Summary
Researchers isolated Pseudomonas bacteria capable of degrading maleic acid from industrial wastewater. A specific strain, Pseudomonas stutzeri 832, efficiently oxidized high concentrations of maleic acid, retaining its activity after long-term storage.
Area of Science:
- Microbiology
- Environmental Science
- Biotechnology
Context:
- Industrial wastewater treatment
- Maleic anhydride production byproducts
- Microbial degradation of organic acids
Purpose:
- Isolate and identify bacteria capable of degrading maleic acid and its anhydrides
- Characterize the efficiency of isolated strains in maleic acid oxidation
- Assess the long-term stability of the degrading bacteria's activity
Summary:
- Bacteria from the Pseudomonas genus were isolated from active sludge in maleic anhydride industry sewage.
- A strain identified as Pseudomonas stutzeri 832 demonstrated significant maleic acid oxidation (70-90% of 12.5-25.0 g/l) within three days.
- The destructive activity of P. stutzeri 832 remained stable after five years of storage, both lyophilized and under vaseline oil.
Impact:
- Potential for bioremediation of industrial wastewater containing maleic acid
- Development of robust microbial agents for organic acid degradation
- Sustainable waste management strategies in chemical industries
