Abstract:

In the article, the effects of three kinds of organic acid from citric acid, tartaric acid and succinic acid and three kinds of amino acid from alanine, tyrosine and arginine in different concentration on the growth of Agaricus bisporus were studied by the solid and liquid culture methods. The growth parameters of the clony diameter, extracellular protein content, mycelium dry weight, intracellular polysaccharide content, peroxidase activity and reducing sugar content were analyzed in treat groups. The results showed that the growth of Agaricus bisporus could be promoted by adding 0.04% citric acid, succinic acid, tartaric acid and arginine. Compared to the control in the medium, the mycelium dry weight was highest by adding succinic acid, it increased 131%; the extracellular protein content was highest by adding arginine, it increased 151%; intracellular polysaccharide content and peroxidase activity of Agaricus bisporus were the highest value by adding citric acid, they increased 21% and 146% respectively. But higher concentration organic acid and amino acid would inhibit the growth of Agaricus bisporus.
