Solubilization of gliadins for use as a source of nitrogen in the selection of bacteria with gliadinase activity.
Food Chem. 168 , 439-44, (2014) For patients with celiac disease, gliadin detoxification via the use of gliadinases may provide an alternative to a gluten-free diet. A culture medium, in which gliadins were the sole source of nitrogen, was developed for screening for microorganisms with gli... |

Optimization of Direct Lysine Decarboxylase Biotransformation for Cadaverine Production with Whole-Cell Biocatalysts at High Lysine Concentration.
J. Microbiol. Biotechnol. 25 , 1108-13, (2015) Cadaverine (1,5-diaminopentane) is an important industrial chemical with a wide range of applications. Although there have been many efforts to produce cadaverine through fermentation, there are not many reports of the direct cadaverine production from lysine... |

Use of Commercial Dry Yeast Products Rich in Mannoproteins for White and Rosé Sparkling Wine Elaboration.
J. Agric. Food Chem. 63 , 5670-81, (2015) In sparkling wines, mannoproteins released during yeast autolysis largely affect their final quality. This process is very slow and may take several months. The aim of this work was to study the effect of several commercial dry yeast autolysates on the chemic... |

Study of the matrix effects and sample dilution influence on the LC-ESI-MS/MS analysis using four derivatization reagents.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 967 , 147-55, (2014) For liquid chromatographic analysis of amino acids involving derivatization and mass-spectrometric detection, it becomes more important to evaluate the presence of matrix effects in complex samples. This is somewhat complicated for amino acid analysis where a... |

Brief Report: Human Mesenchymal Stem-Like Cells Facilitate Floating Tumorigenic Cell Growth via Glutamine-Ammonium Cycle.
Stem Cells 33 , 2877-84, (2015) How mesenchymal stem cells (MSCs) promote tumor growth remains incompletely understood. Here, we show that mesenchymal stem-like cells (MSLCs) are commonly present in malignant pleural effusion or ascites of cancer patients, where they directly interact with ... |

Comparison of amino acid derivatization reagents for LC-ESI-MS analysis. Introducing a novel phosphazene-based derivatization reagent.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 904 , 99-106, (2012) Amino acid analysis with high performance liquid chromatography with electrospray ionization mass spectrometry (LC-ESI-MS) is an emerging method. For more sensitive analysis, derivatization is used and next to commercially available derivatization reagents su... |

Tyramine biosynthesis is transcriptionally induced at low pH and improves the fitness of Enterococcus faecalis in acidic environments.
Appl. Microbiol. Biotechnol. 99(8) , 3547-58, (2015) Enterococcus faecalis is a commensal bacterium of the human gut that requires the ability to pass through the stomach and therefore cope with low pH. E. faecalis has also been identified as one of the major tyramine producers in fermented food products, where... |

Study of the mechanism behind adjuvant action of diethylethoxymethylene malonate enhancing the rectal absorption of cefmetazole and lysozyme.
J. Pharmacobiodyn. 7(9) , 607-13, (1984) Diethylethoxymethylene malonate (DEEMM) and diethyl maleate (DEM) enhanced the rectal absorption of cefmetazole in rats when studies were carried out using in vivo, in situ rectal loop and in vitro rectal everted sac method. Since an increase of cefmetazole t... |
