Escherichia colitemplated iron oxide biomineralization under oscillation

Abstract

Iron biomineralization on Escherichia coli surface under oscillation was attempted and produced iron biominerals with acicular and banded morphology as well as photocatalytic and electrocatalytic activities.

Biomineralization in cement and concrete research

“…Microorganisms, such as bacteria [2], fungi [3], and coccolithophores [4], and macroorganisms, such as mollusks [5] and coral [6], are well known to biomineralize CaCO 3 . The biomineralization of silicon dioxide (i.e., silica) (SiO 2 ) [7][8][9][10], calcium phosphate (i.e., apatite) [11,12], magnesium hydroxide (i.e., brucite) (Mg(OH) 2 ) [13][14][15], iron oxides (e.g., hematite, magnetite) (Fe 2 O 3 ) [16,17], and aluminum oxide (i.e., alumina) (Al 2 O 3 ) [7,18,19] also occurs in a multitude of micro-and macroorganisms, such as diatoms [9], bacteria [17], mollusks [5] and other higher-level organisms [20][21][22][23].…”

Biologically Assisted One-Step Synthesis of Electrode Materials for Li-Ion Batteries

“…In these systems, fungi, yeast and bacteria [ 24 , 25 , 26 ] promote the formation of mineral–organic assemblages, organized down to the nanometer scale (size range 1–100 nm) in a structure providing better electrochemical performances than their bulk counterparts formed under abiotic conditions. All of these previous studies have explored biomineralization in planktonic cultures, i.e., with bacterial cell suspensions in aqueous media, which have produced materials organized on the single-cell bacterial scale, i.e., submicrometer scale.…”
