A newly developed super chemical, Toxotene, is developed by Evil Science, Inc. While transporting their latest shipment across the Atlantic Ocean, the Toxotene container on the ship springs a leak, spraying Toxotene into the ocean. As an expert biologist, you are tasked with developing a plan to clean up the spill. Being an organic chemical, what type of bacterial species would you use to clean up the spill? Why?
All of the following are possible configurations of bacteria EXCEPT?
a-Monococcus
b-Streptococcus
c-Diplococcus
d-Lactobacillus
Polymyxins are antibiotics that are used in the treatment of Gram-negative bacterial infections. You are given samples of two different types of bacteria. You are told that Bacteria A is Gram-negative bacteria and Bacteria B is Gram-positive bacteria. Describe, in your own words, how you would confirm the bacterial types.

- Suppose 1,000 bacteria are inoculated into a tube of a minimal salt medium where they double once an hour and 10 cells are inoculated into a rich medium, where they double every 20 minutes.

Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution a) In your own words give an introduction to the microbial growth and the effect tempature has. b) In your own words explain the importance of the spectrophotometer in regards to microbial growth. c) In your own words give a hypothesis on how bacteria will react to different temperatures.arrow_forwardSome potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards.
