FLORENCE, Ala.-University of North Alabama professor Dr. Eric Becraft is receiving recognition for a recent paper he helped co-author for Nature Communications.

Nature Communications is an open access journal that publishes high-quality research in biology, health, physics, chemistry, earth sciences and other related disciplines.

Becraft, who is an assistant professor of Biology at UNA, and his team of co-authors, discovered that the ancestor of Cyanobacteria and oxygenic photosynthesis may have been an anaerobe in which fermentation and H2 (hydrogen) metabolism were central metabolic features.

Photosynthesis is the process that plants use to convert light energy into chemical energy. Chloroplasts are the areas of the plant where photosynthesis takes place. Chloroplasts in plants, hence oxygenic photosynthesis, originated from Cyanobacteria.

Cyanobacteria are a type of bacteria that obtain energy through photosynthesis and are the only type able to produce oxygen. Additionally, the evolution of aerobic respiration was likely linked to the origins of oxygenic (oxygen producing) Cyanobacteria.
