To elaborate further we developed a futuristic scenario where in
addition of other data given in Table 1, biomass concentration was
increased to 6 g/L when hydrolyzate was used for algal biomass
production. 40% lipid content was assumed to be achieved for algae
that are grown using AD effluent and hydrolyzate. Using the above
mentioned data the overall bioenergy production in the 3rd scenario
could be increased as compared to 2nd scenario (Fig. 2). In
the futuristic case, where optimistic data were used for modeling
(Fig. 2) even in the 1st scenario, overall bioenergy production
was found to be higher than that in 2nd scenario (realistic case).
This study therefore, elaborates that technological breakthrough
in the form of enhanced productivity and lipid production has
immense potential to cut down the energy consumption and
GHG emission from the algal biofuel production.
