Making Sense of 16S rRNA Community Analysis Sequencing for Wastewater Operations

16S rRNA sequencing is a powerful technique used to identify and classify bacteria and archaea based on their genetic material. It targets the 16S ribosomal RNA gene, which is present in all prokaryotes and contains both conserved and variable regions. Common methodologies Sanger SequencingRead length is typically ~700–1,000 bp, covering the full-length 16S rRNA gene. This method is high-quality and low-throughput, making it useful for identifying single isolates or pure cultures. It is accurate and well-established but not practical for complex or mixed microbial communities. Commonly used in pure culture applications rather than community analysis (e.g., activated sludge).Next-Generation SequencingPlatforms such as Illumina
