Topics of the conference (orientative, but not limited to those) 

• Biodegradation and valorization of volatile compounds and air pollutants, including organic and inorganic pollutants, odours, N and S compounds 
• Bioconversion and valorization of waste gases and greenhouse gases (e.g. CH₄, CO₂, CO) to useful products 
• Syngas fermentation 
• Biogas upgrading, biogas biodesulfurisation, synthesis gas purification 

• Microbiology of biocatalysts: aerobic and anaerobic bacteria, fungi, algae 
• Bioprocess engineering: bioreactor optimization and development, applied to waste gas treatment (e.g., suspended growth bioreactors, biotrickling filters, bioscrubbers, fluidized bed bioreactors, membrane bioreactors) 
• Microbiological aspects of waste gas treatment: physiology and metabolism, new species, microbial populations in bioreactors, application of novel microbiology approaches 
• Integration of non-biological processes
