“…B.E.% was similar to that reported in most studies (Familoni et al, 2018;Masevhe et al, 2016;Tekeste et al, 2020;Tisdale et al, 2006;Zervakis et al, 2013). Consistent with the literature, substrates composed of pure wood were less efficient than those composed of mixed hay-wood.…”

“…Subsequently, it spread throughout the rest of Europe both for commercialization and self-consumption. Originally performed on trunks and straw, P. ostreatus cultivation has been increasingly focused on agricultural wastes and residues within a circular economy vision (Grimm & Wösten, 2018;Masevhe et al, 2016;Ozcariz-Fermoselle et al, 2019).…”

Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom, Pleurotus ostreatus . Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection. A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such as thickness and diameter of the pileus, stipe length were assessed, as well as production variables (sprouting, fresh weight, and biological efficiency) and bromatological analysis (ash, ethereal extract, crude fiber, and crude protein). Apart from the 100%-hay substrate, biological efficiency ranged between 27% (100% apple tree as the substrate) and 140% (50% hay + 50% peach tree as the substrate). According to morphological analysis, the highest diameters were recorded from mixed substrates (50% hay + 50% wood), and a highly significant positive correlation was found between diameter and stipe length. Morphological parameters were not significantly correlated with biological efficiency. Analysis of biological efficiency confirmed that mixed substrates clustered together with 100%-wood substrates. Bromatological analysis showed that the mixed substrate (50% hay + 50% pear tree) had the highest protein content among the novel tested substrates. Bromatological parameters were not significantly correlated with biological efficiency. In conclusion, pruning residues from fruit trees can be valuable by using them as substrates for the cultivation of P. ostreatus . Production is quantitatively competitive with that using hay, on the condition that wood is mixed with hay.

“…The rational choice of the substrate is one of the most important aspects in mushroom cultivation [59]. 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].…”

“…In many studies, remarkable variations have been observed in the nutritional contents of P. ostreatus grown on different substrates [72][73][74][75]. 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 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.

“…On an industrial scale, P. ostreatus is grown on cereal straw, mainly wheat straw (Rühl and Kües 2007 ). However, in many regions of the world, wheat straw is becoming less available and expensive (Masevhe et al 2015 ; Picornell-Buendía et al 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.
