Algae are potential feedstocks that can be used for the production of biofuels and thus providing solution for the challenges of energy crisis and environmental greenhouse gasses. Several companies and government agencies are funding efforts to reduce capital and operating costs and make algae fuel production commercially viable.Harvested algae, like fossil fuel, releases CO2 when burnt but unlike fossil fuel the CO2 is taken out of the atmosphere by the growing of algae and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels, using land that is not suitable for agriculture.The present study was aimed to collect algal samples from various localities in Lahore, identification, optimization of culture conditions and comparison of oil production of different algal species.

This work was carried out with the objective to find out a solution to cope with the problem of soil salinity; a major constraint to crop production. This work is of great importance in explaining new ways to improve salt tolerance of sugarcane. We are optimistic that this can be also useful for other plants as well. The work not only describes the improvement of salinity tolerance but also throws light on the relationship of salinity tolerance with antioxidant enzyme activities. To conclude we would like to say that it is only a minute cintribution to the vast sea of knowledge having a lot of hard work and originality behind it.
