As a Microbiologist working on a bioremediation project, you are torn between 2 choices for remediation of soil contaminated with jet fuel. Your first option is to fertilize the soil with nitrogen and phosphorus for possible promotion of growth hydrocarbon-degrading microorganisms. For your second option, there is a possibility of using a new commercial microbial inoculum containing hydrocarbon-degrading microorganisms, nutrients and surfactants. What information will you need to decide on the best approach?

Name four factors that affect the death rate and effectiveness of any microbial agent.

Explain the difference in Microbial Inhibitory Concentration and Microbial Bactericidal Concentration.  (When explaining differences you have to talk about both things being compared.  Just explain how they are different.  Definitions will not be accepted.)

If an antimicrobial drug does not exhibit selective toxicity, what might be a problem experienced by the patient?  The host cells will be damaged. The pathogen will be the only microbe killed. The normal microbiota will grow too much. The host will recover without experiencing any drug side effects.

The survival, growth and reproduction of microorganisms are influenced by physical and nutritional factors in its environment. Give the principle of microbial destruction/microbe population control behind sunbathing sleeping mats and pillows

Broad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment choice?   Broad-spectrum antimicrobials are usually toxic to the host cells. Broad-spectrum antimicrobials only work if they are used shortly after the infection begins. Broad-spectrum antimicrobials may kill much of the normal microbiota. Broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth. Broad-spectrum antimicrobials may stimulate excess growth of the normal microbiota.

Discuss biofilms and their relevance to infectious diseases. Discuss population growth and the phases of a typical bacterial growth curve. Describe generation time for a bacterial population Explain how bacterial growth correlates to disease. Describe how environmental changes can alter the shape of a growth curve. Categorize microbes based on their preferred environmental niches (pH, temperature, oxygen and salt). Identify the biological properties that allow different classes of microbes to grow in extreme environments.

Why is biofilm development in catheters (tubes that can be inserted into a body cavity, duct or vessel which allow drainage or injection of fluids) such a dangerous source of infection in hospitals?

based on the article What happens to the microbial environment as cheeses like Gouda, Cheddar, or Parmesan are aged? I need help finding the answer in the article

Why does saliva not serve as a good microbialgrowth medium?
