Later this bacteria will produce enzyme and they will die of fermentation process. On this stage, the lactic acids will reach 25
Other groups of bacteria that are Lactobacillus plantarum and Lactobacillus cucumeris will continue the fermentation process until lactic acid level of 1.5-2% is attained. Must be remember that excessive salting will inhibit this bacteria activities and remember to not put it in fridge during this stage. This stage will take 10 to 30 days depending on the room temperature.
