随着新陈代谢作用的进行，以氨基糖为代表的微生物细胞壁残留物不断在土壤中积累，并进一步参与土壤碳、氮循环。

During the metabolism, the microbial residues represented as amino sugars were accumulated in soil and probably concerned in further carbon and nitrogen cycling.

高浓度的糖会穿过微生物的细胞壁吸取其“生命之水”，从而使其脱水。

High concentrations of sugar will suck the microbe's vital water right through its cell wall, causing it to dehydrate.

支原体属支原体属大量寄生的、致病的微生物，它们没有真正的细胞壁，呈格兰氏阴性并且生长时需要类固醇（比如胆固醇）。

Mycoplasma that lack a true cell wall, are gram-negative, and need sterols such as cholesterol for growth. In human beings, one species is a primary cause of nonbacterial pneumonia.
