- Abstract
By the method of intermittent leaching aerobic incubation, this paper studied the mineralization of three kinds of microbesderived amino sugar (glucosamine, muramic acid, and galactosamine) in black soil of Northeast China, and the responses to glucose addition and glucose plus nitrogen amendment. The mineralization of the amino sugars was compound-specific. During incubation period, the content of muramic acid decreased by 25-4%, while that of glucosamine decreased by 7-1%, suggesting that bacteria-derived muramic acid was more inclined to be mineralized, compared with fungi-originated glucosamine. However, the mineralized amount of glucosamine (68-4 mg·kg-1) was greater than that of muramic acid (15-4 mg·kg-1). Both glucose addition and glucose plus nitrogen amendment improved the contents of glucosamine and muramic acid significantly, but the effect varied. The mineralization of galactosamine was much slower, and less affected by exogenous substances addition, indicating that galactosamine was more stable in test soil.
