“…Moreover, the biological efficiency obtained in wheat straw in the current study was higher than that reported in the earlier works [ 46 , 55 , 56 ]. Also, supplementation with maize waste water [ 19 ] and olive mill waste [ 48 ] resulted in lower biological efficiency of P. ostreatus in comparison with that obtained in the commercial control of the current study.…”

“…Oyster mushroom could help managing the disposal of agrowastes [42], especially lignocellulosic ones [43], reducing environmental and soil pollutions [44,45]. Production of the wheat straw substrate was earlier compared with that of the work of Naim et al [46]. e substrate WS : OLPR 1 : 3 has hastened the fruit formation by 3.7 d in comparison with control, compared with a hastening by 3.4 d with WS : OLPR 3 :1 substrate as reported by Koutrotsios et al [47].…”

In several Mediterranean countries, olive pruning residues (OLPRs) are abandoned or burned leading to several environmental problems. Valorization of these agrowastes could be a challenge for the primary decomposer Pleurotus ostreatus, turning them into edible biomass. The OLPR was used alone (OLPR), or in mixtures with wheat straw (WS : OLPR 1 : 3 v/v and WS : OLPR 3 : 1 v/v). Mycelial colonization was hastened by 3.7 days in WS : OLPR 1 : 3 (v/v). Yields were comparable to control (WS) in WS : OLPR 3 : 1 (v/v). Organic matter loss decreased with increasing proportions of OLPR in substrates. The nutritional value of mushrooms was improved by lower fat and sodium contents, in WS : OLPR 1 : 3 (v/v) and WS : OLPR 3 : 1 (v/v), and higher total protein, crude fiber, iron, and total carbohydrates contents in WS : OLPR 3 : 1 (v/v), compared with those of control. Polyunsaturated fatty acids, mainly linoleic acid, were the most abundant in mushrooms. Monounsaturated fatty acids increased in mushrooms of the substrates containing OLPR. A good predictive model of partial least square regression analysis showed different relationships of mushroom palmitic, oleic, linolenic, palmitoleic, and stearic acids with substrate composition. Findings suggested the use of OLPR as a supplement to commercial wheat straw and as a tool to reduce the negative impacts of their hazardous disposal on the environment.

“…The expensive importation and acquisition of commercial substrate had previously led to the use of locally available agro-industrial wastes (Abou Fayssal et al, 2020;Naim et al, 2020aNaim et al, , 2020bSassine et al, 2007;El Sebaaly et al, 2018a, 2018c, 2018b in mushroom production. At industrial scale, P. ostreatus is cultivated on cereal straw, mainly wheat straw (Labuschagne et al, 2000), which is becoming less available in many world regions causing constraints for oyster production (Picornell-Buendía et al, 2016).…”

“…Furthermore, nanometric size supplements, specially developed for mushroom cultivation, have not been reported yet. Otherwise, the use of nano-fertilizers, initially developed for use on plant crops as supplements for the growing substrate of P. ostreatus , had recently come out with meaningful results, mainly when the product was applied twice during the production cycle (Naim et al 2020 ). Consequently, the current study investigated the effect of a nano-fertilizer containing an admixture of 25% l -amino acids, in different doses and application timings on P. ostreatus growth, production, and amino acid composition.…”

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.
