Remediation of cadmium-tolerant bacteria combined with plant absorption on soil heavy metal cadmium pollution

浙江大学学报. 农业与生命科学版, 2017
Heavy metal contaminants enter the environment through various means, causing heavy metal pollution in the soil, especially heavy metals in farmland soils, which are becoming increasingly serious.

Active Microbial Sulfur Disproportionation in the Mesoproterozoic [PDF]

Science, 2005
The environmental expression of sulfur compound disproportionation has been placed between 640 and 1050 million years ago (Ma) and linked to increases in atmospheric oxygen. These arguments have their basis in temporal changes in the magnitude of 34 S/ 32 S fractionations between sulfate and ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Hydrogen utilization potential in subsurface sediments

Frontiers in Microbiology, 2016
Subsurface microbial communities undertake many terminal electron-accepting processes, often simultaneously. Using a tritium-based assay, we measured the potential hydrogen oxidation catalyzed by hydrogenase enzymes in several subsurface sedimentary ...

High-severity wildfire leads to multi-decadal impacts on soil biogeochemistry in mixed-conifer forests. [PDF]

, 2020
During the past century, systematic wildfire suppression has decreased fire frequency and increased fire severity in the western United States of America.

Microbial Ecology of Activated Sludge [PDF]

Applied Microbiology, 1964
Over 300 bacterial strains were isolated from seven samples of activated sludge by plating on sewage agar. Gram-negative bacteria of the genera Zoogloea and Comamonas predominated. Many isolates (51%) showed sudanophilic inclusions of poly-β-hydroxybutyric acid, whereas 34% accumulated ...

Experimental evidence that microbial activity lowers the albedo of glaciers

, 2016
doi: 10.7185/geochemlet.1611 Darkening of glacier and ice sheet surfaces is an important positive feedback to increasing global temperatures. Deposition of impurities on glaciers is primarily believed to reduce surface albedo, resulting in greater melt ...
