Green tea-flavored yōkan, a popular Japanese red bean jelly made from agar A blood agar plate used to culture bacteria and diagnose infection. Agar (/ ˈ eɪ ɡ ɑːr / or / ˈ ɑː ɡ ər /), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from “ogonori” and “tengusa”.
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens.

Contamination on an agar plate. An agar plate is a Petri dish that contains a growth medium solidified with agar, used to culture microorganisms. Sometimes selective compounds are added to influence growth, such as antibiotics. [1] 96 pinner used to perform spot assays with yeast, fungal or bacterial cells
Petri dish/agar plate: to act as a supporting container to hold the culture medium in Platinum wire loop: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc.; sterilized by flaming to red hot before use Pre-sterilized disposable container: specimen collection
Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar, resulting in the formation of a visible precipitate when they interact.
Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample. From here, the plates are rotated to ensure the samples are uniformly mixing with the agar.
This includes water, a source of energy, sources of carbon, sulfur, nitrogen, phosphorus, certain minerals, and other vitamins and growth factors. A very common type of media used in microbiology labs is known as agar, a gelatinous substance derived from seaweed. The nutrient agar has a lot of ingredients with unknown amounts of nutrients in ...
Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains ( mass/volume ): [ 1 ] 0.5% peptone – this provides organic nitrogen
