Microbial transformation of lignin
… on utilization of renewable resources throuqh microbial treatment. This work looks at the concept of lignin bioprocessing from the vantage point of a biochemical engineer. Coriolus versicolor, Phanerochaete chrysosporium and Sporotrichum pulverulentum, which being white-rot fungi are …

Microbial transformation of arsenic in Bengal floodplain
… regions, of Bangladesh to investigate microbial composition and functional diversity of arsenic metabolism genes and how this may be related to differences in arsenic dynamics within these soils. Compared to Pleistocene soils, the Holocene soils had higher concentrations of arsenic, …

Speciation and microbial transformation of chromium, arsenic and mercury in municipal landfill leachate
Transformation of heavy metals in landfill environment is currently not regulated by waste disposal guidelines. Chromium, arsenic and mercury speciation were investigated in municipal landfill leachate (MLL) to evaluate microbial transformation of the heavy metals in the landfill system. MLL is a …

Cobalamin-Enhanced Anaerobic Biotransformation of Carbon Tetrachloride
Anaerobic microbial transformation for the bioremediation of groundwaters contaminated with carbon tetrachloride (CT) is a promising alternative, but accumulation of hazardous metabolites and the inhibition of biotransformation when CT is present in the milligram per liter range has limited its …

Optical Signatures of Bioavailable and Terrigenous Dissolved Organic Matter Across Long Island Sound and Hudson River Estuaries
… the interplay between biological production, microbial transformation, and hydrologic forcing. At the microscale, laboratory incubations and cultures with benchtop optical measurements quantified the bacterial transformation of marsh material and phytoplankton-derived DOM. At a larger spatial …

Fabrication, solute transport characterization and biological application of a microfluidic gradient chamber
… and their attenuation often depends on microbial transformation. At elevated concentrations, these pollutants can be toxic, or at a minimum induce stress in microorganisms. Understanding microbial response to these stressors is key for mitigating their impact. In this study, a …

Degradation of the Insensitive Munitions Compound 3-Nitro-1,2,4-triazol-5-one (NTO) via Sequential Reducing-Oxidizing Conditions
… (ATO). However, NTO does not undergo any microbial transformation under aerobic conditions. In this study, we aimed to achieve full degradation of NTO by properly sequencing redox reactions. The transformation of NTO in soil was investigated in batch bioassays containing soil as the …

Resilience of peaty systems to low-severity wildfires in the Cairngorms
… forests, improved litter quality and microbial transformation within mineral-associated organic matter pools may enhance persistence (Chapter 3). These results align with our global meta-analysis, which shows that despite a high level of heterogeneity between studies, many peatlands …

Import and decomposition of dissolved organic carbon in pre-dams of drinking water reservoirs
… proposed as a potential process facilitating the microbial decomposition of stable allochthonous DOC within the pelagic zone. To study organic carbon cycling under different hydrological conditions, quantitative and qualitative investigations were carried out in three pre-dams of drinking water …

Organic-geochemical investigations on the mode of incorporation of a defined nonylphenol isomer and the herbicide MCPA in soil derived organo-clay complexes
… soils as both, the applied parent compound or a transformation product. Incorporation of the so called "bound residues" depends on several factors such as system characteristics (e.g. soil composition, pH-value), microbial activity and even the performed extraction method. So far, publications …
