Oenococcus oeni strains from traditional Italian red wines of the Basilicata region were investigated on the basis of their physiological and molecular response to different temperatures and ethanol concentrations. All strains were highly resistant to different ethanol concentrations and it has been observed that 7% ethanol was able to stimulate the growth(More)
Several extrinsic factors, like drugs and chemicals, can foster autoimmunity. Tetracyclines, in particular oxytetracycline (OTC), appear to correlate with the emergence of immune-mediated diseases. Accumulation of OTC, the elective drug for gastrointestinal and respiratory infectious disease treatment in broiler chickens, was reported in chicken edible(More)
In this study, we compared different total protein extraction protocols to achieve highly efficient isolation and purification of total proteins for the specific protein profiling of Oenococcus oeni. The sodium dodecyl sulfate-polyacrylamide gel electrophoresis patterns obtained for the different extraction protocols revealed not only a qualitative similar(More)
The aim of this study was a reliable intra-species discrimination and strain biodiversity in Oenococcus oeni populations of two different Aglianico wineries by molecular, biochemical, and physiological characterization. Pulsed field gel electrophoresis (PFGE) analysis revealed a high polymorphism related to the origin (winery) of strains, while differential(More)
Twenty-two Brevibacterium linens strains isolated from ‘Pecorino di Filiano’ cheese ripened in two different environments (natural cave and storeroom) were characterized and differentiated for features of technological interest and by genotypic methods, in order to select strains with specific features to be used as surface starter cultures. Results showed(More)
Lactobacillus sakei is widely used as starter in the production process of Italian fermented sausages and its growth and survival are affected by various factors. We studied the differential expression of genome in response to different stresses by the fluorescent differential display (FDD) technique. This study resulted in the development and optimization(More)
Two young patients (a brother and his sister) with low ASA levels who had myoclonic seizures since the age of eight years, were investigated by means of electrophysiological, neuroradiological and laboratory tests and submitted to a physical examination. In both patients, the disease started at the age of eight years with drug resistent myoclonic seizures.(More)
