16S rRNA Sequencing from Biogas Reactors Fed Marine Aquaculture Sludge

16S rRNA gene sequencing data from lab-scale biogas reactors fed a mix of cow manure and marine aquaculture sludge. The dataset includes chemical composition measurements for substrates and inoculum, heavy metal analysis, and ionic composition data. The data was collected by Linn Solli and published on figshare in April 2026.

Use Cases

• Analyze microbial community shifts based on the gradual increase of marine aquaculture sludge from 20% to 100%.
• Correlate reactor performance with chemical parameters like volatile fatty acids (VFA), total ammonium (tot-NH4+), and FOS/TAC ratios.
• Study the impact of effluent recirculation by comparing data from reactor R1 (with recirculation) and reactor R2 (without).
• Assess potential inhibitory effects based on heavy metal content measured in the marine aquaculture sludge.

Strengths

• Includes detailed chemical composition data for inoculum, cow manure, and marine aquaculture sludge, covering pH, dry matter, volatile solids, nitrogen, phosphorus, and volatile fatty acids.
• Provides heavy metal analysis and ionic composition data for the substrates, which are critical for assessing reactor stability.
• Data originates from a controlled lab-scale experiment with two continuously stirred tank reactors (CSTRs) operated over 310 days.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description is detailed but the actual data files (TXT, GZ, FA) require inspection to understand structure.
