In recent decades, the attention of scientists has been drawn towards nanoparticles (NPs) of metals and metalloids. Traditional methods for the manufacturing of NPs are now being extensively studied. However, disadvantages such as the use of toxic agents and high energy consumption associated with chemical and physical processes impede their continued use in various fields. In this article, we analyse the relevance of the use of living systems and their components for the development of "green" synthesis of nano-objects with exceptional properties and a wide range of applications. The use of nano-biotechnological methods for the synthesis of nanoparticles has the potential of large-scale application and high commercial potential. Bacteria are an extremely convenient target for green nanoparticle synthesis due to their variety and ability to adapt to different environmental conditions. Synthesis of nanoparticles by microorganisms can occur both intracellularly and extracellularly. It is known that individual bacteria are able to bind and concentrate dissolved metal ions and metalloids, thereby detoxifying their environment. There are various bacteria cellular components such as enzymes, proteins, peptides, pigments, which are involved in the formation of nanoparticles. Bio-intensive manufacturing of NPs is environmentally friendly and inexpensive and requires low energy consumption. Some biosynthetic NPs are used as heterogeneous catalysts for environmental restoration, exhibiting higher catalytic efficiency due to their stability and increased biocompatibility. Bacteria used as nanofactories can provide a new approach to the removal of metal or metalloid ions and the production of materials with unique properties. Although a wide range of NPs have been biosynthetic and their synthetic mechanisms have been proposed, some of these mechanisms are not known in detail. This review focuses on the synthesis and catalytic applications of NPs obtained using bacteria. Known mechanisms of bioreduction and prospects for the development of NPs for catalytic applications are discussed.

Microbe-Sb interactions remain poorly understood and the molecular mechanism of microbe-mediated Sb(V) reduction remains unclear. In the present study, we investigated the process and mechanism of Sb(V) bioreduction by Shewanella sp. CNZ-1, which was isolated from the sediment of the Bohai Strait, in the absence or presence of sulfate/sulfite/thiosulfate. Results demonstrate that Sb(V) could be reduced to Sb(III) (including Sb 2 O 3 and Sb(III)(aq) etc.) by CNZ-1 cells. Kinetic studies are carried out using the Langmuir-Freundlich dual model and Monod model and the results reveal that Sb removal by strain CNZ-1 is a fast bioadsorption (K LF , 1/n and a are 8.03, 0.0032 and 0.95, respectively; R 2 = 0.98) and slow bioreduction (R 2 = 0.95) process. Moreover, the supplementation of SO 3 2− and S 2 O 3 2− into the reaction system can lead to the formation of Sb 2 S 3 along with the reduction of SO 3 2− and S 2 O 3 2− , while SO 4 2− can't. The precipitates of Sb 2 S 3 and Sb 2 O 3 are further characterized and confirmed by SEM-EDX, XPS and XRD. In addition, global transcriptome assays reveal that genes encoding dehydrogenase, cytochrome, reductase, stress resistance protein, membrane proteins and transporters play key roles during the transformation of SO 3 2− /S 2 O 3 2− by CNZ-1 cells and subsequent RT-qPCR assays show that the genes S.CNZ.1GM004058 and S.CNZ.1GM001069 should account for the reduction of SO 3 2− and S 2 O 3 2− by the CNZ-1 strain, respectively. 1. Introduction Recently, antimony (Sb) has received much attention because of its increasing environmental concerns [1-4]. Sb is the ninth-most mined metal worldwide, and it is used in a diverse array of industries, including the manufacturing of semiconductors, lead acid automobile batteries, printing presses, ammunition, glassware, ceramics and paint pigments [1,5]. The wide use of Sb and Sb-contained compounds has

In recent years, metallic nanoparticles (NPs) have been produced by biological methods using bacteria and have been used with remarkable environmental applications. This paper emphasizes the basic aspects of microbial synthesis of metallic nanoparticles, from the selection of the strain to the settings of reaction parameters. Mechanisms involved in the microbial production of NPs are also discussed, summarizing general findings and implications in the process. There is also a section dedicated to the identification of wastes as a source of precious metals and the production of metallic NPs from waste streams containing ionic metals to give a vision of the opportunities to implement microbial synthesis as a treatment–recovery technology. Environmental applications of biogenic NPs are reviewed in detail indicating that the implementation of these nanomaterials enable the achievement of higher removal efficiencies and greater extent of transformation of recalcitrant compounds in wastewater treatment systems. Under this scenario and based on the information reviewed concluding remarks and futures perspectives are enunciated. © 2018 Society of Chemical Industry
