Next Generation High Throughput Sequencing to Assess Microbial Communities: An Application Based on Water Quality

Area of Science:

• Environmental Science
• Microbiology
• Genetics

Background:

• Traditional water quality testing methods are slow, labor-intensive, and require specialized expertise.
• Cultivation-based methods for microbial analysis have limitations in taxonomic and phylogenetic scope.
• There is a need for rapid, sensitive, and reliable water quality assessment techniques.

Purpose of the Study:

• To highlight the shift from traditional water quality assessment techniques to metagenomic approaches.
• To review the potential of next-generation sequencing (NGS) in microbial source tracking and water biomonitoring.
• To emphasize the importance of metagenomics for understanding microbial communities and human health implications.

Main Methods:

• Review of traditional cultivation-based methodologies for microbial identification.
• Exploration of high-throughput DNA sequencing and metagenomic approaches.
• Discussion of next-generation sequencing (NGS) technologies for microbial community analysis.

Main Results:

• Metagenomics provides a more comprehensive analysis of microbial genetic diversity and population structure.
• NGS technologies identify a larger proportion of microbial communities compared to traditional methods.
• Metagenomic approaches offer rapid and reliable determination of water quality.

Conclusions:

• Metagenomics and NGS represent a significant advancement over traditional water quality assessment techniques.
• These advanced methods are crucial for effective biomonitoring of water quality.
