Influence of Algae Oligose on Growth of Pleurotus eryngii

[Objective]The research aimed to study the influence of the marine active substances of algae oligose on Pleurotus eryngii. [Method]By adding different concentrations of alage oligosaccharides into medium,the growth rate of mycelium which grew on the solid plate culture of Pleurotus eryngii,dry weight of fermentation mycelium,and the cellulase activity in fermentation were measured. [Result]When the concentration of the algae oligosaccharide was 0. 001 mg /ml,the growth rate of mycelium,the biomass of mycelium and the cellulase activity were more different than other group.[Conclusion]The effect of algae oligosaccharide with low concentration on the growth of Pleurotus eryngii was great.
