Chapter 26, Problem 5U
Summary Introduction
Introduction:
Carbon is found in two forms in the organic matter of living organisms: stable form of “carbon 12” and the radioactive isotope “carbon 14”. At particular period of time in lifetime of living organism, the ratio of these two carbon forms in the tissue is approximately same. But after the death of an organism the ratio of “carbon 12” to “carbon 14” show changes due to the decay of carbon 14 to nitrogen 14. Thus, isotope decay is used to estimate the age of fossils.

- In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward9.
