Support your answer using computation-based judgment. Encircle/box your final computed answer in your solutions along with a declaration of TRUE or FALSE for each given situation. UHT-pasteurized milk sample X which was spread-plated in quadruplicates yielded the following bacterial colony counts: 23, 20, 35 and 41 CFU/plate at a dilution factor of 100. Therefore, the milk sample will pass laboratory standards if the quality control laboratory sets the total microbial limit as: “not to exceed more than 30,000 CFU/mL of milk sample”.

Explain. What are two possible reasons for choosing a bacteriostatic treatment over a bactericidal one? Name at least two factors that can compromise the effectiveness of a disinfecting agent.
TSI Test plz answer all questions Why does TSI contain less glucose than sucrose or lactose? Does an acidic slant indicate that the microbe is a coliform? Explain your answer. What is the function of iron in this medium? Production of H2S by bacteria growing anaerobically in the intestines is common. Some H2S is absorbed into the circulation and some is expelled as intestinal gas. Less commonly, in certain individuals, H2S producing bacteria can live in the plaque built up around their teeth. What undesirable effect might that lead to? conclusion
