Sun, Shuyang published the artcileSelection of a versatile Lactobacillus plantarum for wine production and identification and preliminary characterisation of a novel histamine-degrading enzyme, Related Products of alcohols-buliding-blocks, the main research area is Lactobacillus wine histamine degrading enzyme.
In this study, a desirable and versatile Lactobacillus plantarum strain possessing great ability of L-malic acid consumption, biogenic amine degradation and resistance to wine harsh environment was obtained through successive screenings. Malolactic fermentation (MLF) in contaminated grape wine and cherry wine (supplemented with histamine, tyramine and cadaverine) conducted by this strain was finished within 24 and 18 days, resp., and the concentration of histamine, tyramine and cadaverine was decreased by over 57% following MLF. The enzyme from L. plantarum responsible for the amine degradation was purified to homogeneity by four steps including cell disruption, ammonium sulfate fractionation, an anion chromatog. and a gel filtration chromatog. Such enzyme was identified as glyceraldehyde-3-phosphate dehydrogenase (GAPDH) after N-terminal sequence anal. and protein Blast, a tetramer enzyme with a subunit mol. weight of 36 kDa. The optimum values of pH and temperature of this enzyme were at pH 7.5 and 40°C, and stable between pH 5.5-8.5 and 30-50°C.
International Journal of Food Science and Technology published new progress about Biogenic amines Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 97-67-6 belongs to class alcohols-buliding-blocks, name is (S)-2-hydroxysuccinic acid, and the molecular formula is C4H6O5, Related Products of alcohols-buliding-blocks.
