一般說明
琼脂具有高纯度、低离子含量和低凝胶强度，作为微生物培养基的凝固剂被广泛应用于微生物学。它是从海藻中提取的多糖，主要由琼脂糖组成。琼脂基本上是一种惰性物质，这使它成为微生物培养基的理想材料，因为它不会干扰微生物的生长。琼脂可以固化培养基，使微生物在固体环境中生长，促进不同菌落的形成，并可以选择性地分离特定的微生物。琼脂还用于制备选择性和鉴别性培养基，这些培养基可以提供额外的营养物质或其他化学物质，以选择性地促进或抑制特定微生物的生长。琼脂通过高压灭菌法灭菌，然后倒入培养皿冷却和固化，形成微生物生长的表面。
應用
琼脂通常用作许多微生物培养基的凝固剂，用于各种制药、环境、食品和饮料样品中的细菌、酵母和霉菌的生长和鉴定。

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometric) liquid films. Nevertheless, no experimental
