摘要

The relationship between the chemical composition of nutrient medium, the activity of extracellular lectin of Lentinus edodes [Lentinula edodes] (shiitake), and the formation of pigmented mycelial film in liquid culture was studied, as well as the possibility to regulate lectin activity in shiitake using synthetic components. Also, the formulation of medium, on which the brown mycelial film appears during cultivation was determined. Among the natural amino acids studied as nitrogen sources, and nine divalent metal cations as inorganic additives, L-asparagine and Ca2+ exhibited positive effects with regard to the parameters studied, regardless of the age of culture. Quantum chemical methods and QSAR were applied to test the hypothesis that a differential character of interaction between the studied amino acids and Ca2+ (Mn2+) cations should be related not to the distinct electron structures of Zwitter ions, but most likely to their differing hydrophobicities. The results obtained seemed to make some contribution to the present notion of biochemical processes that give rise to the occurrence of the aforesaid morphological structure of shiitake..
