Pleurotus

Pleurotus is a genus of wood-decaying fungi that includes oyster mushrooms. Its species grow on woody substrates and are widely cultivated as food.

Oyster mushroom: An edible mushroom, usually Pleurotus ostreatus, that grows in overlapping clusters on wood. The familiar common name for several cultivated Pleurotus species.
Lignin: A complex aromatic polymer that strengthens plant cell walls and resists microbial decay. Breaking down lignin lets Pleurotus access nutrients locked within wood.
Mushroom cultivation: The controlled production of edible or medicinal mushrooms on prepared growth substrates. Commercial Pleurotus production uses prepared substrates, moisture control, and fruiting conditions.
Pleurotus eryngii: An edible Pleurotus species known as king oyster mushroom, with a thick stem and small cap. It is a commercially important species distinct from the typical oyster mushroom form.
Pleurotus ostreatus: A wood-decaying mushroom species commonly known as the oyster mushroom. It is the best-known species in the genus and a major cultivation crop.
Cellulose: A structural carbohydrate polymer that forms much of the plant cell wall. Pleurotus enzymes decompose cellulose in wood and crop residues.
Spent mushroom substrate: The residual material left after mushroom cultivation has removed much of its usable nutrients. Pleurotus cultivation creates residues that can be reused or managed as agricultural by-products.
Pleurotus citrinopileatus: A yellow-capped edible mushroom species in the genus Pleurotus. Its vivid fruiting bodies demonstrate the genus’s diversity in appearance.
Basidiomycota: A fungal phylum whose members produce sexual spores on specialized cells called basidia. Pleurotus belongs to this spore-producing fungal phylum.
Laccase: A copper-containing enzyme that oxidizes phenolic compounds using molecular oxygen. Pleurotus laccases contribute to lignin modification and plant-material degradation.
