General description
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.
Application
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.

Synapses are fundamental to the normal function of the nervous system. Glia play a pivotal role in regulating synaptic formation. However, how presynaptic neurons assemble synaptic structure in response to the glial signals remains largely unexplored. To address this question

Quality control procedures during food processing may involve direct inoculation of food samples onto appropriate selective media for subsequent enumeration. However, sublethally injured bacteria often fail to grow, enabling them to evade detection and intervention measures and ultimately threaten the
