GENEFISHING: AN ALTERNATE METAGENOMIC APPROACH FOR CAPTURING TARGETED BACTERIAL DIVERSITY IN AN ENGINEERED RECIPIENT E. COLI STRAIN

International audience; The metagenomic approach, defined as the direct recovery and cloning of bacterial DNA from the environment in domesticated bacterial hosts has been widely used to study bacterial populations and their functional genes in numerous environments. The advantage of this approach over conventional culture based techniques is that it encompasses a wider range of bacteria by bypassing the bias of uncultivability of more than 99% of the bacteria in soil. However, in complex and rich environments such as soils, the huge level of bacterial diversity requires construction, handling and screening of several million clones in order to cover a significant proportion of bacterial ge…
