Complete genome sequence of Enterococcus faecalis LD33, a bacteriocin-producing strain

Area of Science:

• Microbiology
• Genomics
• Food Science

Background:

• Enterococcus faecalis is a common bacterium found in fermented foods.
• Understanding the genetic makeup of specific strains is crucial for food safety and biotechnology.
• Strain LD33 was isolated from traditional fermented cream in Inner Mongolia, China.

Purpose of the Study:

• To perform whole-genome sequencing of the Enterococcus faecalis LD33 strain.
• To identify genetic elements responsible for bacteriocin production.
• To investigate genes associated with the respiratory chain.

Main Methods:

• Whole-genome sequencing using Illumina Hiseq and PacBio RSII platforms.
• Bioinformatic analysis of the obtained genome sequence.

Main Results:

• The complete genome consists of a single circular chromosome.
• The GC content of the genome is 37.58%.
• Identified genetic elements related to bacteriocin production and respiratory chain functions were found.

Conclusions:

• The genome sequencing provides valuable insights into the genetic potential of Enterococcus faecalis LD33.
• The identified genes offer a basis for further research into bacteriocin applications and metabolic pathways.
