nameko, H. marmoreus, and H. erinaceus could be used as a potential, low-cost sustainable alternative (10–30%) and as a renewable component of traditional growing media for P. ostreatus cultivation.

“…Pleurotus ostreatus can decompose the cellular wall components present in the raw lignocellulosic material, like cellulose, lignin, and hemicellulose through the action of complex oxidative and hydrolytic enzymatic systems (Castro 2003;Fernández-Fueyo et al 2016). Among others, hemicellulases, cellulases, and ligninases enzymes degrade long and insoluble parts of lignocellulosic materials into soluble components of low molecular weight that are taken by intracellular enzymes of fungi for their nutrition (Kurt and Buyukalaca 2010;Picornell-Buendía et al 2015). Hemicellulose, cellulose, and lignin serve as an energy source for fungal growth because they contain carbon, hydrogen, and oxygen, clarifying their decrease along the cultivation cycle (Andrade et al 2010).…”

“…However, SMS may not produce excellent mushroom yield by itself because of the reduction in nutrients due to their subsequent utilization by mushroom mycelium (Sharma and Jandaik 1985). Recycling of such substrate through amendment with nutritional supplements, especially protein-rich ones, to help further mushroom production is a practical choice to adapt to the high volume of this waste material (Pardo-Giménez et al 2011;Pardo-Giménez et al 2012;Picornell-Buendía et al 2015, 2016a.…”

Supplementation of the spent oyster substrate enhances its nutritional properties to produce a new mushroom cropping cycle. The study investigated the potential of a nano-fertilizer (Lithovit®-Amino25) with an admixture of 25% l-amino acids on Pleurotus ostreatus production, proteins, and amino acid contents. The product applied at spawning (t1), after the first harvest (t2), and at both timings (t3), in two doses: 3 g/kg (C1) or 5 g/kg (C2). Compared with control (C0t0), the first harvest was earlier by 2.3–3.3 days in C1t1 and C2t1. The biological yield of the second harvest was improved by 28.0% in C2t2. Superior results were in C1t3 where the number of crops increased to four, biological efficiency was optimized (117.3%) at the third harvest, and biological and economic yields increased by 36.7% and 36.4%, respectively. Lignin was the most degraded in C1t3, while residual cellulose, hemicellulose, neutral detergent fiber, and acid detergent fiber were higher in all treated substrates than in control. In C2t1, mushrooms were the richest in proteins, while in C1t1, they were the richest in the essential amino acids threonine, valine, isoleucine, leucine, and histidine. Lithovit®-Amino25 has a high potential for use in P. ostreatus production.
