Bacterial Phylum Actinobacteria

Bacterial Phylum Actinobacteria

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...

Bacterial Phylum Verrucomicrobiota

Bacterial Phylum Verrucomicrobiota

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,...

Deep Sea Microbial Ecology

Deep Sea Microbial Ecology

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...

Microbiota of the Large Intestine

Microbiota of the Large Intestine

The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Anoxygenic Phototrophic Bacteria

Anoxygenic Phototrophic Bacteria

Anoxygenic phototrophic bacteria are a diverse group of microorganisms that perform photosynthesis without producing oxygen. They primarily include purple sulfur bacteria, purple nonsulfur bacteria, green sulfur bacteria, and green nonsulfur bacteria. These bacteria are classified into the Gammaproteobacteria, Alphaproteobacteria, Betaproteobacteria, Chlorobi, and Chloroflexi lineages, each with distinct physiological and ecological adaptations.Purple sulfur bacteria belong to the...

Area of Science:

Microbiology
Bacteriology
Taxonomy

Background:

Soil ecosystems harbor diverse microbial communities.
Actinobacteria, including the genus Microbacterium, play significant roles in soil environments.
Accurate taxonomic classification is crucial for understanding microbial diversity and function.

Purpose of the Study:

To isolate and characterize a novel actinobacterium from a Korean agricultural soil sample.
To determine the taxonomic position of the isolate using polyphasic characterization.
To propose a new species within the genus Microbacterium.

Main Methods:

Isolation and cultivation of bacteria from soil samples.
Polyphasic taxonomic analysis including phenotypic, chemotaxonomic, and genotypic methods.
Phylogenetic analysis based on 16S rRNA gene sequencing.
DNA-G+C content determination and DNA-DNA hybridization.

Main Results:

A Gram-positive, short rod-shaped actinobacterium, strain MSL-04(T), was isolated.
Chemotaxonomic data (peptidoglycan, menaquinones, fatty acids) indicated placement within the genus Microbacterium.
Phylogenetic analysis showed MSL-04(T) is closely related to Microbacterium ulmi but distinct.
DNA-DNA relatedness values were below 70%, confirming genomic distinctness.
The G+C content of the DNA was 71.0 mol%.

Conclusions:

Strain MSL-04(T) represents a novel species within the genus Microbacterium.
The proposed name for the novel species is Microbacterium kribbense sp. nov.
The type strain is MSL-04(T) (=KCTC 19269(T) =DSM 19265(T)).
