Hericium Erinaceus Strains

A strain is a pure mycelium culture of edible fungi, used for propagation or cultivation, similar to seedlings of higher plants.

Composition: Consists of pure Hericium erinaceus mycelium, its growth substrate, and packaging containers.

Classification:

• By substrate: Sawdust, cottonseed hull, wheat grain strains.

• By medium property: Solid strains, liquid strains.

• By use: Preserved, experimental, selected, identification, production strains.

• By production stage: Primary (mother), secondary (stock), tertiary (cultivated) strains (also called 1st, 2nd, 3rd-level strains), as regulated by edible fungi strain management rules.

3-Level Strains (per regulations):

1. Primary strains (mother/test tube strains): Pure cultures from spore or tissue separation, grown on test tube slants. Need trans-tube propagation to increase quantity (regenerated mother strains).

2. Secondary strains (stock strains): Derived by transferring mother strains to solid media (e.g., sawdust) in dedicated bottles. 1 test tube mother strain produces max. 6 stock strains; containers: 750ml bottles or plastic bags.

3. Tertiary strains (cultivated strains): Propagated from stock strains, with media close to cultivation substrates. Low-cost, high-quantity, suitable for direct bag cultivation. 1 stock strain bottle can propagate 50 cultivated strain bags.
