You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative.
6) What would be the last reagent you use to identify the bacteria? 7) What type of visual aid you need to help you see the bacterial samples clearly? 8) After the use of what reagent, you will be able to decide if you have a Gram positive or Gram negative bacteria?
**Please give the answer**
during inoculation, the bacterial culture tube is always held at an angle and the lid of the Petri dish is slightly open. Explain the purpose of these steps briefly.
A lab technician is working with a bacterium in pure culture (in 5 ml of liquid media in a test tube). The bacterium is a mesophile that can infect humans. Which of the following is NOT true (with regards to temperature conditions for this bacterial culture)?
Lowering the temperature to -10 deg C for at least an hour will likely kill all the bacteria.
Placing the tube at 37 deg C will likely facilitate rapid growth of the bacteria.
Raising the temperature to 90 deg C for at least an hour will likely kill all the bacteria.
Placing the tube at 4 deg C will likely slow or halt growth of the bacteria.
