How can you tell if a bacterium can metabolize casein in the casein digestion test?
What test could you use to determine if your unknown bacterium was Staphylococcus aureus or Staphylococcus epidermidis? O Mannitol Salt Agar O Oxidase O Catalase Urease Citrate
If you suspected that your unknown bacterium is either Pseudomonas or Proteus, what test could you use to differentiate between the two? O Citrate O Urease Indole O Oxidase O Catalase
Yield calculations, to decide between using a bacterium and a yeast for your fermentation, so you decide to use your bioprocess engineering know-how to make some estimates. Assuming the following overall biomass reactions and an equal respiratory quotient (RQ) of 0.5 for both organisms, which organism will most efficiently use its substrate to create biomass? Calculate yield coefficients (in terms of mass) to justify your answer. Assume MWsubstrate = 180. Bacterium (MWbiomass = 25.5): Yeast (MWbiomass = 24):
Which statistical test to use to compare an antibiotic used on two different organisms? (i.e. Streptomycin was used on e.coli and s.aureus and we want to check if it's more significant on e.coli/s.aureus)
please (TYPE) the answers, i do not want by hand 1)Beggiatoa sp, 2) green sulfur bacterium , 3) sulfate-reducing bacterium. A) what does 1,2,3 tell you about the organisms and metabolism? B) what is your organism's electron acceptor and electron donor?
What is an E-test strip and are they more or less advantageous to use than the standard antibiotic sensitivity disks? Why? For which organisms are the E-test most useful?
Using the Annual Report of any company of your choice answer the following questions in the Discussion: 1) Did your company have any preferred stock at year end? 2) How much of the company's common stock was outstanding at year end? 3) Did the company pay any cash dividends during the year? 4) Compute the basic earnings per share for the company. 5) What method does the company use to report net cash flows from operating activities?

A clinical researcher performed a modified Kirby-Bauer assay on a bacterium cultured from a patient. The following is a summary of the assay performed: The clinician spread the surface of several Mueller-Hinton agar plates (a media type containing beef extract, casein, and starch) with the bacterial culture using aseptic technique. Next, they applied sterile antibiotic disks, each containing a different antibiotic to the surface of the plates. After the agar plates were incubated overnight, the clinician measured the diameter of...
Are they organisms; that is, are they alive? What role did viruses play in the evolution of life? What are their distinctive biological characteristics? How can particles so small, simple, and seemingly insignificant be causing disease and death? What is the connection between viruses and cancer?
