Why do microorganisms feed on agar?

microorganisms do not feed on agar for the same reasons why people don't eat cardboard: nutritional value is simply not worth the effort. Scientists use this characteristics when they need to grow various microorganisms for research. Because AGAR has no nutritional value, scientists can accurately control available nutrients in agar plates used for cultivation organisms. This gives them a better understanding of the microorganisms they examine and allows them to ensure that only certain types of organisms are allowed to grow. Rod Gelidium is particularly popular for commercial sources of agar. This gelatin material has a number of interesting features that made it useful to people; For example, agar is often used as a food additive to hold food together without adding calories. It is particularly common in dairy, where it is used as a thickener. Scientists do this by creating an agar plate, a bowl filled with agar and a source of nutrition. Microorganisms are often very picky about what buysDou eaten, and the use of a controlled nutrition source ensures only certain types of microorganisms. Undesirable interllocks have nothing to eat because they can't feed agar.

Scientists do not use this substance because microorganisms cannot feed on agar. It is also useful because it creates a comfortable gel layer that allows them to clearly visualize the organisms that grow. In addition, it provides a suitable substrate for microorganisms on which it can grow and creates small clusters known as a colony that can easily be selected for further research and other use.

growing microorganisms is hard work. Finding a source of nutrition that satisfies the body often requires several attempts, and the formula may need to be refined constantly, and in the growing environment further adjustments to light, temperature and humidity are performed. Several scientific companies sell basic sets of agar boards with common cultTivative media, but advanced laboratories often have to combine their agar boards to satisfy the needs of their research items.

Because microorganisms are not feeding agar, agar plates are also inherently sterile until nutrients are added. Maintaining a sterile environment is decisive for many scientific research industries because scientists want to make sure they know exactly what they are studying. Because microorganisms feed on agar, scientists know that their research is removed the main potential variable when they use properly prepared agar boards.
