INTRODUCTION Bacteria can be conserved in a lab in many different ways, but the most common way is a suspension culture. A suspension culture is when the cells are grown in a sterile, full of supplements, broth. The broth allows the cells to divide and grow easily and will later turn into broth turbid. When culturing microorganism, the culture has to be completely pure. The best technique to preserve the culture pure is by avoiding bacteria in the environment to contaminate the culture, and to prevent the culture in contaminating the environment.
There are many different ways to prevent microbial growth. The most common form to destroy microbial growth is by using antibiotics. Antibiotics are substances produced by living organism, to kill or inhibit the growth of other organisms (Lab Sheet, 5). Antibiotics are normally altered to fit specific characteristics that require a natural form. Antibiotics can also be changed to reduce toxicity in an organism. Antibiotics are essential to combat bacteria. In this experiment, the bacterium that is being texted is Escherichia coli also known as E.coli. E.coli is a bacterium that normally lives in the intestines. E.coli it is not harmless, but when infected it can cause diarrhea or other intestinal problems (Mayo Clinic, 2014). The antibiotic that is…
