Treating wastewater requires the removal of organic material, and an ideal phenotype of a bacterium to do this would flocculate to make the cells settle (rather than staying in suspension) in a wastewater stream. Which species would be best for this application?

A) Bartonella quintanaB) Burkholderia cepaciaC) Wolbachia pipientisD) Zoogloea ramigera

Zoogloea ramigera

Explanation:

Zoogloea ramigera is a type of aerobic gram-negative bacteria. This bacteria is most commonly found in aquatic environments such as sludges that are highly enriched. Zoogloea ramigera is characterized by its ability to form flocs as well as films in the liquid media during different stages of its growth. Due to the ability of Zoogloea ramigera to form sludge deposits and flourish when the biological oxygen demand is low, it is actively used for wastewater management. Zoogloea ramigera can form activated flocs in the sludge and these flocs then settle down at the bottom of the treatment tank and thus, the bacteria contribute to the purification process.
