Isolasi Dan Karakterisasi Bakteri Pengoksidasi Amonia Sebagai Agen Bioremediasi Di Tambak Udang Bengkalis, Riau

---

Intensive shrimp farming produces considerable inorganic nitrogenous waste—particularly ammonia, nitrite, and nitrate—which poses risks to both shrimp health and the surrounding environment. Bioremediation using ammonia-oxidizing bacteria (AOB) offers an effective strategy to reduce toxic ammonia concentrations. This study aimed to isolate and characterize AOB with bioremediation potential for shrimp aquaculture systems. Water and sediment samples were collected from two shrimp ponds—an intensive pond in Penebal Village and a super-intensive pond in Deluk Village, Bengkalis, Riau. Bacteria were isolated using selective media and screened based on their ability to convert ammonia in a nitrification medium containing 130 mg/L of total ammonia nitrogen (TAN). Ammonia oxidation was measured using Nessler’s reagent. Characterization of AOB isolates included macroscopic, microscopic, and biochemical-physiological analyses. A total of 23 bacterial isolates were obtained, confirmed as AOB based on their ammonia-oxidizing capability. These isolates displayed varied colony morphology (color, shape, margin, and texture), Gram staining results, and oxidative/fermentative profiles. All AOB isolates were catalase-positive and non-motile. Among them, isolate NS 6.1 exhibited the highest ammonia oxidation efficiency, reaching 80.07%, indicating strong potential for application as a bioremediation agent in aquaculture environments
Key findings: ammonia, ammonia-oxidizing bacteria, bioremediation, nitrite, shrimp ponds
