This seminar presents reflections on a 7 year relationship with staff of the Institute of Management Sciences in Peshawar in Khyber Pakhtunkhwa.
Professorial Lecture to be delivered by Ken Russell, Associate Dean of Aberdeen Business School.
CyanoSol aims to develop sustainable solutions for algae related problems in the aquatic environment in parallel with the exploitation of their diverse biosynthetic capabilities.
Cyanobacteria (blue-green algae) frequently form toxic blooms posing a serious risk to human and animal health.
The CyanoSol group are involved in internationally renowned research into the environmental impact and monitoring of these toxins and other problematic metabolites including taste and odour compounds. In addition the group is investigating all aspects of the natural ecology that influence their production and persistence. This work is primarily applied, with prevention and remediation being the key focus. CyanoSol pioneered both rapid, robust detection methods for cyanotoxins and treatment methods for their removal from drinking water supplies. The use of photocatalytic water treatment has been developed for use in the destruction of toxins and pathogens in water. This work is complemented by investigations into the mechanisms and optimisation of low cost biodegradation systems using aquatic bacteria. Other key areas of focus include the isolation, characterisation and development of high purity bio-active compounds from cyanobacteria through to the provision of fine bio-chemical reagents.
