Oyster mushroom growing

Oyster mushroom cultivation (Pleurotus ostreatus) is popular due to its ease and rapid growth.

About this subject

Oyster mushroom (Pleurotus ostreatus) is one of the most cultivated edible fungi worldwide, known for its delicate texture and mild flavor. Native to temperate and subtropical regions, it adapts well to various substrates such as wheat straw, sugarcane bagasse, and sawdust. Both home and commercial cultivation have grown significantly because the production cycle is short, ranging from 3 to 4 weeks from inoculation to harvest. Additionally, oyster mushrooms are rich in protein, fiber, and B vitamins, making them a sustainable food alternative.

The most common cultivation method uses perforated plastic bags containing pasteurized substrate inoculated with spawn (mycelium seeds). Ideal temperature for mycelium growth is between 20°C and 30°C, and relative humidity should be kept above 80%. After colonization, fruiting is induced by lowering temperature and increasing ventilation. Mushrooms appear in clusters and should be harvested before the caps' edges start to fray.

Economically, oyster mushroom cultivation provides income for small farmers, especially in developing countries. In Brazil, production is concentrated in the South and Southeast regions but is expanding to other areas. The culinary versatility of oyster mushrooms allows their use in stir-fries, grills, risottos, and even as a meat substitute in vegetarian diets. Interestingly, Pleurotus ostreatus is also known for its ability to degrade pollutants, being used in bioremediation processes.
