The application of a selected Acetobacter pasteurianus strain for traditional balsamic vinegar production was assessed. Genomic DNA was extracted from biofilms after enrichment cultures on GYC medium (10% glucose, 1.0% yeast extract, 2.0% calcium carbonate) and used for PCR/denaturing gradient gel electrophoresis, 16S rRNA gene sequencing, and enterobacterial repetitive intergenic consensus/PCR sequencing. Results suggested that double-culture fermentation is suitable for traditional balsamic vinegar acetification.
评估了一株选定的巴氏醋酸杆菌菌株在传统香醋生产中的应用。在GYC培养基(10%葡萄糖、1.0%酵母提取物、2.0%碳酸钙)上进行富集培养后,从生物膜中提取基因组DNA,并用于PCR/变性梯度凝胶电泳、16S rRNA基因测序和肠杆菌重复基因间共识/PCR测序。结果表明,双培养发酵适用于传统香醋的醋酸发酵。
