Hydrolysis of particulate tributyrin in a fluidized lipase reactor
Biotechnology and Bioengineering, 1975AbstractPancreatic lipase has been immobilized onto stainless steel beads by adsorption followed by crosslinking, and onto polyacrylamide by covalent bonding. The activities of the two types of immobilized enzyme toward the particulate substrate, tributyrin emulsion droplets, were determined experimentally, and rate constants based on Michaelis‐Menten ...

OAT lipase is located in the outer pericarp layers of the groat and can be removed by wet-brushing1. Using this technique with 20 gm. of groats per 100 ml. distilled water, a suspension is obtained which contains c. 98 per cent of the total active lipase.

Effect of Tributyrin on Circulation and Respiration.
Acta Physiologica Scandinavica, 1957Summary.The effects of tributyrin on circulation and respiration have been studied by injection of a tributyrin emulsion.On intravenous injection, the effect of tributyrin on circulation is characterized by rapidly appearing bradycardia and a fall in blood pressure, followed by a rise in blood pressure.Bradycardia and the fall in blood pressure are ...

Effects of tributyrin on the gastric mucosa in the rat
Nutrition Research, 1993Abstract The physiological and biochemical characteristics of the non-secretory zone of gastric mucosa have been studied in rats adapted to a semi-purified diet containing 5% tributyrin. The tributyrin diet induced an hypertrophy of the forestomach, whereas the glandular zone was unaffected.

Clinical and pharmacologic study of tributyrin: an oral butyrate prodrug
Cancer Chemotherapy and Pharmacology, 2003Butyrate is a small polar compound able to produce terminal differentiation and apoptosis in a variety of in vitro models at levels above 50-100 microM. Previously our group demonstrated that daily oral administration of the prodrug, tributyrin, is able to briefly achieve levels >100 microM.

Effect of ammonia on the anaerobic hydrolysis of cellulose and tributyrin
Biomass and Bioenergy, 2012Abstract Ammonia nitrogen is one of the most common inhibitors in the anaerobic digestion of complex wastes containing high concentrations of ammonia like animal manures, blackwater and waste oil from gastronomy. The inhibiting effect of ammonia on methanogenesis has been well established.

An investigation on the use of tributyrin nanoemulsions for docetaxel delivery
Journal of Drug Delivery Science and Technology, 2008Tributyrin, an oil with anticancer properties, is a good solubilizer for docetaxel, an agent used in the treatment of several cancers. In this paper, the interaction between tributyrin and docetaxel was investigated in vitro in search of a potential synergistic effect. Then, nanosized emulsions (ca.

Hydrolysis of emulsified tributyrin by porcine pancreatic lipase
Enzyme and Microbial Technology, 1988Abstract A methodology is presented for characterizing the size distribution and calcium content of a tributyrin emulsion. With this procedure, lipolytic activity was monitored as a function of tributyrin interface concentration. Increasing interface concentration at low values accelerated the hydrolysis rate, and decreasing rates were observed as ...

The identification of radiolytic decomposition products from tributyrin
Journal of the American Oil Chemists' Society, 1977Abstract and SummaryIn order to facilitate the detection of radiolytic products of triglycerides which may be of higher molecular weight than their precursor, a low molecular weight triglyceride, tributyrin, was selected as a model system, and gel permeation chromatography was used to effect their separation.

A note on hydrolysis of tributyrin by Branhamella and Neisseria
Journal of Applied Bacteriology, 1987Sixty‐three strains of Branhamella and Neisseria were tested by two methods for their ability to hydrolyse glycerol tributyrate. After the conventional plate test, gas liquid chromatographical (GLC) analysis of the agar medium was carried out to detect ...
