摘要

Inhibitions of lysine analogue S-2-Aminoethyl-L-Cysteine (AEC) on myceliai growth of Pleurotus eryngii, Flammulina velutipes (IM02 ) , Pleurotus tuber-rectum, Pleurotus citrinopileatus, Agaricus blazi and Agrocybe chaxingu (white) were reported. Mycelial growth rate of the six edible fungi was measured when they grew in the minimal medium which comprise different concentrations of AEC(from 4.7 mg/L to 1200 mg/L). The results showed that IC_(50) of inhibition of AEC on myceliai growth rate of Pleurotus eryngii, Flammulina velutipes (IM02), Pleurotus tuber-regium, Pleurotus citrinopileatus. Agaric us blazi and Agrocybe chaxingu (white) in the minimal medium was 1158.8 mg/L,24.8 mg/L,21.7 mg/L,159.4 mg/L,361.8 mg/L and 5754.1 mg/L respectively, which were different significantly. It was concluded that sensitivity of enzymes on end product lysine in the feedback pathway of lysine biosynthesis were different significantly in the edible fungi. The research will be the basis of breeding of high lysine content cultivars of edible fungi.
