In the polluted soil, between DOM and amino sugars, especially DOM and muramic acid, there are significant relationships. 污染土壤中土壤溶解性有机质与氨基糖,尤其是与胞壁酸之间存在显著的相关性。
It was composed of lipid ( 17 1%), polysaccharide ( arabino galactan 46 3%), and mucopeptide, which was mainly composed of alanine, glutamic acid, DL α ε diaminopimelic acid, glucosamine and muramic acid. 含有类脂化合物(171%)、多糖(阿拉伯半乳聚糖463%)、粘肽(主要为丙氨酸、谷氨酸、二氨基庚二酸、葡萄糖胺、胞壁酸);
Combining ridge and no tillage ( RNT) will help to improve soil aggregates in the microbial biomass and soluble organic carbon content. ( 4) Fungal and bacterial biomass was estimated by measuring the amount of ergosterol and muramic acid, respectively, in the samples. 垄作免耕有利于提高土壤团聚体中的微生物生物量及可溶性有机碳含量。(4)采用麦角固醇和胞壁酸标记法测定各级团聚体中真菌和细菌的生物量。
