Enhanced lipid productivity approaches in microalgae as an alternate for fossil fuels – A review

Abstract: Renewable energy sources especially biofuel is the focus in energy field. Microalgae have rapid biomass production and high oil content which is a promising oil producing alternative for fossil fuels and oil based crops. Changes in algal lipid production and composition have been attributed to variations in environmental and culture conditions. Stressful environmental conditions change the use of carbon uptake by algae for proliferation to energy storage in the form of oil. Fatty acids and triacylglycerols are energy storage compounds in microalgae accumulated under nutrient deprivation and stress conditions. The balance between maximum biomass and lipid production against the culturing conditions will be the ultimate goal of biofuel production from algae. Identification of suitable approaches for triggering algal lipid biosynthesis and lipid accumulation opens the door for enhanced lipid production with absolute quality and quantity of algae based fuels. This review lays the foundation for lipid induction strategies in microalgae to accelerate the application of algal biofuels as an alternate of fossil fuels for sustainable environment. Of the various approaches discussed, the one most often considered is that of nutrient limitation. Given the limitations of nutrient influenced lipid production, identifying other feasible approaches like CO 2 influence, temperature, salinity and heavy metal stress will reduce the negative impacts of existing approaches thereby to obtain maximum microalgal lipid production.

Insight into thermophiles and their wide-spectrum applications

Abstract: The deconstruction of biomass is a pivotal process for the manufacture of target products using microbial cells and their enzymes. But the enzymes that possess a significant role in the breakdown of biomass remain relatively unexplored. Thermophilic microorganisms are of special interest as a source of novel thermostable enzymes. Many thermophilic microorganisms possess properties suitable for biotechnological and commercial use. There is, indeed, a considerable demand for a new generation of stable enzymes that are able to withstand severe conditions in industrial processes by replacing or supplementing traditional chemical processes. This manuscript reviews the pertinent role of thermophilic microorganisms as a source for production of thermostable enzymes, factors afftecting them, recent patents on thermophiles and moreso their wide spectrum applications for commercial and biotechnological use.
