Effect of plant hormones on the production of biomass and lipid extraction for biodiesel production from microalgae chlorella sp.

renewable without causing adverse effects to the life forms. Microalgae are currently considered to be one of the most promising
alternative sources for biodiesel and the application of phytohormones has also been considered a promising way to increase the
production of lipid from microalgae recently. The present study is aimed to cultivate the algal species, Chlorella as a feedstock and the
effect of various concentrations of phytohormones such as 6-Benzylaminopurine (BAP), Gamborg’s b-5 vitamins, Indole-3-butyric acid
(IBA), 2, 4-Dichlorophenoxyacetic acid (2,4-D) was used for the production of lipid. The extracted lipid oils were then converted into
methyl ester via the transesterification process. Indole-3-butyric acid (IBA) relatively supported the maximum growth of 7.185 g/ ml
and the lipid yield was 3.5g/ml. The GC-MS characterization showed many peaks corresponding to the fatty acid methyl esters. Among
those Ethylbenzene, o-Xylene, Benzene,1,2,4-trimethyl and Decane peaks of hydrocarbons were found important in the biofuel
production. The current study demonstrates that the phytohormone IBA accelerate the microalgae growth and also induce the production
of lipid oils for biodiesel production.
