Stimulation of leaf litter decomposition

Researchers report that exposure to ultraviolet and visible sunlight enhances subsequent microbial decomposition of leaf litter from a variety of plant species, likely by breaking down cell wall lignin and allowing microbes access to previously unavailable carbohydrates, findings that suggest that photodegradation is important for carbon turnover in a wide range of terrestrial ecosystems. - See at PNAS.org
