Magnetite dissolution in siliceous sediments

, 2003
Magnetite dissolution, and consequent loss of magnetization, is widely observed in reducing sedimentary environments, where the decrease in Eh-pH values with depth is driven by bacterially mediated degradation of organic carbon.

Proteomic analysis of Trichoderma harzianum secretome and their role in the biosynthesis of zinc/iron oxide nanoparticles

Scientific Reports
The fungal green synthesis of nanoparticles (NPs) has gained great interest since it is a cost-effective and easy handling method. The process is simple because fungi secrete metabolites and proteins capable of reducing metal salts in aqueous solution ...

Mineral transformation associated with the microbial reduction of magnetite

, 2000
Although dissimilatory iron reducing bacteria (DIRB) are capable of reducing a number of metals in oxides and soluble forms, the factors controlling the raterextent of magnetite reduction and the nature of the mineral products resulting from magnetite ...

Looking for biogenic magnetite in brain ferritin using NMR relaxometry

Mammalian cellular iron is stored inside the multisubunit protein ferritin. normally taking the structure of a ferrihydrite-like mineral core. It has been suggested that biogenic magnetite, which has been detected in the brain and may be related to ...

Scale-up and Optimization of Biogenic Magnetite Production

, 2012
Interest in biogenic magnetite nanoparticles is increasing as their potential applications are better understood. Magnetite can be produced by anaerobic Fe(III)-reducing and Fe(II)-oxidising bacteria. In this project the dissimilatory Fe(III)-reducing ability of G.
