| Project Title: | Enhanced niche colonization and competition during bacterial adaptation to a fungus |
| Project Type: | Fungal / bacterial interaction |
| Project Summary: | Bacterial-fungal interactions (BFIs) influence microbial community performance of most ecosystems and elicit specific microbial behaviors, including the stimulation of specialized metabolite production. Using a simple BFI system encompassing the Gram-positive bacterium Bacillus subtilis and the black mold fungus Aspergillus niger, we established a co-culture experimental evolution method to investigate bacterial adaptation to the presence of a fungus. In the evolving populations, B. subtilis was rapidly selected for enhanced production of the lipopeptide surfactin and accelerated surface spreading that led to an inhibition of fungal expansion and environment acidification. These phenotypes were explained by specific mutations in the DegS-DegU two-component system. In the presence of surfactin, the fungal hyphae exhibited bulged cells with delocalized secretory vesicles and RlmA-dependent cell wall stress induction. Increased surfactin production generally enhances the competitive success of the bacterium against various Aspergillus species that likely explains the primary adaption path in the presence of A. niger. |
