“…Bakteri ini mampu memanfaatkan amonium dan nitrat sebagai sumber nitrogen serta dapat menurunkan kadaramonia dalam perairan. Cara penguraian limbah, yaitu dengan cara oksidasi yaitu pemecahan senyawa kompleks menjadi sederhana (Kim et al, 2021) Pada sebuah tambak udang, limbah organik yang dihasilkan dapat berasal dari sisa pakan maupun feses hewan ternak. Limbah organik dapat meningkatkan kadar amonia yang toksik bagi biota air dengan batas tertinggi 0,1 mg/l.…”

Pollutants can cause pollution and poisoning of biotic components in a natural ecosystem in dangerous compounds such as hydrocarbons, mercury, ammonium nitrogen, and difficult-to-degrade plastics. Therefore, bioremediation is used to manage and control pollutants through bacteria. This article provides an overview of the latest information regarding bacteria as bioremediation agents and the technology's mechanisms. The method used is qualitative data breakdown by observing and drawing conclusions in the journal to examine the role of bacteria as bioremediation agents for harmful pollutants. Based on the study, bacteria have a unique metabolism to degrade inorganic and organic pollutants such as hydrocarbons (including petroleum), diesel oil, ammonia nitrogen, cellulose, starch, fat, styrofoam, chromium, and heavy metals. Furthermore, the overall environmental conditions can also help the organisms involved to accelerate the bioremediation process.

“…Traditional physicochemical methods (such as separation, landfill, flocculation, electrolysis, etc.) [ 3 , 4 ] for the treatment of waste oil are expensive and create secondary pollution problems [ 5 ]. One study showed that the degradation rate of hot pot waste oil by Klebsiella pneumoniae LZU10 was 37.7% in 48 h [ 6 ].…”

Biodegradation of Oil by a Newly Isolated Strain Acinetobacter junii WCO-9 and Its Comparative Pan-Genome Analysis

Waste oil pollution and the treatment of oily waste present a challenge, and the exploitation of microbial resources is a safe and efficient method to resolve these problems. Lipase-producing microorganisms can directly degrade waste oil and promote the degradation of oily waste and, therefore, have very significant research and application value. The isolation of efficient oil-degrading strains is of great practical significance in research into microbial remediation in oil-contaminated environments and for the enrichment of the microbial lipase resource library. In this study, Acinetobacter junii WCO-9, an efficient oil-degrading bacterium, was isolated from an oil-contaminated soil using olive oil as the sole carbon source, and its enzyme activity of ρ-nitrophenyl decanoate (ρ-NPD) decomposition was 3000 U/L. The WCO-9 strain could degrade a variety of edible oils, and its degradation capability was significantly better than that of the control strain, A junii ATCC 17908. Comparative pan-genome and lipid degradation pathway analyses indicated that A. junii isolated from the same environment shared a similar set of core genes and that the species accumulated more specific genes that facilitated resistance to environmental stresses under different environmental conditions. WCO-9 has accumulated a complete set of oil metabolism genes under a long-term oil-contamination environment, and the compact arrangement of abundant lipase and lipase chaperones has further strengthened the ability of the strain to survive in such environments. This is the main reason why WCO-9 is able to degrade oil significantly more effectively than ATCC 17908. In addition, WCO-9 possesses a specific lipase that is not found in homologous strains. In summary, A. junii WCO-9, with a complete triglyceride degradation pathway and the specific lipase gene, has great potential in environmental remediation and lipase for industry.

Treatment of wastewater has been a hotspot of research since ages. Emerging technologies and methodologies have been postulated to resolve the issue worldwide. Almost 97.2% of our earth is covered with water bodies, out of which 12,500 water bodies are situated in India. As per the statistics, nearly 70% water bodies are polluted in Southern Asia. Presence of emerging pollutants exacerbate the quality of flowing water. Amongst all possible ways, microbial bioremediation has been considered one of the most thriving methods to treat wastewater. This research will manifest about the isolation of B. subtilis from soil followed by its characterisation and action in treatment of wastewater which was collected from industry. From the study, it was concluded that B. subtilis holds the potential of degradation. Significant decrease in values of BOD and COD were achieved.
