Use of Different Agro-wastes in the Cultivation of Pleurotus ostreatus (Jacq.) Kummer

Abstract

Agro-wastes are abundant in both rural and urban areas and when carelessly disposed off to the environment by dumping or burning, they lead to environmental pollution, and consequently to health hazards. Growing of edible mushroom on these wastes can contribute to decrease in environment pollution. This work investigated the growth and yield of Pleurotus ostreatus on different agro-wastes: plantain midrib (PM), corn straw (CS), sugarcane bagasse (SB) and their combinations (PM+CS, PM+SB, CS+SB, CS+PM+SB) with a view to finding the best substrate for the growth of P. ostreatus. The experiment was carried out using completely randomized design with seven treatments and three replications. Results revealed that mycelia growth period and days to pinhead formation were faster in corn straw (7 and 11 days, respectively from the day of inoculation), this was followed by CS+SB (8 and 12 days, respectively) while CS+PM+SB recorded the longest days (13 and 17, respectively). Stipe length ranged from 2.6 cm in PM to 3.3 cm in CS+PM while the pileus diameter was between 3.3 cm in CS and PM and 4.3 cm in PM+SB. Number of fruiting bodies, fresh and dry weights of the mushroom were significantly higher in CS than in the other substrates. The least number of fruiting bodies, fresh and dry weights were recorded in CS+PM+SB.

Food Waste Originated Material as an Alternative Substrate Used for the Cultivation of Oyster Mushroom (Pleurotus ostreatus): A Review

“…Huang et al [59] utilized rice straw, while Wiafe-Kwagyan et al [71] additionally used rice bran and husk mixtures supplemented with different percentages of CaCO 3 . Corn straw and sugarcane bagasse were mixed (50%:50%) in combination with plantain midrib in order to find out the best substrate for cultivation [72], while corncob alone and in the mixture with finger millet straw and bamboo waste was used in the following study [73].…”

“…First of all, the studies include biological efficiency of substrate utilization (BE) as the most valuable parameter that involves the yield of the cultivated fruiting bodies per kg of substrate on a dry weight basis [27][28][29]32,36,37,39,52,53,55,58,59,65,66,68,70,71,73]. This parameter is followed with mycelium running rate in bags (mm/day) [27,28,52,70], total mushroom yield (g) [27,28,32,37,54,58,65,[67][68][69][71][72][73], time required for completion of mycelium running (days), time required for primordia appearance and harvesting (days) [27][28][29]35,37,39,54,58,60,64,70,72,73].

On the other hand, some investigations included economic yield (g/bag) after removal of inedible parts of the mushroom and organic matter loss [36,53,54,68], as well as mushroom weight (g) [29,32,36,39,70], pileus and stipe diameter (cm) and stipe length (cm) [36,39,[52][53][54]66,[70][71]…”

Effects of Different Substrates on the Growth and Nutritional Composition of Pleurotus ostreatus: A Review

“…This could be influenced by several factors such as the types of mushroom species, the used substrate, and the level of nitrogen available in the growth substrate (Belletini et al 2019). Currently, the number of studies that focus on the utilization of lignocellulosic substrates are increasing (Iwuagwu et al 2020;Nongthomban et al 2021). Ganash et al (2021) demonstrated that Pleurotus species are very effective in breaking down lignocellulosic residues making it a suitable mushroom to be cultivated on lignocellulosic substrates (Figure 1).…”

“…This organic bulk can pollute the environment in many cases especially the lignocellulosic components as they are not readily degraded by organisms (Hatakka 1994;Philippoussis 2009). Waste materials from agriculture and industry can be used to grow mushrooms (Abid et al 2020;Iwuagwu et al 2020). Mushrooms are macrofungal fruiting bodies that are extremely rich in flavor and do not have high calories but are rich in vitamins, minerals, and proteins (Mubasshira et al 2020).…”
