Scientific research on microorganisms needs more than conventional research ideas and tools. When it comes to tools, many people are bound to think of microscopes first. But the microscope is only suitable for observation and if biochemical analysis is to be carried out, the role of Agar is even more important. If you have been to the microbiology lab, you will find that the most commonly used experimental tool is a petri dish, which is covered with nutrient-rich Agar. Each bacteria can grow independently on the surface of Agar in a flora visible to the naked eye. Each flora contains thousands of identical bacteria, which is called a clone in biological terms. Because Agar is semi-solid, the position of the bacteria is fixed and cannot move freely between the flora, which is tantamount to cloning and amplifying one bacteria to a large enough amount without being contaminated by other bacteria. Only in this way can scientists carry out biochemical analysis.
