Last September 22, the follow-up meeting of the European project SCILS (http://www.era-ib.net/scils), held in León, brought together European scientists from Germany, UK, Denmark or Norway involved in the research on amino acid production by Corynebacterium glutamicum. The project aims to elucidate the influence of increasing bioreactor inhomogeneities which happen in industrial-scale bioreactors, using this bacterium as workhorse.
