BACELL meeting 2011

The BACELL meeting is anually organized by the European Bacillus community. It provides an excellent opportunity to discuss the latest research on Bacillus and related Gram-positive bacteria with colleagues from all over Europe. The meeting is accompanied by special meetings of the SYSMO and BaSysBio consortia, and these will be organized by the respective coordinators.
