Impact of Salt stress on growth and lipid content in oleaginous green microalgae

Abstract

At present time, about 70% of energy is generated from fossil fuels and only about 30% is produced from renewable energy sources. The forecasted energy demand increases make evident that the conventional oil reserves that can be commercially exploited was vanished after 2050. Deteriorating Environmental condition demands sustainable renewable energy sources with least greenhouse gases emission. Third generation biofuel from microalgae can fulfill are demand of environmentally friendly biofuel with least GHG emission. In present research an affected has been made to enhance lipid content via saline stress. Lipid estimate showed a significant source in lipid. It may help to curb are dependency on fossil fuels. Fossil fuels are high energy sources, but these are Reduce day to day. These fuels high demand present in time but fossil stock is limited. The present work is a particularly important and unique work to cope with fossil fuel deficiency and greenhouse gases (GHGs). Oleaginous green microalgae are very efficient to overcome fossil fuel deficiency and environment related problem. In this work we will cultivate in-vitro three different microalgae which have significant amount of lipid. And second phase saline stress was employed to enhance lipid content in the selected microalgae.
