Summary Introduction

To determine: The similarities and differences between strict aerobes, strict anaerobes, and facultative anaerobes.

Introduction: Micro-organisms can be classified into various categories based on the requirement of oxygen for their survival. These categories are strict (obligate) aerobes, strict (obligate) anaerobes, facultative anaerobes, aerotolerant anaerobes, and microaerophiles.

Explanation of Solution

Aerobes and anaerobes (facultative or strict) both perform cellular respiration and utilize glucose as a substrate or starting molecule to produce ATP or energy. However, the amount of ATP released by aerobic respiration is much more as compared to that of anaerobic respiration.

The differences between strict aerobes, strict anaerobes, and facultative anaerobes are as follows:

S. No.CharacteristicsStrict aerobesStrict anaerobesFacultative anaerobes
1.Oxygen requirementThe organisms that strictly require oxygen in order to grow are strict aerobes.The organisms for which oxygen is toxic, and they only grow under high reducing intensity or absence of oxygen are strict anaerobes.The organisms that can grow under both aerobic and anaerobic conditions are facultative anaerobes.
2.Terminal electron acceptorThey use molecular oxygen as a terminal electron acceptor.They use molecules such as sulfate (SO42-), nitrate (NO3-), and ferric iron (Fe3+) as terminal electron acceptors.They preferentially use molecular oxygen as terminal electron acceptors but can also use sulfate (SO42-), nitrate (NO3-).
3.ExamplesPseudomonas aeruginosa and Mycobacterium tuberculosis.Clostridium, and PropionibacteriumEscherichia coli, Salmonella, and Staphylococcus aureus.

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 16
