Sorting cells of the microalga Chlorococcum littorale with increased triacylglycerol productivity
BACKGROUND Despite extensive research in the last decades, microalgae are still only economically feasible for high valued markets. Strain improvement is a strategy to increase productivities, hence reducing costs. In this work, we focus on microalgae selection: taking advantage of the natural biological variability of species to select variations based on desired characteristics. We focused on...
متن کاملEffects of light intensity and temperature on photoautotrophic growth of a green microalga, Chlorococcum littorale
A highly CO2-tolerant green alga, Chlorococcum littorale, was investigated at temperatures ranging from 8 to 28 °C, light intensities from 30 to 170 μmol m-2 s-1, a constant CO2 concentration of 5% (v/v) and atmospheric pressure. The experimental results showed that a specific growth rate μ, defined in terms of cell growth rate under a logarithmic growth phase, increased with temperature up to ...
متن کاملEffects of gas compositions on the productivity of biomass and intra-cellular fatty acids in a green alga Chlorococcum littorale under the photoautotrophic conditions
The effects of gas composition on the productivity of biomass and intra-cellular fatty acids were investigated in semi-batch cultures of a green alga Chlorococcum littorale (C. littorale) with gas flowing at 100 ml/min under the conditions of temperature of 22 C and light intensity of 4200 lx. Growth rates were enhanced and total fatty acids contents increased by flowing an O2-free gas mixture ...
متن کاملPrevious Repeated Exposure to Food Limitation Enables Rats to Spare Lipid Stores during Prolonged Starvation.
The risk of food limitation and, ultimately, starvation dates back to the dawn of heterotrophy in animals, yet starvation remains a major factor in the regulation of modern animal populations. Researchers studying starvation more than a century ago suggested that animals subjected to sublethal periods of food limitation are somehow more tolerant of subsequent starvation events. This possibility...
متن کاملRadiation characteristics of Botryococcus braunii, Chlorococcum littorale, and Chlorella sp. used for CO2 fixation and biofuel production
This paper reports experimental measurements of the radiation characteristics of green algae used for carbon dioxide fixation via photosynthesis. The generated biomass can be used to produce not only biofuels but also feed for animal and food supplements for human consumptions. Particular attention was paid to three widely used species namely Botryococcus braunii, Chlorella sp., and Chlorococcu...
