Abstract

Mushrooms are a popular food source as they are highly nutritious and flavorful with a high content of proteins, vitamins, and minerals. Mushrooms could be an alternative solution to the world’s food crisis as they are inexpensive to grow on different types of substrates including waste materials. Pleurotus ostreatus, frequently known as oyster mushrooms, are the second most cultivated mushroom in the world. This species is known for its high protein content and easy cultivation. Oyster mushrooms have the potential to produce protein-rich biomass when grown on various substrates. There is a need to identify substrates that are cost-effective for the commercial production of nutritious oyster mushrooms as the substrates used currently are either costly or inadequate to produce oyster mushrooms in the required quantity or quality. Thus, the effects of 6 different lignocellulosic substrates on the growth and nutritional composition of P. ostreatus were reviewed and analyzed in this article. The substrates included in this review were wheat straw, sugarcane bagasse, corncob, softwood sawdust, hardwood sawdust, and general sawdust. Based on the analyzed data, sugarcane bagasse was concluded as the most suitable substrate to grow P. ostreatus. These substrates contain a high amount of nutrients and are also likely to produce a significantly high yield of oyster mushrooms in addition to enhancing the nutritional quality of the mushroom. However, these findings must be evaluated and confirmed through further research in this field.
