Its 16S rDNA nucleotide sequence is shown in SEQ ID NO. 1. The genome of strain FBEL010 contains a gene encoding the alcohol-acyltransferase AAT, the nucleotide sequence of which is shown in SEQ ID NO. 2. This strain is used in the preparation of fermented fruit and vegetable juices. The prepared fermented fruit and vegetable juices have a total ester content ≥150 μg / L, and significantly increased levels of hexyl acetate and ethyl butyrate fruit aroma components. Testing according to national standards showed no pathogenic bacteria, and the content of contaminating bacteria was within acceptable limits. The content of heavy metals (lead, arsenic, mercury) and additives meets national standards, making it suitable for use as a beverage. This strain can also be used to prepare fermented fruit and vegetable juices such as strawberry, lychee, pineapple, and cucumber.
