This research was conducted to isolate, screen and identifyyeast strain capable ofproducing high quality fermented watermelon juice. The strain Saccharomyces cerevisiae M11 was selected basedon the content of alcohol, aldehyde, phenolic total, anthocynine, and antioxidant capacity in fermented watermelon juice and identified by sequencing region of ITS (Internal Transcribed Spacer Regions). The results showed that the strain M11produced highest content of alcohol (11.6 ± 0.1), phenolic total (0.06mg GAE/ml), anthocynine (0.589 ± 0.012 mg/l), and antioxidant capacity (0.589 ± 0.012 mg/l) while theanother strains (M2, M7 and M14)producedlowest content of aldehyde (57.7 ± 2.68 mg/lethanol 100)in fermented product.
