Bioconversion of conjugated linoleic acid by Lactobacillus plantarum CGMCC8198 supplemented with Acer truncatum bunge seeds oil

Abstract

Conjugated linoleic acid (CLA) isomers, 9,11-CLA and 10,12-CLA, have been proved to exhibit excellent biomedical properties for potential use in anti-cancer applications and in reducing obesity. (), which is rich in unsaturated fatty acids, including oleic acid, linoleic acid, and nervonic acid, is a new resource for edible oil. In the present study, we developed a new method for producing two CLA isomers from -seed oil by fermentation using CGMCC8198 (8198), a novel probiotics strain. Polymerase chain reaction results showed that there was a conserved linoleate isomerase (LIase) gene in 8198, and its transcription could be induced by-seed oil. Analyses by gas chromatography-mass spectrometry showed that the concentration of 9,11-CLA and 10,12-CLA in -seed oil could be increased by about 9- and 2.25-fold, respectively, after being fermented by8198.

Cognitive improvement effect of nervonic acid and essential fatty acids on rats ingestingAcer truncatum Bungeseed oil revealed by lipidomics approach

“…8 Acer truncatum Bunge seed oil (ASO), as a novel edible oil, possesses a proportion of unsaturated FAs that is up to 92% is richer in LA and OA than other edible oils including sunflower, rapeseed, grape and peanut oil. 9,10 ASO is an important woody oil, and its nutritional and economic value largely depend on its FA composition. In 2011, ASO was certified as a new food resource by the Ministry of Health of the People's Republic of China.…”

Effective Improvement of the Oxidative Stability of Acer truncatum Bunge Seed Oil, a New Woody Oil Food Resource, by Rosemary Extract

“…Considering the overall Aoil fatty acid composition, the following order was determined: Monounsaturated fatty acids (MUFA) > Polyunsaturated fatty acids (PUFA) > Saturated fatty acid (SFA). Unsaturated fatty acids (UFAs) were the most abundant in the Aoil, accounting for up to 90% of the total fatty acids ( Figure 1 C) [ 2 ]. Linoleic acid (LA, C18:2, cis (n6)) was the main fatty acid found in the Aoil ( Figure 1 D), with a content of 34.859 ± 0.2436 g/100 g. It is important to note that Aoil has a rather high content of nervonic acid, with 6.327 ± 0.1549 g/100 g.…”

“…It is a versatile, oil-producing, woody tree that is a native species widely distributed in northern China, Korea, and Japan. Unsaturated fatty acids (FAs) account up to 92% of the entire A. truncatum seed oil (Aoil) [ 2 ]. In 2011, The People’s Republic of China’s Ministry of Health certified Aoil as a new food resource [ 3 ].…”

“…This has laid a certain foundation for microbial production of Lb. plantarum [ 110 ]. In the experiment of Chen L. et al [ 111 ], dietary supplementation of conjugated CLA can increase the abundance of lipid metabolism-related bacteria and significantly reduce fat deposition in mice, further evidence of its cholesterol-lowering effect.…”
