• PilA gene regulates the formation of self-produced electrically conductive nanowires. • Strain ACL HF Δ pilA inhibits electron extraction from pure iron and 316L stainless steel. • Strain ACL HF ∆ omcS corrodes pure iron and 316L SS more than strain ACL HF Δ pilA. • e-Pili are a pivotal way of direct electron transfer by G. sulfurreducens from metal. Extracellular electron transfer (EET) plays a critical role in bioelectrochemical processes, allowing coupling between microorganisms and extracellular solid-state electrodes, metals, or other cells in energy metabolism. Previous studies have suggested a role for outer-surface c -type cytochromes in direct metal-to-microbe electron transfer by Geobacter sulfurreducens , a model electroactive bacterium. Here, we examined the possibility of other microbially produced electrical contacts by deleting the gene for PilA, the protein monomer that G. sulfurreducens assembles into electrically conductive protein nanowires (e-pili). Deleting pilA gene inhibited electron extraction from pure iron and 316L stainless steel up to 31% and 81%, respectively more than deleting the gene for the outer-surface cytochrome OmcS. This PilA-deficient phenotype, and the observation that relatively thick biofilms (21.7 μm) grew on the metal surfaces at multi-cell distances from the metal surfaces suggest that e-pili contributed significantly to microbial corrosion via direct metal-to-microbe electron transfer. These results have implications for the fundamental understanding of electron harvest via e-pili by electroactive microbes, their uses in bioenergy production, as well as in monitoring and mitigation of metal biocorrosion.

It was also the first time the women's singles Olympic gold did not go to an Asian player, and Marín was widely hailed for boosting badminton's visibility outside of Asia. Born: June 15, 1993 Occupation: Professional badminton player Throughout her badminton career, Spanish athlete Carolina Marín has set her sights higher than simply being successful in high-level competition. In the women's singles tournament at the 2016 Olympics, Marín progressed through the preliminary stage of the competition before beating Sung Ji-hyun of South Korea and defending champion Li in the knockout round. In fact, by the time of her conversation with Ganguly, Marín had already made significant progress toward that title, having won the women's singles competition at four European Championships, three World Championships, and the 2016 Olympic Games.
