Abstract:
... Bacterial genome reduction is a common phenomenon in nature that has also inspired several projects with biotechnologically relevant organisms. In many cases, however, no performance improvements with the streamlined chassis were obtained. A comparative analysis of natural and synthetic reduced genomes and their corresponding ecological niches reveals that: (i) deleting expressed genes can lead to ...
