The interest in the biomass potential of algae continues to swell. The European Society of Microalgal Biotechnology (ESMB), the German DLG e.V. (German Agricultural Society) and DLG BENELUX from the Netherlands have agreed to organize the 5th International Algae Conference, to be held 1-2 December 2011 in Berlin, Germany. The event will primarily focus on biomass potential and the various industries that can benefit from it.
