Patagonian red wines: selection of Lactobacillus plantarum isolates as potential starter cultures for malolactic fermentation.
World J. Microbiol. Biotechnol. 29(9) , 1537-49, (2013) The aim of this study was to evaluate fifty-three Lactobacillus plantarum isolates obtained from a Patagonian red wine, molecularly identified and typified using RAPD analysis, in order to select starter cultures for malolactic fermentation (MLF). The results... |

Characterization of a tannase from Emericella nidulans immobilized on ionic and covalent supports for propyl gallate synthesis.
Biotechnol. Lett. 35(4) , 591-8, (2013) The extracellular tannase from Emericela nidulans was immobilized on different ionic and covalent supports. The derivatives obtained using DEAE-Sepharose and Q-Sepharose were thermally stable from 60 to 75 °C, with a half life (t50) >24 h at 80 °C at pH 5.0. ... |

Optimization of culture medium for novel cell-associated tannase production from Bacillus massiliensis using response surface methodology.
J. Microbiol. Biotechnol. 22(2) , 199-206, (2012) Naturally immobilized tannase (tannin acyl hydrolase, E.C. 3.1.1.20) has many advantages, as it avoids the expensive and laborious operation of isolation, purification, and immobilization, plus it is highly stable in adverse pH and temperature. However, in th... |

Tannase production by Penicillium purpurogenum PAF6 in solid state fermentation of tannin-rich plant residues following OVAT and RSM.
Appl. Biochem. Biotechnol. 167(5) , 1254-69, (2012) Tannase production by newly isolated Penicillium purpurogenum PAF6 was investigated by 'one variable at a time' (OVAT) approach followed by response surface methodology (RSM). Tannin-rich plant residues were used as supporting solid substrate and sole carbon ... |
