Summary
A novel aerobic bacterium, Tersicoccus solisilvae sp. nov. (36AT), was isolated from India. Phylogenetic and chemotaxonomic analyses confirm it represents a new species within the Tersicoccus genus.
Area of Science:
- Microbiology
- Bacterial Taxonomy
- Genomics
Background:
- The genus Tersicoccus currently contains only one species, Tersicoccus phoenicis.
- Isolation of novel bacterial strains is crucial for understanding microbial diversity and potential applications.
Purpose of the Study:
- To characterize a newly isolated bacterial strain, 36AT, from India.
- To determine the taxonomic position of strain 36AT within the genus Tersicoccus using polyphasic characterization.
Main Methods:
- 16S rRNA gene sequence analysis for phylogenetic placement.
- DNA-DNA hybridization to assess genetic relatedness.
- Chemotaxonomic analyses including cell-wall composition, polar lipids, isoprenoid quinones, and fatty acid profiles.
- Biochemical tests for physiological characterization.
Main Results:
- Strain 36AT is a Gram-positive, aerobic, non-motile coccoid bacterium.
- 16S rRNA gene sequence analysis showed highest similarity to Tersicoccus phoenicis (98.9%), but DNA-DNA relatedness was low (31.9±0.8%).
- Chemotaxonomic and biochemical data supported the differentiation of strain 36AT from existing species.
Conclusions:
- Strain 36AT represents a novel species within the genus Tersicoccus.
- The proposed name for this new species is Tersicoccus solisilvae sp. nov.
- The type strain is 36AT (=KCTC 33776T=CGMCC 1.15480T).

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

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...

571
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...

The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...

Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...
