RESEARCH ON HEAT RESISTANT LION' S MANE MUSHROOM CULTURE

Abstract

Lion's mane mushroom (Hericium erinaceus) is a mushroom with many important nutritional and medicinal values. The creation of a mutant lion' s mane mushroom with heat tolerance, strong growth and suitable for tropical climate conditions is a very useful breakthrough in scientific research. However, studies on the cultivation of heat resistant lion's mane mushroom in Vietnam are still very limited. The growing environment is quite complex and requires many secondary factors that make the production of this fungus unpopular. Therefore, it is extremely important to research and investigate to simplify the culture environment while still achieving high yield. Stemming from the above urgent reasons, this research was carried out to determine the suitable culture for propagation of heat-resistant lion's mane mushroom as well as to investigate the composition of the propagation medium to produce fruiting bodies for this fungus on sawdust background. The results showed that, for the propagation medium of heat-resistant lion's mane mushroom, the rice seed medium supplemented with 6% corn bran and 1% KH2PO4 mineral for fast-spreading silk was the most suitable source of nutrients. Regarding the spinning speed on the embryo sac, the culture with rubber sawdust and 10% corn bran gives the fastest speed. This research is a necessary premise for the mass production of lion's mane mushroom later.
