The present study describes a novel microcarrier substrate consisting of a swellable, copolymer of styrene and divinylbenzene, derivatized with trimethylamine. The co-polymer trimethylamine microcarriers support the growth of a number of different cell lines - Madin Darby Bovine Kidney, Madin-Darby Canine Kidney, Vero and Cos-7 - under serum-free conditions, and human diploid fibroblasts in ser...

Generally the main component of fishy flavor is considered to be trimethylamine. On the other hand, carbonyl compounds, produced from oxidation of polyunsaturated fatty acid by lipoxygenase or by autoxidation, might have some contribution to the fishy flavor. Since sardine skin contains high levels of polyunsaturated fatty acids and lipoxygenase, carbonyl compounds may be generated more easily ...

this present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. the results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive whereas egg production, feed...

The nonfermentative Alteromonas putrefaciens NCMB 1735 grew anaerobically in defined media with trimethylamine oxide as external electron acceptor. All amino acids tested, except taurine and those with a cyclic or aromatic side chain, were utilized during trimethylamine oxide-dependent anaerobic growth. Lactate, serine, and cysteine (which are easily converted to pyruvate) and glutamate and asp...

Nine marine methanogenic Methanococcoides strains, including the type strains of Methanococcoides methylutens, M. burtonii, and M. alaskense, were tested for the utilization of N-methylated glycines. Three strains (NM1, PM2, and MKM1) used glycine betaine (N,N,N-trimethylglycine) as a substrate for methanogenesis, partially demethylating it to N,N-dimethylglycine, whereas none of the strains us...

To better understand why amines catalyze the reactivity of SiOH with silanes, we examined adsorption trimethylamine under a low pressure (10–9–10–8 mbar) and temperature (105–160 K) on water-terminated (H,OH)-Si(001), which is both model surface for studies promising starting substrate atomic layer deposition. Trimethylamine bonding configurations were determined by combining real-time synchrot...

This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens.

Background: During the transit of digested animal source foods, gut microbiota synthesize metabolites that can affect the body cells. One of these metabolites, i.e. Trimethylamine (TMA) that is an intermediary metabolite, ultimately leads to the production of Trimethylamine N-oxide (TMAO). Several studies have been conducted to show the association between TMAO and different diseases. This arti...

The present study was designed to identify the volatile constituents across the oestrous cycle of bovine in order to detect oestrous-specific chemical signal. The bovine saliva was extracted with diethyl ether (1 : 1 ratio, v/v) and analysed by gas chromatography-linked mass spectrometry. Numerous compounds were identified during oestrous cycle of bovine saliva. Among these, the compounds, name...
