Starting with a single bacterium you would expect to have 16 bacteria after 4 generations
Explanation: Bacteria reproduce via binary fission. This process produces two bacteria from one parent cell. A single bacterium (say zeroth generation) produces two bacteria after one generation, which can then produce four bacteria in the second generation, which, in turn, can produce eight bacteria in the third generation and in the fourth generation this 8 bacterium would divide to produce 16 bacterium. Ideally given by 2^n = 2^4 = 16.

You have an unknown bacterium. You decide to plate it on an MSA blate. After 24 hours the plate turns from red to yellow. This means Your bacteria can ferment glucose to lactose The bacteria could be gram negative since it grew on MSA plates You do not need to test coagulase since it is not likely to be Gram positive O Your bacteria can ferment mannitol Your bacteria can ferment galactose

MICROBIO HELP: You want to grow up some bacteria to bring to class to show your friends, and you want to have enough to give everyone in the class 100 bacteria. If you are starting with only 5, how many generation times should you allow so you will have enough? (assume there are 130people in the class). If you knew it took 1 hour and 39 minutes to grow all your bacteria, what is the generation time? Helpful information provided:...

Membrane fluidity for bacteria is critical. What type of fatty acids would you expect bacteria to synthesize as growth temperature increases? Why type of fatty acids would you expect bacteria to synthesize as growth temperature decreases? Why cannot bacteria simply synthesize the same type of fatty acids regardless of temperature?

You have discovered an enzyme for turning lead into gold (Pb2Au) in the extinct bacterium Alchemistia imbecilis. You need to express the protein with the Mgk promoter. Outline the steps you would use to construct a single plasmid containing all of the following characteristics to create bacteria that might make gold from lead: 1) the Mgk promoter directly upstream of the Pb2Au gene (and in the same orientation), 2) the intact kanr selectable marker, 3) the Mgk::Pb2Au promoter::gene combination disrupting...
