Abstract

Antler-type fruiting bodies of Ganoderma lucidum have been cultivated successfully in several countries worldwide. In Vietnam, there is little information related to this product. In this study, we found optimal substrate conditions for developing antler-type fruiting bodies: sawdust with 5% corn bran, 5% rice bran, 1% calcium carbonate, and 3% bean flour. The results show that the kidney-shaped reishi fruiting bodies under normal culture (CT1) changed to antler-type fruiting bodies formed under dark conditions (CT2), and typical antler-type fruiting bodies under light and airless conditions (CT3) or under dark and airless conditions (CT4). In CT3 and CT4 conditions, reishi mushroom bodies did not produce spores and were reddish-brown and shiny. In the form of antler-type fruiting bodies, Ganoderma has the highest dry yield in CT3 conditions, with a fruiting body length of 33 cm and a yield of 28.02 g/bag. However, the content of water-soluble polysaccharides was highest when the fungus was grown under the CT4 conditions, reaching 0.47 mg glucose/g of crude water-soluble polysaccharides.
