The mushroom is the fruiting body of the macrofungi. Approximately 14,000 described species of
fungi produce fruiting bodies that are large enough to be considered mushrooms using our definition,
which states that “the mushroom is a macrofungus with a distinctive fruiting body that can be either
epigeous (aboveground) or hypogeous (underground) and large enough to be seen with the naked
eye and to be picked by hand.” According to this definition, in contrast to other definitions,
mushrooms can be Ascomycetes, grow underground, have a nonfleshy texture, and need not be
Objective of topic To conduct research on some biological characters of strains of King Oyster and Yunzhi mushrooms to identify best developing strains in climatic condition of Vietnam, and at the same time, to set up spawn production technologies for mushroom strains of liquid spawn in order to improve production efficiency for edible and medicinal mushrooms
Basidiomycetes constitute a natural source of biologically
active metabolites. Many basidiomycetes have
been classified by the National Cancer Institute of the
United States as antitumor agents exhibiting an immunomodulatory
activity.1 The therapeutic activity is
mainly related to polysaccharides or protein-bound
polysaccharides, such as glucans, heterogalactans, and
glucanproteins, which are present either in the mycelium
or in the fruit body.2–6 Among these polysaccharides are
b-D-glucans, which are of particular interest because of
their pharmacological properties.
Chapter 31 introduce to fungi. This chapter list the characteristics that distinguish fungi from other multicellular kingdoms, discuss mycorrhizal fungi, describe the processes of plasmogamy and karyogamy, describe the processes of plasmogamy and karyogamy,...and another content.

In this paper, a biologically active substance of Lingzhi mushroom was studied. The optima process seperating (1,3)-B-D-glucan from Ganoderma lucidum has been formed and the molecular weight of the preparation is estimated. The structure of (1,3)- -D-glucan unit and its properties are characterized by using HyperChem 7.02 software.
