Potential Enhancement in The Nutritional Value of Local Agro-Waste Through Cultivation of Pink Oyster Mushroom (Pleurotus djamor)

Abstract

The present study aimed to examine the effect of locally available agro-industrial wastes on the growth and productivity of pink oyster mushrooms (Pleurotus djamor) and the potential use of substrates as animal feeding based on its compositional change following mushroom growth. A total of three substrate formulations labeled OPF (80% oil palm frond), CS (80% corn straw), and OPFCS (40% oil palm frond + 40% corn straw) were prepared. Aside from the earliest mycelium completion, pinhead formation, and fruiting bodies maturation, CS and OPFCS exhibit the best total yield, dry weight, and biological Efficiency. On the contrary, P. djamor grown in OPF resulted in the minimum in most of the parameters measured. Therefore, CS, single and in combination with OPF could be utilized as an alternative growing media for the cultivation of P. djamor. The analysis of chemical compositions showed that the growth of P. djamor significantly reduced the crude fiber (CF) and increased the crude protein (CP) content of the mycelium-treated substrate. In contrast, THE CP content of the spent is unchanged or relatively lower than that of the initial substrate. It can be concluded that compared to the spent, mycelium-treated substrate had higher values of being used for animal feeding.

Edible Mushrooms of Peri-Urban Kichwa Communities in the Andes-Amazon Piedmont, Ecuador

“…In the case of Pleurotus djamor, fruit bodies grow very fast and remain edible for just about two or three days, making them difficult to collect in the right state of softness and texture for consumption. This species requires much local attention given its good quality nutrients and other molecules related to improving health such as antioxidants, tannins, flavonoids, terpenoids (Nayak et al 2021) with the advantage of having already a technology of cultivation developed in other parts of the world, that includes the use of crop wastes such as maize, coffee, rice and palm (Hutabarat et al 2022; Vega et al 2022), that also grow in these communities.…”
