一般描述

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。

应用

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。

Arylamine N-acetyltransferase-1 (NAT1) is an enzyme that catalyzes the biotransformation of arylamine and hydrazine substrates. It also has a role in the catabolism of the folate metabolite p-aminobenzoyl glutamate. Recent bioinformatics studies have correlated NAT1 expression with various cancer subtypes.
