# Enhancing Skin Microbiome Analysis: A Cleaner Approach
Written on
Chapter 1: Understanding the Skin Microbiome
The human skin is a bustling habitat for countless microorganisms, including bacteria, fungi, and viruses, collectively known as the dermal microbiota. These microorganisms play crucial roles in defending against harmful pathogens and aiding in the decomposition of natural waste materials.
However, the balance of this intricate ecosystem can be disrupted by skin conditions like dermatitis and acne. Consequently, there has been a growing focus on mapping and studying the human skin microbiome in recent years.
Several technical hurdles complicate this research. For instance, cultivating skin bacteria in laboratory environments presents significant challenges. Traditionally, researchers use agar plates to grow bacterial colonies for examination. Unfortunately, not all bacterial species thrive equally in these conditions, often leaving slower-growing varieties unexamined.
Section 1.1: Advances in Sequencing Technologies
To overcome these issues, scientists have recently begun employing advanced sequencing technologies to conduct skin microbiome surveys. Nevertheless, the presence of contaminating genetic material from skin cells and dead bacteria can obscure the sequencing results, hindering the clarity of the findings.
A recent study has introduced a method for "cleaning up" samples to eliminate non-target DNA, thereby isolating the genetic material of live bacteria that constitute the microbiome.
Subsection 1.1.1: Innovative Enzyme Use
Researchers from the Technical University of Munich have developed a technique utilizing an enzyme called benzonase for this cleanup process. Benzonase breaks down genetic material into small fragments, but it does not affect the genomes of live bacteria due to their protective outer cell walls.
The resulting fragments can then be mechanically separated before conducting 16S sequencing, a method used to map the genetic structure of intact bacteria.
Section 1.2: Implications for Dermatological Research
According to lead researcher Martin Köberle, “The enzyme-based selection of living skin bacteria can help us to find microbial biomarkers for certain dermatological illnesses and also to identify the bacteria that have a positive influence on the course of the disease. Perhaps they will be used in treatments one day.”
Chapter 2: The Role of the Microbiome in Skin Health
The first video titled The Microbes Upon Us: How the Cutaneous Microbiome Promotes Skin Health explores the vital functions of the skin's microbiome in maintaining overall skin health and preventing disease.
The second video titled Upgrade Your Approach to Skin: Addressing the Skin Microbiome Internally and Externally discusses innovative strategies for enhancing skin health by focusing on the microbiome from both inside and outside the body.
