一般描述

琼脂作为微生物培养基的固化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。

应用

琼脂通常用作许多微生物培养基的固化剂,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。
