What part of innate immunity best combats bacterial sidephores?

What does media need to include? What techniques can scientists use to count the number of bacteria in a culture?

What is happening at the different stages of the growth curve? How could you experimentally test if a culture is in the death phase?

Please compare and contrast continuous culture with synchronous culture.

How does Caulobacter crescentus sequentially turn on groups of genes needed for cell cycle progression?

What are biofilms and what is their signficance?

Please describe the process of sporulation and germination.

How can we describe microorganisms that grow at different temperatures?

Please demonstrate how exponential growth of a microbial culture and exponential death in response to antimicrobial agent both are logarithmic. This is a math-based equation.
