Previously we reported the biosynthesis of intracellular cadmium sulfide quantum dots (CdS QDs) at low temperatures by Antarctic strain Pseudomonas fragi GC01. Here studied role volatile sulfur compounds (VSCs) in CdS QDs P. The nanoparticles was evaluated presence sulfate, sulfite, thiosulfate, sulfide, cysteine and methionine as sole sources. Intracellular occurred with all sources tested. However, extracellular observed only cultures amended (Cys) (Met). Extracellular were characterized...
The present study examined the biosynthesis and characterization of selenium nanoparticles (SeNPs) using two contrasting endophytic selenobacteria, one Gram-positive (Bacillus sp. E5 identified as Bacillus paranthracis) Gram-negative (Enterobacter EC5.2 Enterobacter ludwigi), for further use biofortifying agents and/or other biotechnological purposes. We demonstrated that, upon regulating culture conditions selenite exposure time, both strains were suitable "cell factories" producing SeNPs...
Use of microorganisms in contaminated water remediation is one the most studied processes recent years. The recovery metal contaminants by converting them into high-value nanomaterials represents a scarcely explored topic with high potential economic impact. In this work, authors determine capacity to remove As and Cd from aqueous solutions Antarctic bacteria previously reported as capable biosynthesizing CdS fluorescent nanoparticles (NPs) at low temperatures. Bacterial characteristics...
Here, we present the draft genome sequence of
