Thirty-five glycerol-assimilating bacteria have recently been isolated from soil samples. Amplified ribosomal DNA restriction analysis revealed that these strains are grouped into four genetically different types of bacteria. Gas chromatography-mass spectrometry analysis of glycerol metabolites produced by the three selected strains (strains HH7, HH12, and HH31) revealed that extracts of culture liquid with ethyl acetate contains acetyl monoglyceride (monoacetin), which has not previously been reported as a glycerol metabolite and is used as a solvent, plasticizer, and food additive, as well as for other industrial purposes. The sequence analyses of the 16S rRNA genes from the selected strains showed that all of them belong to the Enterobacteriaceae.

The lactating mammary gland strongly induces de novo lipogenesis (DNL) to support the synthesis of fatty acids, triglycerides, and cholesterol found within milk. In monogastric species, glucose is a major substrate utilized for DNL within the lactating mammary gland and must be efficiently taken up and processed to supply cytosolic acetyl-CoA for DNL. Along with the enzymes of the DNL pathway, the glycolytic enzyme, Aldolase C (Aldoc), is transcriptionally upregulated and is highly expressed during lactation in the mammary gland, suggesting a role for Aldoc in lactation.

High temperatures cause abnormal energy metabolism and inhibit the growth of fish in aquaculture. However, the mechanism of energy metabolism under chronic heat stress is still unknown. In this study, largemouth bass (Micropterus salmoides, LMB) was treated with 25℃, 29℃, and 33℃ for 8 weeks.

Acetyl-TAG (3-acetyl-1,2-diacylglycerol), unique triacylglycerols (TAG) possessing an acetate group at the -3 position, exhibit valuable properties, such as reduced viscosity and freezing points. Previous attempts to engineer acetyl-TAG production in oilseed crops did not achieve the high levels found in naturally producing seeds. Here, we demonstrate the successful generation of camelina and pennycress transgenic lines accumulating nearly pure acetyl-TAG at 93 mol% and 98 mol%, respectively.

Background: ()-5-hydroxy-7-methoxy-3-(2-hydroxybenzyl)-4-chromanone (HMC), a homoisoflavonoid isolated from , has significant anti-adipogenesis potential; it regulates adipogenic transcription factors. However, whether HMC improves hepatic steatosis in hepatocytes remains vague. This study investigated whether HMC ameliorates hepatic steatosis in free fatty acid-treated human hepatocellular carcinoma (HepG2) cells, and if so, its mechanism of action was analyzed.
