Extensive clinical studies, primarily in Japan, have clearly demonstrated that mushroom have medicinal and therapeutic value, by injection or oral administration, in the prevention/treatment of cancer, viral diseases (influenza, polio), hypercholesterolemia, blood platelet aggregation, and hypertension,and most of the studies are on Ganoderma sp.
many of the active substances which include polysaccharides (e., β- glucans), nucleic acid derivatives (the hypocholesterolemic eritadenine), lipids, peptides, proteins, and glycoproteins, have been isolated and identified. Some of the mechanisms of activity have been elucidated, e., antiviral activity via stimulation of interferon production in the host. Additional medical claims which were less well documented may nonetheless have some validity and merit further study. [1] Reishi has long been studied in long time by scientists because of their great use, and most studies are done on Ganoderma lucidum - the most popular type of Reishi.
Meanwhile, not much research has been done on the black Reishi or Ganoderma subresinosum , which is not difficult to cultivate, and has high practicality. Vietnam is a country of abundant raw materials and human resources, which are suitable for growing mushrooms, so it can contribute to 1 sustainable economic development. For that reason, I chose Ganoderma subresinosum as the research object for this thesis. To grow Ganoderma subresinosum or any other fungus, besides choosing varieties and farming methods, an factor is very interested and focused on what is the enviromental condition .Depending on the location and climate of each country, it is possible to determine the most suitable farming conditions,which have not been studied much.
If the best growing conditions are determined, the best black Reishi mushroom strain will be produced, so this is considered a prerequisite step for the isolation and cultivation of black Reishi strains collected from heaven. As a result we do the topic “Determination of suitable cultural conditions for the growth of black lingzhi mushroom (Ganoderma subresinosum)” 1.2 Objective Research and determine the most suitable growing conditions for Ganoderma subresinosum strain, including temperature, pH, agar media and different nutritional supplements.3 Requirement Evaluate the growth of Ganoderma subresinosum on different levels of temperature, pH and agar environment to determine the optimal environment for Ganoderma subresinosum strains. Evaluate the growth and development of Ga21 strain on different sawdust substrates and then select the most potential substrate for production. 2 CHAPTER II: LITERATURE REVIEW2 2.1 The situation of research in the world and Viet Nam 2.1 The situation of research in the world Nowadays, more than 2000 species of mushrooms have been identified [2].
Among known mushroom species, approximate 80 edible and medicinal mushrooms such as oyster mushroom, straw mushroom, wood ear mushroom, and shiitake mushrooms have been successfully cultivated. Due to scarcity in nature, Ganoderma sp. are artificially cultivated in solid culture to meet demands for medicinal herbs and international markets. In Taiwan, Peng (1990) and Hseu (1992) collected and cultivated more than 10 different Ganoderma species.
In Korea, Ganoderma sp. also occupies a significant market share and pays special attention to the Ancient Lingzhi hay Artists conk species with its high anti-tumor effect. Yet China is still recognized as the world's largest center for growing and producing Reishi mushrooms [3]. According to the statistics of Moore and Chiu (2000)[4], the total global output of Reishi in 1997 reached 4300 tons, the output of China was 3000 tons.
According to Wang X. has been cultivated in China since 1621. Ganoderma sp was first reported from China by Teng (1934)[6], with four species including G. lucidum and one variety.
Later, many researchers extensively studied Chinese Ganodermataceae and introduced more than 100 species in four genera: Ganoderma, Amauroderma, Haddowia and Humphreya (Zhao & Zhang 2000, Wu & Dai 2005, Cao et al. Ganoderma was accepted as the scientific binomial of “Lingzhi” in many reports on Chinese edible and medicinal mushrooms, but it was recently described as Lingzhi based on strong molecular and morphological evidence (Cao et al. 2012, Dai et al. Mycochemical and other studies reported different species numbers in the genus Ganoderma (Peng et al.
2014, Yan et al. However, the majority 3 of Ganoderma species reported from China have not been subjected to systematic studies (Baby et al. By 1936, Zenzaburo Kasai and Yukio Naoi successfully cultivated Ganoderma sp. at Tokyo Agricultural University, Japan.
Since then, the technology of cultivating Lingzhi in Japan has developed strongly, the output from 1979 - 1995 has increased 40 times [14]. Japan is the first country to successful cultivation of Ganoderma sp. and the scientific research and Preparation of medicinal products are ranked among the top in the world. Korea is also a country with highly developed Reishi mushroom production technology.
The situation of research in the Vietnam In Vietnam, the Institute of Medicinal Materials - Hanoi successfully cultivated Ganoderma (Chinese variety) in 1978. Nine years later, in 1987, scientists from the University of Natural Sciences chose Lingzhi variety growing wild in Lam Dong mountain forest to propagate and put into production in Ganoderma farm of Central Pharmaceutical Enterprise 24, achieving good results in 1988. The Vietnamese Medicine and Pharmacy who succeeded Ly Thoi Tran discovered the use of Lingzhi mushroom such as: Le Quy Don pointed out that Lingzhi is: "The source of rare products of Dai Nam land", 200 years ago, such as Hai Thuong Lan Ong, Le Huu Trac proposed the motto "Men pharmacy to cure the Men" using Linh Chi in a number of remedies (according to Dinh Xuan Linh et al, 2012).[15] Several studies have been reported regarding the taxonomy and distribution of Vietnamese Ganodermataceae. Vietnam possesses 27 species of the Ganoderma genus; however, the classification and distribution of the Ganoderma genus in Vietnam continues to be studied.
In a 2013 report by Nguyen et al.,[16] 43 species of the Ganoderma genus were identified in the 4 Highlands of Vietnam. Five of these have been successfully cultivated in Vietnam including G. subresinosum, and one of these the G.lucidum species is most commonly cultivated.
