The Bioremediation Process of Liquid Waste from A Fish Auction Place is Based on the Parameters of Chemical Oxygen Demand and Ammonia

Background and Objectives: The Bajomulyo fish auction place unit II, Juwana – Pati is experiencing poor sanitation due to inefficient liquid waste processing, which results in high levels of chemical oxygen demand and ammonia. Therefore, it is necessary to apply effective alternative management technology, especially bioremediation technology. The purpose of this study is the Utilization of biological agents in bioremediation technology to overcome Chemical Oxygen Demand and Ammonia.

Methods: This study used experimental methods and was carried out during August 2023 to October 2023. The best bacteria in degradation studies require a bacterial screening strategy through isolation and selection stages. then identified using molecular genetics.

Results: The degradation test findings indicated that Isolate 2 had the highest potential level. The effective chemical oxygen demand parameter dropped from 6,666.7 mg/l to 5,566.7 mg/l, whereas ammonia levels fell from 34.2 mg/l to 13.3 mg/l. Bacterial identification isolate 2 has a maximum similarity level of 99%. The identification of isolate 2 bacteria has a maximum similarity level of 99%. Based on the phylogenetic tree study, this isolate has a very close kinship with the Streptomyces heilongjiangensis strain FREP 14.

Conclusion: Indigenous bacteria may be detected in fish auction wastewater and are capable and effective decomposers of wastewater including chemical oxygen demand and ammonia.
