“…Likewise, exposed to Cu(II) for 10 min, no Pd(0) NPs were synthesized by Desulfovibrio desulfuricans incubated in a medium with Pd(II) [27] . However, MR‐1 can survive in environments containing a certain concentration of Cu(II) and Ag(I), and produce corresponding NPs [30,34,36] . The growth of MR‐1 cultured in 30 mM 3‐(N‐morpholino)propanesulfonic acid buffer containing 0.01 mM Cu(II) was 100 % compared to the buffer without Cu(II), while the growth decreased to 20 % when Cu(II) increased to 0.10 mM [30] .…”

The biosynthesis of metallic nanomaterials, especially noble metal nanomaterials, has attracted extensive attention due to the multifarious potential applications of these materials. In this study we have explored the effects of Cu(II) on Pd(II) removal, and of Cu(II) as well as phosphate on the morphologies and composition of biogenic nanoparticles (NPs) from aqueous Pd (II) systems by Shewanella oneidensis MR-1 (MR-1). Cu(II) causes a slight efficiency decrease of Pd(II) removal by MR-1, but a high removal efficiency of 89.8 % is still achieved, which contrasts sharply with the significant Cu(II) inhibition to other microbes. Without phosphate buffer in the medium, 5-nm PdNPs densely envelop MR-1 and accumulate significantly in the periplasm in the absence of Cu(II), while 4-nm PdNPs are evenly distributed in the periplasm, and the cellular surface is smooth in the presence of Cu(II). The following effect of Cu(II) on PdNP synthesis by MR-1 is therefore proposed: Cu(II) significantly affects PdNPs morphologies by inhibiting Pd(0) transfer across the outer membrane and PdNP crystal growth in the periplasm, but not the sorption of Pd(II). Phosphate addition only slightly increases Pd harvest but also precipitates Cu(II) and poses difficulties for the biosynthesis. The study highlights the effect of co-existing metals during the biosynthesis of metallic nanomaterials and offers new insight into the mechanism of PdNP formation and the electron transfer during Pd(II) reduction by MR-1.

“…The biogenic S 2− produced by S. oneidensis MR-1 has also been applied to synthesize Ag 2 S nanospheres with a mean diameter of 9 ± 3.5 nm [ 150 ]. The produced biogenic Ag 2 S-NPs showed high biocompatibility without inhibition and cytotoxicity to both prokaryotic bacteria and eukaryotic cell lines, which was primarily attributed to the formed protein/peptide coating on the surfaces of biogenic nanoparticles during the biotransformation process [ 150 , 151 ]. Small-sized and homogenous-shaped CuS-NPs produced by S. oneidensis MR-1 were reported as a candidate for photothermal therapy, which displayed a high photothermal conversion efficiency of 27.2% because of their strong absorption under infrared light [ 152 ].…”

Bacterial extracellular electron transfer: a powerful route to the green biosynthesis of inorganic nanomaterials for multifunctional applications

et al. 2021

Synthesis of inorganic nanomaterials such as metal nanoparticles (MNPs) using various biological entities as smart nanofactories has emerged as one of the foremost scientific endeavors in recent years. The biosynthesis process is environmentally friendly, cost-effective and easy to be scaled up, and can also bring neat features to products such as high dispersity and biocompatibility. However, the biomanufacturing of inorganic nanomaterials is still at the trial-and-error stage due to the lack of understanding for underlying mechanism. Dissimilatory metal reduction bacteria, especially Shewanella and Geobacter species, possess peculiar extracellular electron transfer (EET) features, through which the bacteria can pump electrons out of their cells to drive extracellular reduction reactions, and have thus exhibited distinct advantages in controllable and tailorable fabrication of inorganic nanomaterials including MNPs and graphene. Our aim is to present a critical review of recent state-of-the-art advances in inorganic biosynthesis methodologies based on bacterial EET using Shewanella and Geobacter species as typical strains. We begin with a brief introduction about bacterial EET mechanism, followed by reviewing key examples from literatures that exemplify the powerful activities of EET-enabled biosynthesis routes towards the production of a series of inorganic nanomaterials and place a special emphasis on rationally tailoring the structures and properties of products through the fine control of EET pathways. The application prospects of biogenic nanomaterials are then highlighted in multiple fields of (bio-) energy conversion, remediation of organic pollutants and toxic metals, and biomedicine. A summary and outlook are given with discussion on challenges of bio-manufacturing with well-defined controllability.

“…17 Furthermore, the exceptionally low solubility constant of Ag 2 S CQDs (K SP = 6.3 × 10 −50 ) prevents the release of Ag + ions, rendering them well-suited for in vivo applications. 24,25 Various synthetic strategies have been developed to prepare high-quality Ag 2 S CQDs; however, the size distribution of Ag 2 S CQDs is still much broader compared with that of traditional Cd-or Pb-based CQDs. 26 The low lattice energy of Ag 2 S CQDs promotes their coalescence easily, which decreases their colloidal stability.…”
