Summary
Complete genome sequencing of beer-spoiling lactic acid bacteria revealed that plasmids are key to their spoilage ability. This finding is crucial for understanding and preventing beer spoilage in the brewing industry.
Area of Science:
- Microbiology
- Genomics
- Food Science
Background:
- Lactic acid bacteria (LAB) are significant spoilage organisms in the brewing industry.
- Understanding the genetic basis of LAB spoilage is critical for maintaining beer quality.
Purpose of the Study:
- To sequence the complete genomes of key beer-spoiling LAB strains.
- To identify the genetic factors contributing to the beer-spoiling capabilities of these bacteria.
Main Methods:
- Single-molecule real-time (SMRT) sequencing was employed to obtain high-quality bacterial genomes.
- Comparative genomic analysis was performed on the obtained genomes.
Main Results:
- Complete genome sequences were successfully generated for Lactobacillus paracollinoides, Lactobacillus lindneri, and Pediococcus claussenii.
- Genomic analysis highlighted the significant role of plasmids in conferring beer-spoiling traits.
Conclusions:
- Plasmids are essential components of the genomic makeup responsible for the beer-spoiling phenotype in these LAB.
- Targeting plasmid-associated genes could be a viable strategy for controlling beer spoilage.

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

00:46Genomic DNA in Prokaryotes
49.8K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
