Diesel oil is the main source of energy used in Antarctica. Since diesel composed toxic compounds such as polycyclic aromatic hydrocarbons (PAHs) and heavy metals, it represents a constant threat to organisms inhabiting this continent. In present study, we characterized chemical biological parameters diesel-exposed soils obtained from King George Island Contaminated PAH concentrations 1000 times higher than non-exposed soils. Some contaminated soil samples also exhibited high cadmium lead. A...
Abstract Background Bacterial biosynthesis of fluorescent nanoparticles or quantum dots (QDs) has emerged as a unique mechanism for heavy metal tolerance. However, the physiological pathways governing removal QDs from bacterial cells remains elusive. This study investigates role minicells, previously identified means eliminating damaged proteins and enhancing resistance to stress. Building on our prior work, which unveiled formation minicells during cadmium in Escherichia coli , we...
Abstract Background Quantum Dots (QDs) are fluorescent nanoparticles with exceptional optical and optoelectronic properties, finding widespread utility in diverse industrial applications. Presently, chemically synthesized QDs employed solar cells, bioimaging, various technological domains. However, many applications demand prolonged lifespans under conditions of high-energy radiation. Over the past decade, microbial biosynthesis nanomaterials has emerged as a sustainable cost-effective...
In recent years, the utilization of extremophile microorganisms for synthesis metal nanoparticles, featuring enhanced properties and diverse compositions, has emerged as a sustainable strategy to generate high-quality nanomaterials with unique characteristics. Our study focuses on biosynthesis Cu-In-S (CIS) which garnered considerable attention in past decade due their low toxicity versatile applications biomedicine solar cells. Despite this interest, there is notable absence reports...
