others. Two examples of selective medium are Mannitol Salt agar and Phenylethyl Alcohol. 2. What is a differential medium? What makes the medium differential? Name 2 examples (3 pts.) Differential medium is distinguishing microorganisms from one another based on growth characteristics. A medium is differential when you are able to visibly see the differences in growth patterns of organisms. Differential media include blood agar and Eosin Methylene Blue.

1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of

inoculate a Tryptic Soy Broth (TSB) plate with a sample from the environment. TSB is rich in nutrients and can support the growth of a number of bacteria or fungi; therefore you will be able to isolate microorganisms from your hands or other parts of the body or from the oral cavity‚ from your benchtop or from other inanimate objects. With a wax pen label the bottom of a Petri plate containing TSB-agar with your name‚ date‚ lab section‚ and source of the inoculum. It is

Because of the presence of peritrichous flagella‚ species included this genus are motile and most strains swarm in periodic cycles‚ producing a characteristic concentric swarming pattern‚ or spread in a uniform film over nutrient media solidified with agar or gelatin‚ which is evident in the streak plates done over the course of a few weeks‚ the streak plates showing the

group’s hypothesis was that “cells are small because small cells have a larger surface area to volume ratio”‚ which is important because a larger surface area allows for more molecules to diffuse at one time. The group created cells made out of blocks of agar-phenolphthalein. This allowed a simple indicator of pH‚ since phenolphthalein turns magenta when it comes into contact with a base.
