When culturing a chemoorganoheterophic bacterium, what outcome is LEAST likely to occur if ammonia and phosphate are provided at equal concentrations?
A. Cells require much less P to grow than N, so extra P will be used for ATP synthesis and result in a faster growth rate.
B. Cells will never consume all of the phosphate, because N is needed in higher quantities than P.
C. The final biomass of cells will be no different than if only 50% of the phosphate was provided.
D. The bacteria will import all of the ammonia to use for biosynthetic pathways.
