Immobilized Microbial Catalytic Oxidation Preparation and Application of Biopolymeric Ferric Sulfate

Journal of Chemistry, 2019
A novel inorganic polymer flocculant, biopolymeric ferric sulfate (BPFS), was prepared by immobilization technology of microorganisms and by oxidation of ferrous sulfate using domestic Thiobacillus ferrooxidans (T. f) under acidic condition. T.

Current understanding of electroautotrophy and its relevance in astrobiology-related research. [PDF]

mLife
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Research and Development on Coatings and Paints for Geothermal Environments: A Review

Advanced Materials Technologies, Volume 8, Issue 18, September 25, 2023., 2023
Geothermal power production, by harnessing the natural heat in the earth's crust, provides clean energy, with year‐round availability. However, corrosion, erosion, and scaling of power plant components can hinder energy production. In his review paper, the first of its kind since 1980, a detailed overview of research studies on coatings developed to ...

Electrified bioreactors: the next power‐up for biometallurgical wastewater treatment

Microbial Biotechnology, Volume 15, Issue 3, Page 755-772, March 2022., 2022
Over the past decades, biological treatment of metallurgical wastewaters has become commonplace. Electrification of low rate biological applications has resulted in the development of bioelectrochemical systems (BES), but electrification of high rate systems has been lagging behind due to the limited mass transfer, electron transfer and biomass density

Structural and Functional Annotation and Molecular Docking Analysis of a Hypothetical Protein from Neisseria gonorrhoeae: An In‐Silico Approach

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Background. Worldwide, Neisseria gonorrhoeae‐related sexually transmitted infections (STIs) continue to be of significant public health concern. This obligate‐human pathogen has developed a number of defenses against both innate and adaptive immune responses during infection, some of which are mediated by the pathogen’s proteins.

Bioadsorptive Removal of the Pollutant Zn(II) from Wastewater by Delftia tsuruhatensis Biomass

Applied and Environmental Soil Science, Volume 2022, Issue 1, 2022., 2022
This investigation suggests the applicability of Delftia tsuruhatensis biomass for the removal of Zn(II) from the aqueous environment. Twenty‐three zinc‐resistant bacterial strains were isolated from contaminated rhizosphere soils. Selectively, the bacterium strain SA‐101 was selected as the most zinc‐resistant and identified by 16S rRNA sequencing as ...

Molybdenum Oxidation by Thiobacillus ferrooxidans [PDF]

Applied and Environmental Microbiology, 1992
Thiobacillus ferrooxidans AP19-3 oxidized molybdenum blue (Mo 5+ ) enzymatically. Molybdenum oxidase in the plasma membrane of this bacterium was purified ca. 77-fold compared with molybdenum oxidase in cell extract.

Thiobacillus ferrooxidans, a facultative hydrogen oxidizer [PDF]

Applied and Environmental Microbiology, 1990
The type strain (ATCC 23270) and two other strains of Thiobacillus ferrooxidans were able to grow by hydrogen oxidation, a feature not recognized before. When cultivated on H2, a hydrogenase was induced and the strains were less extremely acidophilic than during growth on sulfidic ores. Cells of T.
