Across

  1. A medium that contains additives that enhance the growth of certain organisms.
  2. The ocular lens of a microscope. (2 words)
  3. One-one millionth (1/ 1,000,000) of a meter.
  4. This spectrophotometer reading is directly proportional to the cell concentration. (The greater the reading, the greater the number of bacteria.)
  5. Bacteria that grow best at moderate temperatures. Their optimum growth temperature is between 25°C and 45°C.
  6. Organism that grow only in the presence of oxygen. (2 words)
  7. A chain of cocci.
  8. Organism that require a low concentration of oxygen for growth.
  9. A visible mass of microorganisms growing on an agar surface and usually originating from a single organism or arrangement of organisms.
  10. Pigment diffuses out of the organism into the surrounding medium. Both the colonies and the agar will appear pigmented. (2 words)
  11. A mass of organisms is floating on top of the broth.
  12. An incomplete spiral or comma-shaped bacterium.
  13. Able to produce pigment during growth.
  14. Free of all life forms.
  15. Cold-loving bacteria. Their optimum growth temperature is between -5°C and 15°C.
  16. Organism that grow only without oxygen and, in fact, oxygen inhibits or kill it. (2 words)
  17. The first of an organism's scientific names.
  18. One-one billionth (1/ 1,000,000,000) of a meter.
  19. A thick, rigid spiral.
  20. A cylindrical or hotdog-shaped bacterium.

Down

  1. The organisms appear as a general cloudiness throughout the broth.
  2. A medium that contains additives that cause an observable color change in the medium when a particular chemical reaction occurs.
  3. Determining the number of bacteria in a certain volume of a sample by counting the number of colonies that grow from that sample. (2 words)
  4. A medium that has agents added that will inhibit the growth of one group of organisms while permitting the growth of another.
  5. Bacteria that grow at very high temperatures. Their optimum growth temperature is between 70°C and 110°C.
  6. The solidifying agent added to culture medium in order to grow bacteria on a solid surface.
  7. A mass of organisms appears as a deposit at the bottom of the tube.
  8. The second of an organism's scientific names.
  9. Cocci in irregular, often grape-like clusters.
  10. Organism that grow with or without oxygen, but generally better with oxygen. (2 words)
  11. A microbial culture in which all organisms are descendants of the same organism. (2 words)
  12. A medium that is selective for Gram-negative bacteria and differentiates bacteria based on lactose fermentation.
  13. Pigment does not diffuse out of the organism into the surrounding medium. The colonies appear pigmented but the agar does not change color. (2 words)
  14. A liquid medium.
  15. Heat-loving bacteria. Their optimum growth temperature is between 45°C and 70°C.
  16. A thin, flexible spiral .
  17. A cube of eight cocci.
