Aerobic Granular Sludge Metagenomes with 759 Assembled Genomes

759 Metagenome-Assembled Genomes (MAGs) were constructed from aerobic granular sludge cultivated under three different carbon source conditions. The dataset, PRJEB38840, includes metagenomic assemblies, MAGs, and associated metadata from samples taken between day 71 and day 740 of reactor operation. Jaspreet Singh Saini of École Polytechnique Fédérale de Lausanne compiled this collection, which was dereplicated to 331 MAGs.

Use Cases

• Comparative analysis of microbial community composition based on carbon source type (VFA, CM, CP).
• Benchmarking genome assembly and binning workflows using the two distinct methods (A and B) described.
• Studying the genomic potential of bacteria in aerobic granular sludge systems for bioremediation.
• Investigating temporal microbial dynamics in sequencing batch reactors over a 740-day period.

Strengths

• Contains 759 Metagenome-Assembled Genomes (MAGs) derived from a specific experimental setup.
• Data originates from a defined study with samples from three distinct carbon source conditions over a 740-day operational period.
• Includes associated metadata for the metagenomic assemblies and MAGs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Last update date is unknown; freshness unverified.
