氨基酸对黑木耳菌丝生长发育的影响

Effect of Amino Acids on Growth and Development of Auricularia auricula

氨基酸对黑木耳菌丝生长发育的影响研究结果表明，在所试浓度下，酪氨酸抑制黑木耳菌丝的生长，Ｔｈｒ、Ｇｌｎ、Ｇｌｙ、Ｇｌｕ、Ｐｈｅ、Ａｒｇ、Ｌｅｕ、Ｌｙｓ和Ｍｅｔ在低浓度下有利于黑木耳菌丝的生长，随着浓度的增加，菌丝生长反受影响；Ａｌａ、Ｓｅｒ和Ａｓｎ黑木耳菌丝生长的适宜浓度分别为０．２％、０．４％和０．２％。天门冬酰胺（Ａｓｎ）在散射光条件下，可促进黑木耳菌丝形成耳基，适宜浓度为０．０５％～０．１０％

The article deals with the effects of amino acids on mycelium growth and development of A. auricula . The results show that all tested amino acids, except Tyr which inhibits the growth of mycelium, can promote growth of auricular in varying degree. At the concentrations range from 0.05 % to 0.4 % , Thr, Gln, Gly, Glu, Phe, Arg, Leu, Lys, and Met are good for mycellium growth at lower concentration. With increasing of concentration, the growth of mycelium is inhibited; the suitable concentrations for growth of A.auricula Ala, Ser and Asn are 0.2 %, 0.4 % and 0.2 %, respectively. Asn can promote the formation of primordial under scattering light at the 0.05 %～0.1 % concentration.
