Study the effect of different concentrations of aqueous extract of Liquorices on the speed of the mycelial growth of Agaricus bisporus, biomass and protein content

Abstract

Study of the effect of aqueous Liquorice extract water to increase the mycelial growth rate, mat dry and protein content. The results revealed that not effect in mycelial growth rate of the Agaricus bisporus on culture medium while in mat dry weight was obtaind the best result with 0.05 g/L licorice extract 51.3 mg/50 ml compared with 37.5 mg/50 ml. The best of protein content with PSA without using Liquorice extract is 22.57% .
