Making antibiotic resistant mutants methods
Did you know?
WebThere are two main ways for bacteria to withstand the effects of an antibiotic: To stop the antibiotic from reaching its target at a high enough concentration. To modify or … WebAn excellent way to determine the ability of organisms to produce mutants that are resistant to antibiotic is to grow them on a gradient plate of a particular antibiotic. The gradient plate consists of two wedges like layers of media: a bottom layer of plain nutrient agar and top layer of antibiotic with nutrient agar.
WebSeveral methods were developed to make the isolation of auxotrophic mutants more efficient. Bacteria and other kinds of cells can be treated with various agents to increase the fraction of a bacterial population that contains mutants.
