Some organic materials used for in vitro mycelium growing of Pleurotus ostreatus
Organic mushroom production is limited in Turkey. Only a few mushroom farmers grows organic mushroom on organic stumps. There is no organic spawn production in Turkey. Organic oak sawdust, wheat bran, potato, carrot, mulberry, sweet cherry extracts were used as organic material and Potato Dextrose Agar (PDA) as a control for mycelium growing test on Pleurotus ostreatus. Sawdust without wheat bran gave lower mycelial growth than PDA, however, 150 g sawdust with 20 and 30 g wheat bran (10.81 and 10.88 mm day‑1), 50% potato and 50% carrot (9.28 mm day‑1), 40% mulberry (15.32 mm day‑1), 20% sweet cherry (12.49 mm day‑1) gave higher mycelial growth rate than PDA. Organic mulberry gave the highest mycelial growth rate and could be alternative organic material for in vitro mycelial growth of the P. ostreatus. Although mulberry and sweet cherry extracts had higher mycelial growth, oak sawdust and wheat bran extract could be offered to spawn producer since the extract is available in every season and cheaper than the other materials.
