Adsorption of melanoidin to the mycelia of Aspergillus oryzae Y-2-32

Autoclaved mycelium of Aspergillus oryzae Y-2-32 adsorbed melanoidin, especially lower molecular weight fractions, and the degree of the adsorption was influenced by the kind of sugars utilized for growth.The melanoidin-adsorbing ability of mycelia was repressed by a high concentration of salt. Furthermore, it decreased to half the initial level on washing with a 0.1% Tween 80 solution and was entirely lost on washing with a 0.1% sodium dodecylsulphate solution.
