1.Fermentation induced changes in volatile components of African oil bean (
Ohiri RC;Bassey EE Food Sci Nutr. 2017 May 15;5(4):948-955. doi: 10.1002/fsn3.481. eCollection 2017 Jul.
Fermented African oil bean (;Pentaclethra macrophylla Benth;) seed also referred to as "Ugba" is a known delicacy, mainly consumed by Africans. Human migration has also led to the introduction of this delicacy into most European and American countries. This study shows the changes in volatile components of African oil bean (;P. macrophylla Benth;) seed at different stages of fermentation. A quantity of 0.3 kg each of dehulled and sliced raw sample and cooked unfermented sample were separately ground, while 2 and 4 days fermented samples obtained by inoculating 0.6 kg of cooked, sliced and washed sample with 0.5 g of 4 days fermented seed was divided into two of 0.3 kg each and ground at the second and fourth day of fermentation. GC-MS analyses of the volatile components showed 9,12-Octadecadienoic acid (Z,Z)- and its esters as highest in raw seed, with total percentage concentration of 96.301, while 9-Octadecenoic acid, methyl ester, (E)- was highest in cooked unfermented seed, with percentage concentration 55.
2.GC-MS Analysis and Preliminary Antimicrobial Activity of
Abubakar MN;Majinda RRT Medicines (Basel). 2016 Jan 28;3(1). pii: E3. doi: 10.3390/medicines3010003.
The non-polar components of two leguminoceae species ;Albizia adianthifolia; (Schumach), and ;Pterocarpus angolensis; (DC) were investigated. GC-MS analysis of the crude ;n;-hexane and chloroform extracts together with several chromatographic separation techniques led to the identification and characterization (using NMR) of sixteen known compounds from the heartwood and stem bark of ;Albizia adianthifolia; and ;Pterocarpus angolensis; respectively. These constituents include, ;n;-hexadecanoic acid (palmitic acid) ;1;, oleic acid ;2;, chondrillasterol ;3;, stigmasterol ;4;, 24S 5α-stigmast-7-en-3β-ol ;5;, 9,12-octadecadienoic acid (;Z;,;Z;)-, methyl ester ;6;, ;trans-;13-octadecanoic acid, methyl ester ;7;, tetradecanoic acid ;8;, hexadecanoic acid, methyl ester ;9;, octadecanoic acid ;10;, tetratriacontane ;11;, 7-dehydrodiosgenin ;12;, lupeol ;13;, stigmasta-3,5-diene-7-one ;14;, friedelan-3-one (friedelin) ;15;, and 1-octacosanol ;16;.
3.Discovery and characterizaton of a novel lipase with transesterification activity from hot spring metagenomic library.
Yan W;Li F;Wang L;Zhu Y;Dong Z;Bai L Biotechnol Rep (Amst). 2016 Dec 23;14:27-33. doi: 10.1016/j.btre.2016.12.007. eCollection 2017 Mar.
A new gene encoding a lipase (designated as ;Lip-1;) was identified from a metagenomic bacterial artificial chromosome(BAC) library prepared from a concentrated water sample collected from a hot spring field in Niujie, Eryuan of Yunnan province in China. The open reading frame of this gene encoded 622 amino acid residues. It was cloned, fused with the oleosin gene and over expressed in ;Escherichia coli; to prepare immobilized lipase artificial oil body AOB-sole-lip-1. The monomeric Sole-lip-1 fusion protein presented a molecular mass of 102.4 kDa. Enzyme assays using olive oil and methanol as the substrates in petroleum ether confirmed its transesterification activity. Hexadecanoic acid methyl ester, 8,11-Octadecadienoic acid methyl ester, 8-Octadecenoic acid methyl ester, and Octadecanoic acid methyl ester were detected. It showed favorable transesterification activity with optimal temperature 45 °C. Besides, the maximal biodiesel yield was obtained when the petroleum ether system as the organic solvent and the substrate methanol in 350 mmol/L (at a molar ratio of methanol of 10.
