Oyster mushroom growing

Oyster mushroom (Pleurotus ostreatus) cultivation on organic substrate, one of the most farmed species worldwide due to its ease and nutritional value.

About this subject

Oyster mushroom, also known as Pleurotus ostreatus, is one of the most popular edible fungi globally. Its cultivation stands out for simplicity and low cost, feasible on small scales or in commercial systems. Typical substrate includes agricultural residues like wheat straw, sawdust, or coffee husks, enriched with nutrients. Growth occurs in bags or trays, under controlled temperature (15°C, 25°C) and high humidity.

In Brazil, oyster mushroom farming has grown, especially in states like São Paulo and Paraná, driven by demand for healthy foods and protein alternatives. Besides its mild flavor and tender texture, oyster mushrooms are rich in protein, fiber, B vitamins, and minerals like potassium and selenium. Studies show antioxidant and immunomodulatory properties, making it a functional food.

A fun fact: oyster mushrooms can be used in various dishes, from stir-fries to soups and risottos. Home cultivation is possible with DIY kits. Harvesting occurs in cycles of about two to three weeks after inoculation, when cap edges begin to curl upward.
