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。它还用于制备选择性和差别化培养基，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。

The emergence of Staphylococcus aureus strains resistant to 'last resort' antibiotics compels the development of new antimicrobials against this important human pathogen. We found that propyl 5-hydroxy-3-methyl-1-phenyl-1H-pyrazole-4-carbodithioate (HMPC) shows bacteriostatic activity against S. aureus (MIC = 4 μg/ml) and rescues Caenorhabditis elegans from
