Abstract:

The talk will ex­plore the mo­lecu­lar mech­an­ism of elec­tron ex­change between­mi­crobes and in­sol­uble ex­tra­cel­lu­lar trans­ition metal min­er­als - ‘elec­tron trans­fer at the­mi­crobe-min­eral in­ter­face’. Such pro­cesses drive the car­bon cycle and im­pact manyother crit­ical biogeo­chem­ical cycles in di­verse ter­restrial and aquatic en­vir­on­ments.The struc­ture of elec­tric­ally in­su­lated nanowires that con­duct elec­trons from in­side the­cell to min­er­al­ised metals in the ex­tra­cel­lu­lar en­vir­on­ment will be presen­ted. The­func­tion­al­ity of these wires in pro­teo­l­i­po­somes for rapid elec­tron trans­fer from an in­tra-lipo­some elec­tron pool to ex­tra­cel­lu­lar fer­ric min­er­als will be also presen­ted along­with some in­sights into how these in­su­lated nanowires are as­sembled in the cell.
