Implication

Randomized trial evaluates DNA extraction and storage methods to enhance wastewater microbiome monitoring, suggesting improved practices for treatment system management.

Key Points

The study aims to identify optimal DNA extraction and sample storage methods for long-read sequencing of wastewater treatment systems.
Evaluated eight DNA extraction protocols across three wastewater matrices: influent, activated sludge, and anaerobic digester mixed liquor.
Assessed six sample storage strategies for their impact on DNA yield and microbial diversity.
Measured DNA integrity and yield for different protocols and storage methods.
Magnetic-bead-based DNA extraction recovered higher-molecular-weight DNA suitable for long-read metagenomics.
Flocculation was the best sample storage method for influent and activated sludge, while centrifugation was superior for anaerobic digester samples.
