Pseudomonas bauzanensis sp. nov., isolated from soil

Area of Science:

• Microbiology
• Bacteriology
• Taxonomy

Background:

• The genus Pseudomonas comprises diverse Gram-negative bacteria with significant environmental and clinical roles.
• Accurate taxonomic classification is crucial for understanding bacterial diversity and function.

Purpose of the Study:

• To characterize and classify a novel bacterial isolate from industrial soil.
• To determine the phylogenetic and genotypic relationship of the isolate to known bacterial species.

Main Methods:

• Isolation and cultivation of bacteria from industrial soil.
• Phylogenetic analysis using 16S rRNA gene sequences.
• Determination of cellular fatty acid composition, major quinone, phospholipids, and genomic DNA G+C content.
• DNA-DNA relatedness studies.

Main Results:

• A novel Gram-negative, aerobic, motile rod, strain BZ93(T), was isolated.
• Phylogenetic analysis indicated close relatedness to Pseudomonas xiamenensis and Pseudomonas pertucinogena.
• Distinct cellular fatty acid profiles, ubiquinone content, and genomic DNA G+C content (61.8 mol%) were observed.
• Low DNA-DNA relatedness to closely related species confirmed its novelty.

Conclusions:

• Strain BZ93(T) represents a new species within the genus Pseudomonas.
• The proposed name for this novel species is Pseudomonas bauzanensis sp. nov.
• The type strain is BZ93(T) (=DSM 22558(T) =CGMCC 1.9095(T) =LMG 26048(T)).
