The Impact of Dissolved Organic Matter on Arsenic Mobilization from Goethite in the Presence of Silicic Acid and Phosphate under Reducing Conditions by Adeleh Aftabtalab, Eduardo Moreno-Jiménez, Jonas Henschel, Sascha Nowak, Jörg Schaller, Klaus-Holger Knorr

“…The availability of DOM in the co-presence of H₄SiO₄ and PO₄ increased the microbial activity in the system by providing more substrates for microbial metabolism, which also decreased the redox potential (reducing conditions) and consumed acidity, causing the pH to increase from 4 to 6.8. …”

Dynamic of active microbial diversity in rhizosphere sediments of halophytes used for bioremediation of earthen shrimp ponds by Marie Colette, Linda Guentas, Luc Della Patrona, Dominique Ansquer, Nolwenn Callac

“…Halophytes species seemed to promote putative microbial metabolism activities in the sediment. Taxa related to nitrogen removal, carbon mineralisation, sulphur reduction and sulphide oxidation were significant biomarkers in sediment harbouring halophytes and may be relevant for bioremediation. …”

Calcium Carbonate Hexahydrate (Ikaite): History of Mineral Formation as Recorded by Stable Isotopes by Michael J. Whiticar, Erwin Suess, Gerold Wefer, Peter J. Müller

“…In addition to the in situ temperature and pressure, nucleation of the ikaite crystals in the Bransfield Basin sediments may be induced by the high alkalinity, high phosphate concentrations, and dissolved organic compounds. Intense microbial metabolism generates such compounds; of these, aspartic acid and glutamic acid may play an important role, as they do in biological and extracellular carbonate mineral precipitation. …”

Genomic analyses of Burkholderia respiratory isolates indicates two evolutionarily distinct B. anthina clades by Amy Pham, Amy Pham, James G. Volmer, Daniel C. Chambers, Daniel C. Chambers, Daniel J. Smith, Daniel J. Smith, David W. Reid, David W. Reid, David W. Reid, Lucy Burr, Lucy Burr, Timothy J. Wells, Timothy J. Wells

“…Core- and pan-genome analyses demonstrated substantial metabolic diversity, with B. anthina Clade I enriched in genes associated with microbial metabolism in diverse environments, including degradation of aromatic compounds and metabolism of xenobiotics, while B. anthina Clade II demonstrated an enhanced capability for siderophore biosynthesis.DiscussionBased on our phylogenetic and comparative genomic analyses, we suggest stratifying B. anthina to recognise a distinct species harbouring increased potential for iron metabolism via siderophore synthesis, for which we propose the name Burkholderia anthinoferum (sp. nov.).…”

Analysis of the intestinal microbiota using SOLiD 16SrRNA gene sequencing and SOLiD shotgun sequencing by Mitra, Suparna, Förster-Fromme, Karin, Damms-Machado, Antje, Scheurenbrand, Tim, Biskup, Saskia, Huson, Daniel H., Bischoff, Stephan C.

“…Additionally, from the same fecal sample, complete genomic microbial DNA was extracted and shotgun sequenced using SOLiD sequencing to study the composition of the intestinal microbiota and the existing microbial metabolism. We found that the microbiota composition of 16S rRNA gene sequences obtained using Sanger, 454 and SOLiD sequencing provide results comparable to the result based on shotgun sequencing. …”
