Question

You have developed a new food additive that is supposed to help food to stay fresh longer as it sits acarcinogen). You before you can use this additive you must prove that it is safe for human consumption (i.e. it is no.w food additive? perform an Ames test as described below. Based on the results what can you conclude about your ur new His bacteria are mixed with the food additive His bacteria are mixed with liquid control Bacteria are plated onto glucose-salts medium without liver extract Bacteria are plated onto glucose-salts medium with liver extract Bacteria are plated onto glucose-salts medium without liver extract Bacteria are plated onto glucose-salts medium with liver extract 4 colonies are counted after incubation 89 colonies are counted after incubation 6 colonies are counted after incubation 3 colonies are counted after incubation

Explanation / Answer

Based on the Ames test performed, the histidine negative bacteria when mixed with food additive along with glucose-salts and liver extracts providing all the essential micro and macronutrients 89 colonies are formed after incubation whereas in the liquid control medium with and without liver extract very few colonies were able to grow due to natural mutation. Hence, from the Ames test performed we can conclude that the new food additive formulated is carcinogenic and is not suitable for consumption.
