CO₂‐mediated bloater defect can be induced by the uncontrolled growth of <i>Enterobacteriaceae</i> in cucumber fermentation

Enterobacteriaceae are known to proliferate in cucumber juice, deriving energy from the fermentation of sugars organic acids and ethanol, theoretically generating carbon dioxide (CO2). We hypothesized that CO2 produced by indigenous early stage accumulates fermenting fruits causing bloater defect. The ability seven Enterobacteriaceae, cucumber, grow produce juice medium (CJM), a sterile model system for fermentation, was characterized. induction defect conducted with pasteurized acidified also evaluated. generation times CJM ranged between 0.25 8.20 h resulted (CO2) production estimated amounts 7.22–171.5 mM. Enterobacter cancerogenus nimipressuralis were among bacteria most least CJM, respectively, at mM concentrations 171.58 ± 42.96 16.85 6.53. Inoculation E. cucumbers 138 27 CO2, respectively. Such 2% hydrogen fermentations. A index 25.4 17.4 calculated fermented nimipressuralis, whereas no observed collected uninoculated control jars. It is concluded metabolic activity can sufficient fermentations induce
