1.Expression and characterization of a novel 1,3-regioselective cold-adapted lipase from Rhizomucor endophyticus suitable for biodiesel synthesis.
Yan Q1, Duan X2, Liu Y2, Jiang Z2, Yang S2. Biotechnol Biofuels. 2016 Apr 14;9:86. doi: 10.1186/s13068-016-0501-6. eCollection 2016.
BACKGROUND: The biodiesel production can be carried out by transesterification using either chemical or enzymatic process. The enzymatic transesterification is more promising as it offers an environmental friendly option compared to the chemical process, where the lipases with high catalytic efficiency and good stability play a key role. Hence, it is of great value to identify novel lipases which are suitable for biodiesel production.

The new dinuclear ZnII-DyIII and trinuclear ZnII-DyIII-ZnII complexes of formula [(LZnBrDy(ovan) (NO3)(H2O)](H2O)·0.5(MeOH) (1) and [(L1ZnBr)2Dy(MeOH)2](ClO4) (3) (L and L1 are the dideprotonated forms of the N,N'-2,2-dimethylpropylenedi(3-methoxysalicylideneiminato and 2-{(E)-[(3-{[(2E,3E)-3-(hydroxyimino)butan-2-ylidene ]amino}-2,2-dimethylpropyl)imino]methyl}-6-methoxyphenol Schiff base compartmental ligands, respectively) have been prepared and magnetostructurally characterized. The X-ray structure of 1 indicates that the DyIII ion exhibits a DyO9 coordination sphere, which is made from four O atoms coming from the compartmental ligand (two methoxy terminal groups and two phenoxido bridging groups connecting ZnII and DyIII ions), other four atoms belonging to the chelating nitrato and ovanillin ligands, and the last one coming to the coordinated water molecule. The structure of 3 shows the central DyIII ion surrounded by two L1Zn units, so that the DyIII and ZnII ions are linked by phenoxido/oximato bridging groups.
3.Simultaneous analysis of eight vitamin E isomers in Moringa oleifera Lam. leaves by ultra performance convergence chromatography.
Qi N1, Gong X2, Feng C3, Wang X4, Xu Y5, Lin L6. Food Chem. 2016 Sep 15;207:157-61. doi: 10.1016/j.foodchem.2016.03.089. Epub 2016 Mar 30.
A new method for simultaneous determination of eight vitamin E isomers including α-, β-, γ-, and δ-tocopherol and α-, β-, γ-, and δ-tocotrienol by ultra-performance convergence chromatography (UPC(2)) equipped with a diode array detector was reported. They were separated on a BEH 2-EP column (3.0mm×100mm, 1.7μm) using gradient elution (95:5-80:20) with a mobile phase consisted of CO2 and methanol:isopropanol (1:1, v/v), back pressure of 1800psi, flow rate of 1.5ml/min and detection at 294nm. The results showed good linearity (R(2)=0.9990-0.9998) and high resolution (1.48-7.67). Limits of detection (LOD) and quantification (LOQ) ranged from 23-49ng/L and 70-150ng/L, respectively. Relative standard deviations (RSD) for repeatability and reproducibility were 0.62-3.16% and 0.82-3.34%, respectively. Moreover, this method was successfully applied to analysis the vitamin E isomers in Moringa oleifera leaf samples.
4.Simultaneous Determination of 2- and 3-MCPD Esters in Infant Formula Milk Powder by Solid-Phase Extraction and GC-MS Analysis.
J AOAC Int. 2016 Apr 7. [Epub ahead of print]
The objective of this study was to establish a method for detecting fatty acid esters of chloropropanols [including 2-monochloropropane-1,3-diol (2-MCPD) ester and 3-monochloropropane-1,2-diol (3-MCPD) ester] in infant milk powder using isotope dilution and GC-MS. The fat fraction in infant milk powder samples was extracted and treated with sodium methylate-methanol to cleave the ester bonds of the 2- and 3-MCPD esters. The resultant 2- and 3-MCPDs in the samples were purified with matrix solid-phase liquid-liquid extraction and derivatized with heptafluorobutyryl imidazole for GC-MS analysis. Standard samples of deuterium isotope-labeled 2- and 3-MCPD palmitic acid double esters and stearic acid double esters were used as the internal standards. We also detected 2- and 3-MCPD ester contents in 88 commercial samples of infant formula milk powder using this system. The detection system we established showed a good linearity of 2- and 3-MCPD ester contents in serially diluted standard solutions within the concentration range 25-1000 μg/L, with r2 > 0.
