Summary
A novel pink bacterium, Adhaeribacter swui sp. nov., was identified from wet mud. This aerobic, Gram-negative bacterium expands the known diversity within the Adhaeribacter genus.
Area of Science:
- Microbiology
- Bacteriology
- Phylogenetics
Background:
- The genus Adhaeribacter comprises aerobic, Gram-negative bacteria with limited species described.
- Understanding bacterial diversity is crucial for ecological and biotechnological applications.
Purpose of the Study:
- To characterize and classify a novel bacterial isolate from a wet mud environment.
- To determine the phylogenetic and chemotaxonomic relationship of the isolate to known Adhaeribacter species.
Main Methods:
- Isolation and cultivation of strain 17mud1-7T from wet mud.
- Physicochemical characterization including growth conditions, Gram staining, and enzymatic tests.
- Phylogenetic analysis using 16S rRNA gene sequencing.
- Chemotaxonomic analysis including respiratory quinone, major fatty acids, and polar lipid profiles.
- DNA G+C content determination.
Main Results:
- Strain 17mud1-7T is a pink, aerobic, catalase- and oxidase-positive, Gram-negative bacterium.
- Optimal growth occurred at 28°C, pH 7.0, and without added NaCl.
- Phylogenetic analysis showed 96.4% 16S rRNA gene sequence similarity to Adhaeribacter aerophilus 6424S-25T.
- Chemotaxonomic data, including MK-7 and specific fatty acids, aligned with the Adhaeribacter genus.
- DNA G+C content was 45.9 mol%.
Conclusions:
- Strain 17mud1-7T represents a novel species within the genus Adhaeribacter.
- The proposed name for this new species is Adhaeribacter swui sp. nov.
- The type strain is 17mud1-7T (=KCTC 52873T=NBRC 112824T).

01:24DNA Isolation
45.2K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

01:20Overview Of Cell Separation And Isolation
7.7K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

01:19Cyclic Processes And Isolated Systems
3.5K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...
