Many green microalgae significantly increased their cellular
neutral lipid
content when cultured in
nitrogen
limited or
high light
conditions. Due to their lipid production potential, these algae have been suggested as promising feedstocks for biofuel production. However, no models for algal lipid synthesis with respect to nutrient and light have been developed to predict lipid production and to help improve the production process. A
mathematical model
is derived describing the growth dynamics and
neutral lipid
production of green microalgae grown in batch cultures. The model assumed that as the
nitrogen
was depleted, photosynthesis became uncoupled from growth, resulting in the synthesis and accumulation of neutral lipids. Simulation results were compared with
experimental data
for the green microalgae Pseudochlorococcum sp. For growth media with low
nitrogen
concentration, the model agreed closely with the data; however, with high
nitrogen
concentration the model overestimated the biomass. It is likely that additional limiting factors besides
nitrogen
could be responsible for this discrepancy.
