Paper Title
The Study on Species Diversity of Acetic Acid Bacteria Isolated from Traditional NIPA Sap Fermented Vinegar that Produced in the East Coast Southern Subregion of Thailand

Abstract
This study investigated the occurrence and identified the Acetic Acid Bacteria strain from samples, Traditional Nipa Sap Fermented Vinegar that Produced in the East Coast Southern Subregion of Thailand. The total of 46 isolates of Acetic Acid Bacteria strains were isolated from 17 samples of Traditional Nipa Sap Fermented Vinegar. The enrichment culture media at pH 3.5 were used to promote growth of acetic acid bacteria and the Glucose-Ethanol-Calcium- Carbonate agar was used to screen acid producing bacteria. The experiment was tested by culturing on the different carbon sources. The morphology, biochemical test and result of partial 16S rDNA sequencing analysis by Mega 7 program were used to identify all of acetic acid bacteria in this study into species. All of the 46 isolates were gram negative, rod shape, aerobic acid producing bacteria, oxidase negative and catalase positive. All of 46 strains of Acetic Acid Bacteria, 36 strains of them were routinely identified as Acetobacter pasteurianus, 2 strains of them were routinely identified as Acetobacter ghanensis and 8 strains of them were routinely identified as Komagataeibacter intermedius. Index Terms - Isolation, Identification, Acetic Acid Bacteria, Thailand.
