10. Dynamics of Microbial Growth

Methanopyrus kandleri is a species of archaea that lives in the hydrothermal vents of the Pacific Ocean. This species' optimal temperatures are between 100-122 ºC. This species also does not require oxygen, as it survives off of hydrogen gas and releases methane gas. What environmental classifications would this archaeal species fit into?

Acidobacterium capsulatum is a species of bacteria that grows better in the absence of oxygen but can survive if oxygen is present. This species of bacteria also thrives in soil and water with a pH between 3.0 and 6.0. What environmental classifications would this bacterial species fit into?

NAME IT A prokaryotic cell hitched a ride to Earth on a space shuttle from some unknown planet. The organism is a psychrophile, an obligate halophile, and an obligate aerobe. Based on the characteristics of the microbe, describe the planet.

Differentiate cellular and plasmodial slime molds. How does each survive adverse environmental conditions?

Acetobacter is necessary for only one of the steps of vitamin C manufacture. The easiest way to accomplish this step would be to

a. add substrate and Acetobacter to a test tube.

b. affix Acetobacter to a surface and run substrate over it.

c. add substrate and Acetobacter to a bioreactor.

d. find an alternative to this step.

e. none of the above

Barophiles _______.

a. Cannot cause diseases in humans

b. Live at normal barometric pressure

c. Die if put under high pressure

d. Thrive in warm air
