Gold Digging Bacteria could be useful metal recovery aid from waste

Scientists Nathan Magarvey and his team from McMaster University in Ontario discovered a bacteria that can transform the presious toxic solution of gold into tiny gold nanoparticle. poisonous ions in toxic solutions of gold into tiny nanoparticles of gold. When the bacteria, delftia acidovorans was cultured in the presence of gold solution the researcher discovered that the bacterial colonies were covered with dark haloes of gold nanoparticle.

According to Frank Reith an environmental microbiologist from University of Adelaide in Australia believes that the molecule with which bacteria creates the particles could one day be used to collect gold from mine waste, who is also working on gold-processing bacteria but with a different bacterium, Cupriavidus metallidurans which lives in biofilms of gold nuggets. The bacteria detoxify dissolved gold by accumulating it in inert nanoparticles inside their cells.

So, these two bacterium can be a useful tool for future mining and detoxification.

Influenza A detection by MDCK cell line

The influenza A (IA) virus is the principal cause of the outbreaks of flu. A large number of laboratories participate in the worldwide surveillance of influenza virus activity and contribute to the early recognition of newly emerging epidemic strains. Differentiation between influenza A and B viruses and determination of the subtypes of influenza A virus isolates are the first steps in the characterization of influenza viruses. This analysis is traditionally done by hemagglutination inhibition (HI) tests with specific antisera raised in ferrets, chickens, or sheep. The diagnosis of Influenza A is largely clinical. Nevertheless, it is necessary to carry out some form of rapid antigenic diagnosis and the culture of respiratory samples to confirm the etiology of the respiratory disease and to determine the antigenic characteristics of the epidemic strains. Although the “gold standard” isolation technique is inoculation in embryonated hens’ eggs, the technical difficulties involved and t...
