Abstract:

The composition of fatty acids in triacylglycerides (TAGs) and their position on the glycerol backbonehigh-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) were used to analyze the compositionand distribution of fatty acids in TAGs of different rapeseed oils.Our results show the content of oleic acid in high-oleic-acid rapeseed oil to be about 80%.In high-erucic-acid rapeseed oil, however, oleic acid was enriched at the sn-1/3.

Effects of fatty acid chain length and degree of unsaturation on the surface activities of monoacyl trehaloses

Yue-E SUN, Wenshui XIA, Xueyan TANG, Zhiyong HE, Jie CHEN,

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 4,   Pages 407-412 doi: 10.1007/s11705-009-0255-9

Abstract: The surface properties of monoacyl trehaloses with different acyl chains were investigated at 30°C, 40°C, 50°C, and 60°C. Monoacyl trehaloses were enzymatically synthesized and purified with silica gel column chromatography and semi-preparative high-performance liquid chromatography (HPLC), and the purity of products was identified by mass spectrometry (MS) and nuclear magnetic resonance (NMR). The surface tension of monoacyl trehalose in pure water was measured using Doüy ring method at different temperatures. The critical micelle concentrations (CMC), surface tension at the CMC, , and residual area per molecule, , were estimated from the curves. The CMC value of unsaturated monoacyl trehalose was affected by both the degree of unsaturation and the acyl chain length, and the effect of chain length on the CMC value was much stronger than that of the unsaturation degree. However, there was no significant dependency of the value and a values on the chain length or the unsaturated degree.

Microalgae

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 784-791 doi: 10.1007/s11783-013-0590-4

Abstract: Renewable algae biomass, was used as substrate for generating electricity in two chamber microbial fuel cells (MFCs). From polarization test, maximum power density with pretreated algal biomass was 102 mW·m (951 mW·m ) at current generation of 276 mA·m . The individual electrode potential as a function of current generation suggested that anodic oxidation process of algae substrate had limitation for high current generation in MFC. Total chemical oxygen demand (TCOD) reduction of 74% was obtained when initial TCOD concentration was 534 mg·L for 150 h of operation. The main organic compounds of algae oriented biomass were lactate and acetate, which were mainly used for electricity generation. Other by-products such as propionate and butyrate were formed at a negligible amount. Electrochemical Impedance Spectroscopy (EIS) analysis pinpointed the charge transfer resistance (112 ?) of anode electrode, and the exchange current density of anode electrode was 1214 nA·cm .

Improved energy recovery from dark fermented cane molasses using microbial fuel cells

Soumya Pandit, Balachandar G, Debabrata Das

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 1,   Pages 43-54 doi: 10.1007/s11705-014-1403-4

Abstract: A major limitation associated with fermentative hydrogen production is the low substrate conversion efficiency. This limitation can be overcome by integrating the process with a microbial fuel cell (MFC) which converts the residual energy of the substrate to electricity. Studies were carried out to check the feasibility of this integration. Biohydrogen was produced from the fermentation of cane molasses in both batch and continuous modes. A maximum yield of about 8.23 mol H /kg COD was observed in the batch process compared to 11.6 mol H /kg COD in the continuous process. The spent fermentation media was then used as a substrate in an MFC for electricity generation. The MFC parameters such as the initial anolyte pH, the substrate concentration and the effect of pre-treatment were studied and optimized to maximize coulombic efficiency. Reductions in COD and total carbohydrates were about 85% and 88% respectively. A power output of 3.02 W/m was obtained with an anolyte pH of 7.5 using alkali pre-treated spent media. The results show that integrating a MFC with dark fermentation is a promising way to utilize the substrate energy.
