Question

A novel microbe that can perform both steps of nitrification. It mentions that the unique gene sequences identified from this microbe have now been found in a variety of environments. These include natural systems, soil, groundwater, and engineered systems. What can we conclude from the discovery of these gene sequences?

A. Wastewater treatment plans that use treatments to inhibit ammonia-oxidizing Bacteria and ammonia-oxidizing Archaea can use the same treatments to control comammox bacteria. B. The newly discovered species is abundant in a wide range of habitats, as these gene sequences are not present in any other species. C. There may be a variety of microbes that contain these genes. D. Comammox microbes may play a significant role in nitrification in both nature and in human environments.

Explanation / Answer

The newly discovered species is abundant in a wide range of habitats, as these gene sequences are not present in any other species - Since, the gene sequence is unique to this Comammox microbe, it can be inferred that they are present in wide range of habitats. Comammox microbes may play a significant role in nitrification in both nature and in human environments - Since, they can convert ammonia into nitrite and then into nitrate individually, they will play a significant role in the environment because, usually bacteria either convert ammonia to nitite or nitrite to nitrate and absence of one species of bacteria will affect the nitrogen cycle.
