Impact of Carbon Source Type and Dosage on Microbial Interactions and Phosphorus Release from Marine Sediments

This dataset contains chemical and microbial measurements generated during 15-day anaerobic incubations investigating how different carbon sources and concentrations affect phosphorus release from marine sediments. Treatments include multiple dosages of glucose and volatile fatty acids, with samples collected at several time points to monitor changes in dissolved phosphorus and sediment characteristics. Microbial community composition was analysed using 16S rRNA sequencing. The dataset shows that optimal carbon addition enhances phosphorus release, whereas excessive carbon stimulates microbial uptake of phosphorus and reduces its concentration in the overlying water. These data provide insights into carbon-driven microbial succession, sediment biochemical processes, and metabolic pathways relevant to phosphorus recovery.
