Abstract

Lactobacillus plantarum is widely found in fermented foods and has various phenotypic and genetic characteristics to adapt to the environment. Here we report the complete annotated genome sequence of the L. plantarum strain JBE245 (= KCCM43243) isolated for malolactic fermentation of apple juice. The genome comprises a single circular 3,262,611 bp chromosome with 2907 coding regions, 45 pseudogenes, and 91 RNA genes. The genome contains 4 malate dehydrogenase genes, 3 malate permease genes and various types of plantaricin-synthesizing genes. These genetic traits meet the selection criteria of the strains that should prevent the spoilage of apple juice during fermentation and efficiently convert malate to lactic acid.

발효 식품에서 널리 발견되는 Lactobacillus plantarum은 환경에 적응하기 위한 다양한 표현형 및 유전적 특성을 가지고 있다. 우리는 사과 주스의 malolactic 발효를 위해 선발한 L. plantarum JBE245 (= KCCM43243) 유전체의 전체 염기서열과 주석을 보고한다. 유전체는 2907개의 암호화 된 영역, 45개의 위유전자, 91개의 RNA 유전자를 포함한 단일 원형 염색체로 구성되었으며 그 크기는 3,262,611 bp였다. 이 유전체는 4개의 malate dehydrogenase 및 3개의 malate permease 유전자들과 함께 다양한 종류의 plantaricins 합성 유전자들을 포함하고 있었다. 이러한 유전적 특성은 발효 동안 사과 주스의 부패 방지와 사과산(malate)의 젖산(lactate)으로의 효율적 전환이 요구되는 균주의 선발 기준과 잘 부합되었다.
