Area of Science:

• Microbiology
• Environmental Science
• Genomics

Background:

• Stutzerimonas balearica, previously known as Pseudomonas balearica, primarily inhabits oil-polluted environments.
• This bacterium's ability to degrade pollutants makes it a candidate for bioremediation, but its diversity remains largely uncharacterized.

Purpose of the Study:

• To investigate the genetic diversity of Stutzerimonas balearica strains from various origins.
• To reevaluate nucleotide signatures and variations in 16S rRNA genes.
• To identify novel strains and assess their biodegradation capabilities.

Main Methods:

• Genome sequencing and analysis of Stutzerimonas balearica strains.
• Screening of public databases for 16S rRNA gene sequences.
• Genomic and phenotypic analyses of aromatic compound degradation.

Main Results:

• Stutzerimonas balearica exhibits significant diversity with an open pan-genome.
• 158 additional strains were identified via 16S rRNA screening, with only 23% correctly identified.
• The species is widespread, predominantly in aquatic and petroleum-polluted environments, possessing varied aromatic compound degradation abilities.

Conclusions:

• Stutzerimonas balearica is a more diverse species than previously recognized.
• Its genomic plasticity and degradation capabilities support its role in bioremediation.
• Further research into its biology and diversity will enhance its application potential.
