- An organism is discovered living near hydrothermal vents deep in the ocean where sunlight cannot reach. It is found to gain energy through the oxidation of inorganic sulfur compounds present in its environment and uses this energy to turn CO2 into complex organic compounds. Based on this information, how would this organism be best categorized metabolically? Chemoautotroph Chemoheterotroph Photoautotroph PhotoheterotrophThe ingredients in the MR/VP Broth are: Peptone (protein) 7g Glucose 5g Phosphate buffer 5g Distilled water 1L Examine the above figure. This figure shows how the pH in the Methyl Red and Voges-Proskauer (MR-VP) broth changes during incubation from time zero to 48 hours with a VP-positive bacteria species. VP-positive bacteria initially produce lactic acid and temporarily lower the pH, but the lowered pH activates the 2,3-butanediol fermentation pathway. Accumulation of its neutral end products such as acetoin and 2,3-butanediol raises the pH by the end of the incubation time. The acetoin that accumulates in the broth also reacts with the reagents added after incubation to produce a red color. If the reagents were added and the results were recorded early, at 24 hours rather than at the full incubation time at 48 hours, would the color result for the VP (+) bacteria be the same at 24 hours than at 48 hours? If different, explain how the color result is different.
