Agar is widely used in microbiology as a solidifying agent in microbial culture media. It is a polysaccharide derived from seaweed and is primarily composed of agarose. Agar is a mostly inert substance, which makes it an ideal material for microbial culture media because it doesn’t interfere with the growth of microorganisms. Agar can solidify media, allowing microorganisms to grow in a solid environment, which facilitates the formation of distinct colonies and selective isolation of specific microorganisms. Agar is also used in the preparation of selective and differential media, which can provide additional nutrients or other chemical substances to promote or inhibit the growth of specific microorganisms selectively. Agar is sterilized by autoclaving and then poured into Petri dishes, where it can cool and solidify, forming the surface for microbial growth.
애플리케이션
Agar is commonly used as a solidifying agent in many microbial culture media for the growth and identification of bacteria, yeasts, and molds from various pharmaceutical, environmental, and food and beverage samples.

Chemical syntheses and biological evaluation of biscatecholate-monohydroxamate mixed ligand sideromycins utilizing the carbacephalosporin β-lactam antibiotic loracarbef and the fluoroquinolone antibiotic ciprofloxacin are described. The mixed ligand β-lactam sideromycin (1b) had remarkably selective and extremely potent antibacterial activity against the Gram-negative

We report a previously undescribed mechanism for the rugose morphotype in Shewanella oneidensis, a research model for investigating redox transformations of environmental contaminants. Bacteria may form smooth or rugose colonies on agar plates. In general, conversion from the smooth to
