Orange is new ‘block’
Photosynthetic organisms tap light for fuel, but sometimes there’s too much of a good thing.
New research from Washington University in St. Louis reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae – including key features that both collect energy and block excess light absorption. The study, published Jan. 6 in Science Advances, yields insights relevant to future energy applications.
Scientists built a model of the large protein complex called phycobilisome that collects and transmits light energy. Phycobilisomes allow cyanobacteria to take advantage of different wavelengths of light than other photosynthetic organisms, such as green plants on dry land. ....
