A new study has seen scientists use a bacterial strain to synthesise gold nanoparticles.

Published in Microbial Cell Factories, the research by experts at the Institute of Microbial Technology (IMTech) saw a novel strain of bacteria isolated from a location near an Indian gold mine.

This strain, stenotrophomonas malophilia, was incubated for eight hours, resulting in the synthesis of gold nanoparticles that were about 40 nanometres in size.

In their conclusion, the IMTech team of scientists said: "The process of synthesis of well-dispersed nanoparticles using a noble micro-organism isolated from the gold-enriched soil sample … [leads] to the development of an easy bioprocess for [the] synthesis of gold nanoparticles."

Yogesh Nangia, Nishima Wangoo, Nisha Goyal, G Shekhawat and C Raman Suri made up the team behind the study.

IMTech was founded in 1984 and specialises in research in the areas of molecular biology and microbial genetics, cell biology and immunology, protein science and engineering, and fermentation technology and applied microbiology.
