Catenulispora fulva sp. nov., isolated from forest soil

Area of Science:

• Microbiology
• Actinobacteria Taxonomy
• Genomic Analysis

Background:

• Actinomycetes are crucial soil microorganisms with diverse metabolic capabilities.
• The genus Catenulispora comprises actinobacteria with distinct phylogenetic and chemotaxonomic features.
• Accurate classification of novel strains is essential for understanding microbial diversity and ecological roles.

Purpose of the Study:

• To isolate and characterize a novel actinomycete strain from a forest soil sample.
• To determine the taxonomic position of the isolate within the genus Catenulispora using a polyphasic approach.
• To propose a new species designation for the novel isolate.

Main Methods:

• Isolation of actinomycete strain SA-246T from forest soil.
• Polyphasic characterization including morphological, chemotaxonomic (peptidoglycan, whole-cell sugars, menaquinones), and 16S rRNA gene sequencing.
• Phylogenetic analysis based on 16S rRNA gene sequences.

Main Results:

• Strain SA-246T exhibited morphological and chemotaxonomic characteristics consistent with the genus Catenulispora.
• 16S rRNA gene sequence analysis showed highest similarity to Catenulispora yoronensis TT N02-20T (98.7%).
• Phylogenetic analyses confirmed strain SA-246T as a distinct lineage within the Catenulispora genus.

Conclusions:

• Strain SA-246T represents a novel species of the genus Catenulispora.
• The proposed name for the novel species is Catenulispora fulva sp. nov.
• The type strain is SA-246T (=KACC 17878T = NBRC 110074T).
