If you strongly suspect a nutrient agar slant culture is contaminated what method would you use to ascertain whether you are right or not?

You have to make subculture from this slant and after incubation you can observe how many types of microorganisms are present in the nutrient agar slant. If you have one colony shape so you have a pure nutrient agar slant but if you have more than one type of colonies so the nutrient agar slant is contaminated.

Why does this exercise call for an older 5 day culture of bacillus?
Culture age can affect sporulation. Bacteria don't produce spores during culture's growth, but by nutrient depletion.
What do you call a group of cells grown in a nutrient solution from a single cell?
Cell culture is a nearly universally used technique to grow material for biological testing. In cell culture, an original population of seed cells divide under tightly controlled conditions to propagate the culture. All of the daughter cells from the original population are clones.

What is an inoculating medium?
A media which is used to inoculate the bacterium for the culture is a inoculation media. Based on the bacteria, one can use LB media or nutrient broth or any other special media for this. The goal is to let the bacterium grow well from the inoculation culture or colony.
Complex culture media?
Complex culture media is a type of nutrient for growing bacteria that does not have exact composition.

What is the difference between a mixed culture and a contaminated culture?
