Bioplastics from natural polymers could replace petroleum-based plastics, helping us keep nonbiodegradable plastics out of landfills and waterways. But there’s a problem: The most promising ...

Two new studies by biologists at Washington University in St. Louis highlight one potential source of game-changing materials: purple bacteria that, with a little encouragement, can act like ...

Photosynthetic purple bacteria utilise specialised pigment–protein complexes to convert light energy into chemical energy, thereby sustaining their metabolic processes and contributing to global ...

New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as ...

Experts believe early Earth hosted purple bacteria. Now the color could be a sign of hospitable worlds. It's possible that scientists could find signs of life elsewhere in the universe by trying to ...

A unique “flat” dimeric structure of bacterial photosynthetic reaction centre-light harvesting membrane complexes discovered by state-of-the-art cryogenic electron microscopy. Researchers at the ...

In a world overrun by petroleum-based plastics, scientists are searching for alternatives that are more sustainable, more biodegradable and far less toxic to the environment. Two new studies by ...
