We have previously demonstrated that butyric acid induces cytotoxicity and apoptosis of murine thymocytes, splenic T cells, and human Jurkat T cells. Therefore, to determine the apoptotic signaling pathway induced by butyric acid, we investigated the contribution of reactive oxygen species (ROS), mitochondria, ceramide, and mitogen-activated protein kinases in butyric acid-induced human Jurkat ...

We previously reported that butyric acid, an extracellular metabolite from periodontopathic bacteria, induced apoptosis in murine thymocytes, splenic T cells, and human Jurkat T cells. In this study, we examined the ability of butyric acid to induce apoptosis in peripheral blood mononuclear cells (PBMC) and the effect of bacterial lipopolysaccharide (LPS) on this apoptosis. Butyric acid signifi...

A mathematical model was developed to describe batch and continuous fermentation of glucose to organic acids with Clostridium tyrobutyricum. A modified Monod equation was used to describe cell growth, and a Luedeking-Piret equation was used to describe the production of butyric and acetic acids. Using the batch fermentation equations, models predicting butyric acid selectivity for continuous fe...

In making alternative fuels from biomass feedstocks, the production of butyric acid is a key intermediate in the two-step production of butanol. The fermentation of glucose via Clostridium tyrobutyricum to butyric acid produces undesirable byproducts, including lactic acid and acetic acid, which significantly affect the butyric acid yield and productivity. This paper focuses on the production o...

The properties of butyric acid, and the role it plays in the gastrointestinal tract, have been known for many years. However, the newest research shows that butyric acid still remains a molecule with a potential that has not as yet been fully exploited. The article provides an outline of relevant up-to-date knowledge about butyric acid, and presents the expert position on the clinical benefits ...

The aim of this investigation was micropropagation of Quercus brantii L. via culture of terminal and lateral buds for mass production of this plant. The plant materials were collected from Fars province Iran in spring and summer seasons. After surface sterilization and the removal of phenol materials from the explants, they were transferred into different culture media containing different conc...

Butyric acid is detected in periodontal pockets and is thought to be involved in the initiation and progression of periodontal disease. We examined the effects of sodium bicarbonate on the butyric acid-induced epithelial cell damage. The human gingival carcinoma cell line Ca9-22 was cultured in medium that contained butyric acid with or without sodium bicarbonate. The viability of cells treated...

background and objectives: butyric acid has many applications in chemical, food and pharmaceutical industries. applications of butyric acid are as an additive to food, flavorings, varnishes, perfumes, pharmaceuticals and disinfectants. butyric acid concentrations have positive impact on the quality control of milk, yogurt and other probiotic dairy products. the present investigation was underta...

Gamma-hydroxybutyrate / butyric acid, ambiguously called GHB, presents some unique challenges for analysis due in part to its acidity, high polarity, and high solubility in aqueous solution. Its chemistry is complicated by its conversion into the corresponding lactone compound, where the GHB molecule condenses to form a cyclic ester with a five-membered ring. This compound, gamma-butyrolactone ...

We have previously demonstrated that human gingival fibroblasts rescue butyric acid-induced T-cell apoptosis via proinflammatory cytokines such as interleukin 6 (IL-6) and IL-11, which are produced by fibroblasts stimulated with butyric acid. In this study, we determined if T-cell adhesion to human gingival fibroblasts influenced the susceptibility of T cells to butyric acid-induced apoptosis. ...
