2. 1. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

   Author : Benoit Guieysse; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

   Abstract : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. READ MORE

4. 2. Biotechnological treatment of chlorophenol-contaminated water

   Author : Hamid Zilouei; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; Cell-based biosensor; Fluorescence in situ hybridization; Bacterial community; Two-liquid phase partitioning bioreactor; Photolysis pretreatment; Biomonitoring; Fixed-biofilm reactors; Toxic organic pollutant; Biodegradation;

   Abstract : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.

5. 3. Microbial Degradation of Toxaphene

   Author : Martha Lacayo; Avdelningen för arbets- och miljömedicin; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Enterobacter; Environmental technology; Bjerkandera; Toxaphene; Biodegradation; Biotechnology; Bioteknik;

   Abstract : This works deals with the degradation of a group of recalcitrant compounds known as toxaphene. Toxaphene is a complex mixture of chlorinated compounds including hexa- and octachlorocamphenes, hepta-, nona- and decachlorobornanes. Some components of toxaphene are very persistent while others are degraded rapidly by both abiotic and biotic processes. READ MORE

6. 4. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

   Author : Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. READ MORE

7. 5. 4-chlorophenol biodegradation by Arthrobacter chlorophenolicus A6

   Author : Karolina Nordin; Janet Jansson; Lawrence P. Wackett; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

   Abstract : A microorganism was isolated which could grow on unusually high concentrations of the toxic pollutant 4-chlorophenol. Taxonomic studies showed that the microorganism constituted a novel species within the genus Arthrobacter and it was named Arthrobacter chlorophenolicus A6. A. READ MORE
