Metagenomic sequencing of the iron sulfide and sulfur coupled autotrophic denitrification biofilter
Iron sulfides-based autotrophic denitrification (IAD) is a promising technology for nitrate and phosphate removal from secondary wastewater due to its cost effective and low sludge production. In recent years, 16S rDNA sequencing technology has identified the important sulfur-based autotrophic denitrifier (i.e., Thiobacillus)) in SAD, PAD and PSAD systems. However, the key players involved in the nitrogen, sulfur and iron cycles have not been clearly distinguished. This study use metagenomic sequencing technology to explore the metabolic interactions of functional community in the system.
