Metabolic engineering of threonine catabolism enables Saccharomyces cerevisiae to produce propionate under aerobic conditions

Biotechnology Journal, 2022
Propionate is widely used as a preservative in the food and animal feed industries. Propionate is currently produced by petrochemical processes, and fermentative production of propionate remains challenging.

Short-chain fatty acids, acetate and propionate, directly upregulate osteoblastic differentiation

International Journal of Food Science and Nutrition, 2022
Short-chain fatty acids, including acetate, propionate, and butyrate are metabolites of dietary fibre produced by microbiota in the large intestine, have been proposed to contribute to effects on bone homeostasis.

Measurement of propionate turnover in vivo using sodium [2H5]propionate and sodium [13C]propionate

Clinica Chimica Acta, 1989
The outcome for children with inherited disorders of propionate metabolism is poor. To facilitate development of improved treatment in these conditions, we described techniques for the estimation of the rate of production and removal of propionate in vivo.

Sources of propionate in inborn errors of propionate metabolism

Metabolism, 1990
Amino acids are widely regarded as the most important sources of propionate in disorders of propionate metabolism. Propionate production was measured in the fasting state by continuous infusion of sodium [1-13C]propionate in three children with methylmalonic acidemia (MMA) and three with propionic acidemia (PA).

Survey of baked goods for propionic acid and propionates

Food Additives and Contaminants, 1996
One hundred and thirty samples comprising bread (64), hamburger buns (33), pittas (16), cakes (9) and Christmas puddings (8) from various retail outlets in the UK, have been analysed for the preservative propionic acid. Only one sample of bread, two samples of hamburger buns and three samples of pitta contained propionic acid in excess of 1000 mg/kg ...

Syntrophic Propionate Oxidation

1990
In vivo high-resolution NMR with the Gram-negative Syntrophobacter wolinii and a Gram-positive syntrophic propionate oxidizing organism, indicated the involvement of an oxaloacetate: propionyl-CoA transcarboxylase in propionate oxidation. This finding was confirmed by enzyme measurement in cell-free extracts.

The gut microbiota metabolite propionate ameliorates intestinal epithelial barrier dysfunction-mediated Parkinson's disease via the AKT signaling pathway.

NeuroReport, 2021
OBJECTIVE Parkinson's disease is a common neurodegenerative disease. Here, we investigated the protective effect and potential mechanisms of propionate on the intestinal epithelial barrier in mice with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP ...

Propionic Acid

2020
During the past years, there has been a growing interest in the bioproduction of propionic acid by Propionibacterium. One of the major limitations of the existing models lies in their low productivity yield. Hence, many strategies have been proposed in order to circumvent this obstacle.

High levels of butyrate and propionate in early life are associated with protection against atopy

Allergy. European Journal of Allergy and Clinical Immunology, 2018
Dietary changes are suggested to play a role in the increasing prevalence of allergic diseases and asthma. Short‐chain fatty acids (SCFAs) are metabolites present in certain foods and are produced by microbes in the gut following fermentation of fibers ...

Metabolism of short‐chain fatty acid propionate induces surface expression of NKG2D ligands on cancer cells

The FASEB Journal, 2020
SCFAs are primarily produced in the colon by bacterial fermentation of nondigestible carbohydrates. Besides providing energy, SCFAs can suppress development of colon cancer. The mechanism, however, remains elusive.
