  2. 11. Microbial Ecology of Granular Sludge

    Author : Raquel Liebana; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

    Abstract : 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. READ MORE

  5. 13. 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. 14. Microbial mobilization and immobilization of soil nitrogen

    Author : Per Bengtson; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; growth rate; microbial activity; respiration; assimilation; immobilization; Nitrogen; mineralization;

    Abstract : Microorganisms in forest ecosystems normally recycle nitrogen (N), such that gaseous losses and leaching are limited. Mobilization of organic N, including microbial N, and immobilization of inorganic N, especially NH4+, are the quantitatively most important N transformation processes. Various factors influence their rates, e.g. READ MORE

  7. 15. Microbial strategies for deconstruction of bark components

    Author : Amanda Sörensen Ristinmaa; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extractives; fungi; microbial communities; polysaccharides; Bark; proteomics; enzymes; bacteria; yeast;

    Abstract : Bark is the outermost part of a tree, and it is a protective layer against external threats such as microorganisms and environmental stressors. Bark consists of various polymers including lignin, cellulose, hemicellulose, and it also contains a large fraction of compounds known as extractives. READ MORE
