11. Antimicrobial materials from cellulose using environmentally friendly techniques
Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

12. Sensor-based Methods for Improved Understanding of Biological Water Treatment
Sammanfattning : .... LÄS MER
13. Microbial Community Assembly during Aerobic Granulation
Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER
14. Microbial Ecology of Granular Sludge
Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER
15. Ozonation as sewage effluent treatment : toxicological effects in adult and embryonic zebrafish, Danio rerio
Sammanfattning : Pharmaceutical residues are not efficiently removed by current sewage treatment plant (STP) technologies. This allows for the release of pharmaceutical residues into the aquatic environment. Pharmaceuticals and their metabolites are problematic because they are designed to affect biological processes in non-target aquatic species. LÄS MER
