The colloidal fraction of dissolved organic matter extracted from a forest soil persists microbial decomposition

Erika Andersson, Marloes Groeneveld, Lars J. Tranvik, Anders Tunlid et autres

Abstract We have investigated the bacterial decomposition of dissolved organic matter (DOM) extracted from the organic layer of a boreal forest soil and filtered at a pore size of 0.2 µm. This DOM source has previously been extensively characterized and contains approximately …

Bacterial decomposition of dissolved organic matter: including the colloidal perspective

Erika Andersson, Lars J. Tranvik, Marloes Groeneveld, Anders Tunlid et autres

Dissolved organic matter (DOM) is a major carbon pool and considered the most bioavailable and most mobile fraction of organic matter. DOM is generally defined as the organic matter passing a filter pore size of 0.2 or 0.45 µm, and this size …

A contrast variation SANS and SAXS study of soil derived dissolved organic matter, and its interactions with hematite nanoparticles

Erika Andersson, Viktoriia Meklesh, Luigi Gentile, Ralf Schweins et autres

Soil derived dissolved organic matter (DOM) is an important component of the carbon cycle and influences numerous biogeochemical processes, including the formation of mineral-organic associations. DOM ranges in size from small organic molecules to macromolecules and colloidal aggregates. In this study we …

Generation and properties of organic colloids extracted by water from the organic horizon of a boreal forest soil

Erika Andersson, Viktoriia Meklesh, Luigi Gentile, Abhishek Bhattacharya et autres

Organic colloids are an important part of dissolved organic matter (DOM) yet many of their properties remain elusive. The main aims of this study were to assess how the colloidal properties of DOM extracted with water from an organic boreal soil horizon …

X-Ray Scattering Reveals Two Mechanisms of Cellulose Microfibril Degradation by Filamentous Fungi

Dimitrios Floudas, Luigi Gentile, Erika Andersson, Spyros G. Kanellopoulos et autres

Cellulose degradation by fungi plays a fundamental role in terrestrial carbon cycling, but the mechanisms by which fungi cope with the crystallinity of cellulose are not fully understood. We used X-ray scattering to analyze how fungi, a commercial enzyme mix, and a …

Characterization of the Colloidal Properties of Dissolved Organic Matter From Forest Soils

Viktoriia Meklesh, Luigi Gentile, Erika Andersson, Abhishek Bhattacharya et autres

Components of dissolved organic matter (DOM) span from sub-nm molecules to colloidal aggregates of several hundred nm. The colloidal fraction is important for the transport of organic matter and associated elements in the environment, and for the stability of DOM constituents with …

Effect of extraction temperature and time on the chemical and colloidal properties of dissolved organic matter

Erika Andersson, Victoriia Meklesh, Per Inge Persson, Anders Tunlid et autres

Dissolved organic matter (DOM) is ubiquitous in terrestrial and aquatic ecosystems where it serves several important functions. It plays a central role in the landscape carbon balance, connects the terrestrial and aquatic environments, and acts as a vector for both nutrients and …

Revisiting the Dissolution of Cellulose in NaOH as “Seen” by X-rays

Birte Martin-Bertelsen, Erika Andersson, Artur Hedlund, Lars Stigsson et autres

Cotton production is reaching a global limit, leading to a growing demand for bio-based textile fibers produced by other means. Textile fibers based on regenerated cellulose from wood holds great potential, but in order to produce fibers, the components need to be …

Dissolution and fibre spinning of cellulose from an ionic liquid

Erika Andersson

Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. In this master thesis, the dissolution state of …

Identification of potentially toxic compounds in complex extracts of environmental samples using gas chromatography-mass spectrometry and multivariate data analysis

Magnus Bergknut, Adam Kučera, Kristina Frech, Erika Andersson et autres

In this study, we examined 31 samples of varying chemical composition, including samples of soils from gasworks, coke production sites, and sites where wood preservatives were heavily used; ash and soot from municipal solid waste incinerators; antiskid sand; and dust from areas …
