Quantification of the inorganic phase of the pelagic aggregates from an iron contaminated lake by means of Raman spectroscopy
TLDR
A semi-quantitative investigation of the inorganic phase of pelagic, iron-rich aggregates (iron snow, IS) formed in an iron polluted aquatic environment was performed by means of Raman spectroscopy.About:

AUTHOR'S CORRECTION pH Gradient-Induced Heterogeneity of Fe(III)-Reducing Microorganisms in Coal Mining-Associated Lake Sediments
TL;DR: In this article, the impact of pH on the Fe(III)-reducing activities in both of these sediment zones was investigated, and molecular analyses that elucidated the sediment microbial diversity were performed.

Schwertmannite: A review of its occurrence, formation, structure, stability and interactions with oxyanions
TL;DR: Schwertmannite is an enigmatic Fe(III) oxyhydroxy-sulfate mineral that is of widespread interest in the soil science, environmental geochemistry, hydrometallurgy and wastewater fields as mentioned in this paper.

TL;DR: It is suggested that microbially mediated Fe(II) oxidation dominates in the presence of DOM leading to the formation of nano-sized biogenic Fe(III) (oxyhydr)oxides that might be readily bioavailable and likely important to iron and carbon cycling.

TL;DR: Strain C25 appeared to have ecological relevance for both the formation and transformation of the pelagic iron-rich aggregates at oxic/anoxic transition zones in the acidic lignite mine lake.

Development of a hydroxyl group-mediated biosynthetic schwertmannite as a persulfate activator for efficient degradation of RhB and Cr(VI) removal.
TL;DR: In this paper, a modified schwertmannite (Sch-PVA) synthesized via the mediation of acidithiobacillus ferrooxidans in the introduction of polyvinyl alcohol (PVA).

Microbial structuring of marine ecosystems
Farooq Azam,Francesca Malfatti +1 more
TL;DR: The need to examine the biochemical interactions of microorganisms with ocean systems at the nanometre to millimetre scale is stressed — a scale that is relevant to microbial activities and must be scaled up to make useful predictions of how marine ecosystems in the whole ocean might respond to global change.

Role of large particles in the transport of elements and organic compounds through the oceanic water column
Scott W. Fowler,George A. Knauer +1 more
TL;DR: The role of large detrital particles in the downward vertical mass flux in the sea has been investigated in a variety of sources, including sediment trap data as mentioned in this paper, and it has been shown that the relatively rare, large particles sinking through the water column are responsible for the majority of the downward mass flux.

Raman spectroscopy of iron oxides and (oxy)hydroxides at low laser power and possible applications in environmental magnetic studies
TL;DR: In this article, a very low laser powers were applied to distinguish between the different iron oxides occurring in soils, and a wuestite band at about 595 cm −1 could be established enabling a non-ambiguous identification of this mineral by its Raman spectrum.
Journal ArticleDOI
Iron-Oxidizing Bacteria: An Environmental and Genomic Perspective
TL;DR: Research on lithotrophic, oxygen-dependent FeOB that grow at circumneutral pH has accelerated, driven by several factors including the recognition by both microbiologists and geoscientists of the role FeOB play in the biogeochemistry of iron and other elements.
