Multiple presentations from the Banta Lab were given at the 2024 American Institute of Chemical Engineers Annual Meeting which was held in San Diego, CA.  Farid Khoury gave an oral presentation entitled "Engineering of the RTX domain using phage-assisted continuous evolution (PACE) for Biomolecular recognition for application in affinity chromatography".  Zihang Su gave a oral presentation entitled "Biomimetic platform to explore conductive outer membrane proteins from acidophilic biomining bacteria".  And Farid Khoury presented a poster entitled "Protein-based

Professor Banta gave a seminar entitled “Biotechnology for critical materials production” in the Department of Chemical and Biological Engineering at Princeton University, Princeton, NJ.

A new manuscript by Jung, Inaba, and Banta describes the use of CRISPR interference in Acidithiobacillus ferrooxidans to manipulate the flow of electrons that result from iron or sulfur oxidation.  Knockdown of the petB2 gene  enhanced iron oxidation which led to enhanced pyrite and chalcopyrite oxidation.  These results demonstrate how synthetic biology can be used to create cell lines with enhanced biomining potential.  The new results were published in the Journal of Biological Chemistry.
