Question

Seven metabolically different microorgansisms are described below (A-G). Six media also are given and the condition of the incubation. For each medium list the organisms that could grow under the conditions specified and for each organism give its carbon source, energy source, nitrogen source, electron donor, and electron acceptor.

A.      Chemo-organotrophic, fermentative metabolism, no cytochromes, no catalase, requires organic N, has multiple organic growth factor requirement

B.      Photolithotrophic, autotrophic, uses bacterial (type II) photosynthesis (H2O is not the source of electrons)

C.      Photo-organotrophic, facultative phototroph, facultative anaerobe, prototrophic, has bacterial type of photosynthesis

D.      Photolithotrophic, autotrophic, has plant type (type I, uses H2O as source of electrons)

E.       Chemoorganotrophic, respiratory metabolism, aerobic or anaerobic, prototrophic

F.       Chemolithotrophic, prototrophic

G.      Chemoorganotrophic, respiratory or fermentative metabolism, has multiple growth factor requirements

1.       Glucose, Tryptone, Yeast extract all at one gram in 1 L of H20 in the dark and open to the air

2.       Glucose at 1 gm, Potassium-di-hydrogen-phosphate at 0.1 gm, di-ammonium-sulfate at .1 gm, sodium nitrate at .1 gm, all in one liter of H2O in the light but closed to air

3.       di-ammonium-sulfate at .01 gm, Potassium-di-hydrogen-phosphate at 0.1 gm, sodium bi carbonate at .1 gm, sodium nitrate at .1 gm all in 1 L of H2O in the light, with no air present

4.       Glucose, Tryptone, at 1.0 gram and Yeast extract 0.1 gram, ammonium chloride at .1 gm in 1 L of H20 in the dark and without air

5.       Sodium bicarbonate and sodium sulfide at 1 gm, di-potassium-hydrogen-phosphate, ammonium chloride at 0.1 gm, all in 1 L of H2O in the light and not open to the atmosphere (no air).

6.       di-ammonium-sulfate at 1 gm, di-potassium-hydrogen-phosphate at 1 gm, all in 1 L of H2O in the light, open to the atmosphere (with air).

A.      Chemo-organotrophic, fermentative metabolism, no cytochromes, no catalase, requires organic N, has multiple organic growth factor requirement

B.      Photolithotrophic, autotrophic, uses bacterial (type II) photosynthesis (H2O is not the source of electrons)

C.      Photo-organotrophic, facultative phototroph, facultative anaerobe, prototrophic, has bacterial type of photosynthesis

D.      Photolithotrophic, autotrophic, has plant type (type I, uses H2O as source of electrons)

E.       Chemoorganotrophic, respiratory metabolism, aerobic or anaerobic, prototrophic

F.       Chemolithotrophic, prototrophic

G.      Chemoorganotrophic, respiratory or fermentative metabolism, has multiple growth factor requirements
