Which nitrogen source do you prefer: Chlorella protothecoides growth in ammonia and urea

Abstract

Algae is now being considered as a source for biofuels, which could eventually become a replacement for the fossil fuels we use today. Algal biomass can be used to produce biofuels. We tested the affect of ammonia and urea on algal growth, predicting that urea will produce more algal growth than ammonia because it is an organic compound. We doubled the moles of nitrogen in the growth medium by adding the calculated amount of ammonia and urea. We can not state whether or not our hypothesis was supported because we have not collected all of our data yet, but we can say that nitrogen does increase algal growth like previously shown.
