Metal-bearing solid wastes are an important secondary source of metals. Compared to
mining from ores, the recovery of metals, especially precious metals from rich secondary …

Bacteria in natural and artificial environments often reside in self-organized, integrated
communities known as biofilms. Biofilms are highly structured entities consisting of bacterial …

A facile one-pot eco-friendly process for synthesis of gold nanoparticles (AuNPs) with high
catalytic activity was achieved using cell-free extracts of Aspergillus sp. WL-Au as reducing …

Biomineralization is a process in which organic matter and inorganic matter combine with
each other under the regulation of living organisms. Because of the biomineralization …

With a projected steady decline of gold ore grade in mineral resources, mining applications
enabling efficient metal extraction from low-grade ores are of increasing interest to the …

In the past two decades, the use of biomolecules, either from biological or biomimetic
systems (or so-called biological or biomimetic synthesis), has emerged as a promising …

The uptake of precious metals from electronic waste is of environmental significance and
potential commercial value. A facile bioreductive synthesis is described for Au nanoparticles …

Since biofilms are an important issue in the fields of medicine and health, several recent
microbiological studies have focused on their formation and their contribution to toxic …

BACKGROUND There is currently an increase in the use of new types of fertilizers in
modern agriculture. Studies have shown that amino acid fertilizers can improve crop yield …

Fresh produce, like spinach, harbors diverse bacterial populations, including spoilage and
potentially pathogenic bacteria. This study examined the effects of produce washing in …
