Effects of Exogenous Substances on Growth of Polyporus umbellatus Mycelium and Its Polysaccharide Content
To explore the effects of diverse exogenous substances at different concentrations on the growth of
Polyporus umbellatus
mycelium and polysaccharide content and screen out the optimal growth condition for
P. umbellatus
mycelium, so as to provide a reference for its large-scale artificial cultivation.
Method
2
P. umbellatus
mycelium was cultured in media containing different exogenous substances using the method for fungal culturing in plate. The growth rate of the mycelium was judged by the colony diameter and the polysaccharide content was determined by the phenol-sulfuric acid method.
Result
2
The high-dose cyclic adenosine monophosphate, 6-benzyl aminopurine (6-BA), gibberellic acid (GA), 2,4-dichlorophenoxyacetic acid (2,4-D), vitamin (V) B

all promoted the growth of
P. umbellatus
mycelium and elevated polysaccharides content. By contrast, indole acetic acid (IAA), VC, and VB

inhibited its growth, with the most obvious inhibition detected in the high-dose VC group. IAA and VB

both reduced the polysaccharide content, whereas the high-dose VC significantly increased the polysaccharide content. Cyclic adenosine monophosphate, 6-BA, GA, 2,4-D, VB

Conclusion
2
The growth of
P. umbellatus
mycelium and polysaccharide accumulation can be regulated by adding exogenous substances to the culture medium.
