Abstract
An economically feasible and sustainable microalgal biorefinery needs to develop culture stra tegies to maximize biomass productivity and accumulate important metabolites in select micro algae. The present study evaluated the effect of indole-3-acetic acid (IAA) and diethyl amino ethyl hexanoate (DAH) on two marine microalgae of commercial importance, viz., Porphyridium pur pureum and Dunaliella salina. The photosynthetic efficiency, biomass productivity, and accumu lation of PUFA rich lipids in P. purpureum and D. salina were studied. The microalgal cultures supplemented with both the phytohormones at lower concentrations (10-7 to 10-8M) showed an enhanced biomass production (2 to 3.5 fold increase), lipid content (up to 1.4 fold increase), and PUFA content (1 to 2 fold enhancement) at p < 0.001, compared to control cultures. The maximum photosynthetic efficiency (Fv/Fm) of IAA and DAH supplemented microalgal cultures increased up to 2.2 fold with up to a two-fold reduction in the average antenna size (ABS/RC) and dissipation energy (DI0/RC). The study suggests that supplementing the P. purpureum and D. salina cultures with phytohormone could effectively enhance the biomass production and accumulation of PUFA rich lipids.
