DNA Isolation

DNA Isolation

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...

DNA Isolation

DNA Isolation

DNA from cells is required for many biotechnology and research applications, such as molecular cloning. To remove and purify DNA from cells, researchers use various methods of DNA extraction. While the specifics of different protocols may vary, some general concepts underlie the process of DNA extraction.

Overview Of Cell Separation And Isolation

Overview Of Cell Separation And Isolation

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.

Cyclic Processes And Isolated Systems

Cyclic Processes And Isolated Systems

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...

Techniques for Isolation of Pure Cultures

Techniques for Isolation of Pure Cultures

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...

Reduced Mass Coordinates: Isolated Two-body Problem

Reduced Mass Coordinates: Isolated Two-body Problem

In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Area of Science:

Marine microbiology
Coral reef ecology
Bacterial symbiosis

Background:

Actinobacteria are ubiquitous in marine environments, inhabiting water and sediments.
They engage in symbiotic relationships with various marine organisms, including corals.
Previous research indicates a common association between actinobacteria and coral hosts.

Purpose of the Study:

To isolate and identify actinobacteria associated with temperate stony corals.
To investigate the prevalence of specific actinobacterial groups within coral microbiomes.

Main Methods:

Isolation of actinobacterial strains from three stony coral species: *Pocillopora damicornis*, *Acropora hyacinthus*, and *Acropora muricata*.
Identification and classification of isolated strains, focusing on mycolic acid-containing genera.

Main Results:

Forty-nine actinobacterial strains were successfully isolated from the coral samples.
Over 60% of the isolates belonged to mycolic acid-containing genera, with a notable presence of the family *Mycobacteriaceae*.
This study reinforces the global prevalence of actinobacteria in association with coral hosts.

Conclusions:

Temperate stony corals harbor a diverse actinobacterial community.
The *Mycobacteriaceae* family is a significant component of the coral-associated actinobacteria.
Actinobacteria represent a consistent and widespread microbial partner for corals worldwide.
