A Study on the pH Characterization for Microbial Fermentation in Tomato Juice

다국어 초록 (Multilingual Abstract)

This study was conducted to know the behavior of pH behavior in the tomato juices to find out an effective medium for microbial cultivation. Bacterial culture media is a material consist a mixture of nutrients used to grow microorganisms on or in it. In addition, microbial culture media can also be used for isolation, propagation, testing the nature physiological, and calculation of the number of microorganisms. Fresh tomato juice is used for basic ingredient, therein added salt, sugar and EM (Effective Microbial). The fermented solution placed in a room with a temperature of 40℃. Data retrieval before the pH value reached a constant value is done every 12 hours, after constant rate data collection was done every 24 hours. The pH value has been steady after 372 hours of fermentation process (15.5 days). From the results obtained that the amount of additional ingredient which added into tomato juice does not affect final pH value of solution. Thereby the most effective treatment for microbial cultivation media is treatment number four.
