Blue-green algae (AKA cyanobacteria) have a superpower which likely helps them be highly successful as invaders of waterways. They have an extraordinary ability to store energy and nitrogen in their cells for times of need. But how exactly they do so remains only partly understood.
Now researchers from McGill University and their collaborators at ETH Zurich have uncovered an intriguing hitherto unknown ability of the enzymes (known as cyanophycin synthetases) that are active in creating these food reserves. Their findings, described in a recent paper in Nature Communications, are not only scientifically surprizing, but take us a step closer to being able to use these environmentally friendly polymers for everything from bandages to biodegradable antiscalants to animal food.
