Recently, members of the Acidophile Research Team at Bangor University carried out some bioleaching experiments which aimed to leach cobalt from the Captain sulfide ore (from New Brunswick, Canada). Sarah Smith, a geomicrobiologist at Bangor University and one of the collaborators in the COG3 project reports.
a) Mixed bacterial cultures used to inoculate the bioreactor experiments. b) A bioreactor before the addition of the culture and the ore. c) Adding the culture to the bioreactor experiment. d) The bioreactor at the end of the bioleaching experiment carried out at 45°C.”
The aim was to compare the bioleaching rates of metals (primarily cobalt) from the ore at two different temperatures. To do this, two different mixed cultures were grown up (one containing bacteria that are happy at about 30°C, and another with bugs that prefer slightly higher temperatures). The cultures were then added to the bioreactors, along with the ore, and the bugs were left to work their magic! Continue reading →
On Friday 30 September, scientists from across the Museum gathered to take part in Science Uncovered 2016, part of European Researchers’ Night.
The COG3 stand at Science Uncovered 2016
The theme for this year’s event was ‘Hidden Worlds’, which gave us the perfect opportunity to share the work we have been doing as part of the CoG3 project with members of the public. COG3 project member Rachel Norman reports from the event.
