Prochlorophyte bacteria are photosynthesizers and have the same chlorophyll found in algae and vegetables, studies claim that these bacteria are the most abundant beings on the planet, accounting for half of all photosynthesis performed in the oceans.
Prochlorophyte bacteria can be divided into <em>Prochloron</em>, <em>Prochlotrix</em> and <em>Prochlorococcus</em> genera.
However, <u>prochlorobacteria</u> are not responsible for the production of dairy products, in which the most associated bacterial genera are <em>Lactobacillus</em> and <em>Streptococcus</em>. This last statement implies that alternative b is the correct one.
