Abstract
Microalgae are the most sought after sources for biofuel production due to their capacity to utilize carbon and synthesize it into high density liquid. Current energy crisis have put microalgae under scanner for economical production of biodiesel. Modifications like physiological stress and genetic variation is done to increase the lipid yield of the microalgae. A study was conducted using a microalgal consortium for a period of 15 days to evaluate the feasibility of algal biomass from laboratory as well as outdoor culture conditions. Native algal strains were isolated from a tropical freshwater lake. Preliminary growth studies indicated the relationship between the nitrates and phosphates to the community structure through the days. The lipid profile done using Gas chromatography – Mass spectrometry, revealed the profile of the algal community. Resource competition led to isolation of algae, aided in the lipid profile of a single alga. However, further studies on the application of the mixed population are required to make this consortium approach economically viable for producing algae biofuels.

Microalgae are found in both marine and freshwater proportional to the stimulus received from the ecosystems
USA)], provided impetus to the global biofuel research. production of microalgal biomass can be achieved by two Important advances in microalgal strain are isolation and methods, conventional open pond system and closed characterization, physiology and biochemistry, genetic photo bioreactors

Summary
Microalgae are found in both marine and freshwater proportional to the stimulus received from the ecosystems. Large scale cultivation of microalgae algae gathered from various sites and they were in open pond systems relies on natural light for screened for their tolerance to environmental conditions illumination. Closed photobioreactor: These are preferred over alternative, in the context of food security and open ponds as they can be established and maintained requirement of large stocks to meet the growing fuel either indoor or outdoor (Pulz, 2001) The objectives of the study were: 1) to check the role of environmental parameters on the growth of the consortium in outdoor as well as indoor culture conditions; 2) lipid characterization of the consortium to understand the efficiency for biofuel production. The light intensity of 1320 lx was provided using Compact fluorescent lamps (Philips Genie, Made in India) with 16:8 hours light and dark phase respectively
