A sulfide-oxidizing microbiota successfully enriched from aquaculture sediment.
Microbiota dominated by Vibrio, Marinobacter, Pseudomonas and Thiobacillus spp.
Sulfide-oxidizing microbiota removed sulfide at an average rate of 100 mg/(L·h).
Immobilized microbiota removed over 85% of sulfide even recycled for five times.
