A Priority

There are a lot of research programs focusing on the development of new solvents for carbon dioxide capture. The most important priority should be reducing the energy consumption needed at the regeneration step, but minimizing solvent degradation and its corrosivity is also considered as a priority. In this research, the aqueous blends of 2-amino-2-methyl-1-propanol (AMP: 1 kmol·m−3) and 1-amino-2-propanol (MIPA: 0.1–0.5 kmol·m−3) are characterized in terms of density, viscosity, and surface tension. The carbon dioxide absorption rate and capacity, the regeneration capacity, and the corrosivity of these solvents are also evaluated.

Microbial Origin

The biosurfactants from microbial origin increasingly gained interests because of their application in many field and excellent properties compared to surfactants from chemical origin, such as the higher biodegradability, lower toxicity and environmentally friendly. Sophorolipids, biosurfactants of glycolipid groups are produced through the fermentation by nonpathogenic yeasts such as Candida bombicola. In this study, we investigated the production, surveyed properties of sophorolipids through fermentation by C. bombicola from coconut oil. The results showed that the yield of sophorolipid obtained after 7 days of culture was 14.6 g/L, the surface tension was 40 mN/m. The obtained sophorolipid showed ability to be resistant to some bacteria such as E. coli, B. subtilis, P. aeruginosa, and S. aureus. Through DPPH experiment, sophorolipids showed the scavenging acitivity with IC50 = 1.4063 mg/mL. These results showed that sophorolipids could be applied in cosmetics.
