Oil-accumulating microalgae have the potential to enable large-scale biodiesel production without competing for arable land or biodiverse natural landscapes. High lipid productivity of dominant, fast-growing algae is a major prerequisite for commercial production of microalgal oil-derived biodiesel. However, under optimal growth conditions, large amounts of(More)
Omega-3 fatty acids, such as eicosapentaenoic acid (EPA), provide substantial health benefits. As global fish stocks are declining and in some cases are contaminated with heavy metals, there is a need to find more sustainable land-based sources of these essential fatty acids. The oleaginous microalga Nannochloropsis sp. has been identified as a highly(More)
In the wake of intensive fossil fuel usage and CO2 accumulation in the environment, research is targeted toward sustainable alternate bioenergy that can suffice the growing need for fuel and also that leaves a minimal carbon footprint. Oil production from microalgae can potentially be carried out more efficiently, leaving a smaller footprint and without(More)
Rapid induction of lipid accumulation in microalgae is an important prerequisite towards the use of microalgae as a feedstock for biodiesel production. In this study, we present a novel approach to induce lipids in Chlorella sp. within 24 h by short-term UV-C radiation (UVR) stress at different energy intensities ranging from 0 to 1000 mJ/cm2. Increase in(More)
Microalgae are primary producers of organic pigments carotenoids in aquatic environments. However, commercial-scale microalgae application for high value carotenoids production is rarely economical due to the cost-effectiveness of carotenoid induction and microalgal harvesting process. Here, we present a novel approach, using a small dose of externally(More)
Mutagenesis and selection of microalgae can be used for accelerated breeding of elite strains, providing a significant advantage over genetic engineering as prior biochemical and genetic information is not required. Ultraviolet (UV)-C-induced mutagenesis combined with fluorescence-activated cell sorting (FACS) and microtiter plate reader cell density(More)
