Excretion of glycerol by the marine Chlamydomonas sp. strain W-80 in high CO2 cultures

Potential for green microalgae to produce hydrogen, pharmaceuticals and other high value products in a combined process

“…In some cases, the algae can also excrete glycerol as a response to high CO 2 rather than salt stress, as has been observed in a marine Chlamydomonas sp. strain (Miyasaka et al , 1998). Glycerol is widely used in industries such as cosmetics, pharmaceuticals, paint, automotive, food (E422), tobacco, pulp and paper, leather, and textile, or as a feedstock for the production of various chemicals (Wang et al , 2001).…”

BioCO2 – A multidisciplinary, biological approach using solar energy to capture CO2 while producing H2 and high value products

“…Exposure to high CO 2 concentrations have shown to increase the production of high value biomolecules (Miyasaka et al, 1998), see modules 4 and 5. Considerable effort has been invested in constructing bioreactors for the purpose of efficient CO 2 fixation into algal biomass (Cheng et al, 2006;Keffer and Kleinheinz, 2002;Ono and Cuello, 2004;Pulz, 2001;Sato et al, 2006;Usui and Ikenouchi, 1997).…”

“…Among the most commercially successful products from microalgae are astaxanthine and other carotenoids used as an antioxidant and coloring agent in food industry and aquaculture (Algatechnologies Ltd.; BioReal AB; Cyanotech Corp.; Mera Pharmaceuticals Inc.). Other products include fatty acids for use in lipid based cosmetics like creams and lotions, poly-bhydroxybutyrate for production of plastics, polysaccharides like agar, alginates, carrageenans and other thickening agents (De Philippis et al, 2001;Ramesh and Tharanathan, 2003), antioxidants for preservation of cosmetics and sun protection, glycerol widely used in food industry and for personal care products (Miyasaka et al, 1998), various pigments for coloring of fish muscles, chicken skin, egg yolks and cosmetics.…”

ZIF-8 : novel catalytic material for the conversion of CO2 to cyclic carbonates.

“…The utilization of algae/microalgae in the conversion of CO 2 to biomass was studied abundantly. [21][22][23][24][25][26] Algae can be thought of as marine and freshwater plants that have higher photosynthetic efficiencies than terrestrial plants and are more efficient capturing carbon. 21 It is found that high CO 2 concentrations promote the growth speed of some strains of green algae capable of growing rapidly under [23][24][25] and increase the production of high value biomolecules.…”

“…21 It is found that high CO 2 concentrations promote the growth speed of some strains of green algae capable of growing rapidly under [23][24][25] and increase the production of high value biomolecules. 26 It is important to select a train of algae with a high CO 2 fixing rate, a rapid growth rate and easy cultivation on a large scale in order to generate a large biomass yield. 27 The produced biomass can subsequently be converted into biofuels, bio-chemicals, food or animal feed.…”
