Summary
Biofiltration effectively removes odor pollutants, with microbial diversity initially decreasing then increasing. Bacillus species dominate the biofilm, aiding in odor treatment.
Area of Science:
- Environmental microbiology
- Biotechnology
Background:
- Biofiltration is a key technology for odor control.
- Understanding microbial communities in biofilters is crucial for optimizing performance.
Purpose of the Study:
- To investigate the microbial community structure and dynamics in a biofilter treating odor pollutants.
- To correlate microbial changes with the efficiency of odor removal.
Main Methods:
- Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) was used to analyze microbial diversity.
- Scanning electron microscopy (SEM) was employed to visualize biofilm development.
Main Results:
- Odor pollutant removal efficiency increased from 50% to 89% with acclimation.
- Microbial diversity initially decreased then increased, with higher diversity observed in cortex media compared to straw.
- Bacillus species were identified as dominant bacteria (33.3%), alongside a significant proportion of uncultured bacteria (44.4%).
Conclusions:
- The microbial community in biofilters adapts to pollutants, leading to improved odor removal.
- Biofilm development and microbial diversity are essential for stable and efficient biofiltration performance.
