Bioavailability of soil organic carbon and Fe as influenced by forestry practices in a subtropical coastal catchment [PDF]

open access: yes, 2010
Potential impacts of plantation forestry practices on soil organic carbon and Fe available to microorganisms were investigated in a subtropical coastal catchment. The impacts of harvesting or replanting were largely limited to the soil top layer (0–10 cm

Microbial diversity in Baltic Sea sediments [PDF]

open access: yes, 2007
This thesis focuses on microbial community structures and their functions in Baltic Sea sediments. First we investigated the distribution of archaea and bacteria in Baltic Sea sediments along a eutrophication gradient.

Sulfidogenic activity of Desulfuromusa sp. SV30 under the influence of chromium, copper and iron compounds

open access: yesБіологічні студії, 2017
Coal pit waste heap is an example of the multifactorial stress influence on organisms. The effect of heavy metals on the cell is the most toxic. Factor analysis of data for 29 variables, defined for gangues from coal pit waste heaps, was conducted.

The compositional and evolutionary logic of metabolism

open access: yes, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...

Electron Transfer in the Biogeochemical Sulfur Cycle

open access: yesLife
Microorganisms are key players in the global biogeochemical sulfur cycle. Among them, some have garnered particular attention due to their electrical activity and ability to perform extracellular electron transfer.

Ecology of Thioploca spp.: Nitrate and sulfur storage in relation to chemical microgradients and influence of Thioploca spp. on the sedimentary nitrogen cycle

open access: yes, 2001
Microsensors, including a recently developed NO3 − biosensor, were applied to measure O2 and NO3 − profiles in marine sediments from the upwelling area off central Chile and to investigate the influence of Thioploca spp.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

open access: yes, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Solar-driven carbon dioxide fixation using photosynthetic semiconductor bio-hybrids. [PDF]

open access: yes, 2019
Solar-driven conversion of carbon dioxide to value-added carbon products is an ambitious objective of ongoing research efforts. However, high overpotential, low selectivity and poor CO2 mass transfer plague purely inorganic electrocatalysts.

Bioprocessing of ores: Application to space resources [PDF]

open access: yes
The role of microorganisms in the oxidation and leaching of various ores (especially those of copper, iron, and uranium) is well known. This role is increasingly being applied by the mining, metallurgy, and sewage industries in the bioconcentration of ...
