1. Isolation and characterization of novel microorganisms


Recently technological advances now allow an unprecedented access to “omic” information and a better understanding of the biology of microorganisms. Since these techniques are optimally applied when studying isolated stains, it is clear that increasing the diversity of cultured microorganisms via renewed cultivation efforts and the development of new culturing techniques to culture novel microorganisms has a great potential in the discovery of novel metabolisms, enzymes and bioactive compound. In this spirit we have developed and maintained a collection of microorganisms containing over 1500 strains from different aquatic environments. Many novel species and genomes have been (and will continue to be) described and this information will help increase our understanding of their functional role in the environment. These novel species are also prime candidates to the screening of bioactive properties and industrial exploitation. With the recent transfer of Dr Didier Stien to the LBBM we will be expanding the collection and to include endophytic fungi and bacteria.
