Influence of substrates on the nutritional quality of Pleurotus pulmonarius and Pleurotus ostreatus

Abstract

This investigation is aimed at determining the influence of agro-wastes as substrates on the nutritional quality of Pleurotus pulmonarius and Pleurotus ostreatus. Cassava peels, banana leaves and amended sawdust (sawdust mixed with rice bran in ratio 4:1) were used as growth substrates. Proximate and mineral analyses were carried out using DA 7250 NIR Analyzer and Atomic Absorption of Spectrophotometer machine (AA320N). Both species in amended sawdust had the highest stipe length and pileus diameter of the fruiting body. Starch was the most abundant proximate constituent in the two species. The starch was the most abundant proximate constituent in the two species but highest starch contents were observed in. P. pulmonarius grown in cassava peels substrate and P. ostreatus raised in banana leaves substrate. Fat appeared to be the lowest proximate constituent in the two species. Potassium was predominant among the minerals in both P. pulmonarius and P. ostreatus and the highest value (68.204 mg/L) was observed in P. ostreatus cultivated in amended sawdust. Other minerals varied considerably and as they were differential affected by the substrates. The mushrooms contained useful nutritional constituents however their quantities were influenced by the substrates used in raising them.

Assessment of lignocellulosic residues from Northern Patagonian Andes (Argentina) for cultivation of Pleurotus ostreatus

“…It has been suggested that BE should be at least 50 % for a profitable cultivation for Pleurotus species [30]. In this work, the highest BE values were obtained in substrates formulated with WS (up to 43:55 % in strain 129, and up to 72:45 % in strain A01), in accordance with previous reports in this genus [3,5,31,32]. It should be noted that although WS is an abundant and low-cost lignocellulosic residue in the Argentine Pampas region [4], it is of limited availability in Patagonia, and is commercialized principally as livestock.…”

Pleurotus ostreatus, mushrooms production using quick and cheap methods and the challenges to the use of coffee husk as substrate

“…Some authors have also observed a change in the nutritional composition according to the substrate, for both Pleurotus pulmonarius and P. ostreatus (Garuba et al, 2017).…”

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

“…As reported by Raman et al [50], the protein content in P. ostreatus may depend on many factors. The significant influence of the kind of cultivation substrate on the protein content in P. ostreatus fruiting bodies was noticed by many researchers [72,74,93,94]. Hoa et al [58] reported that the differences in the protein content of P. ostreatus fruiting bodies could be due to the varying nitrogen content of substrates.…”

“…is related to a number of factors, which may act individually or have interactive effects among them [42,43,71]. 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].…”
