We reveal how substrate concentration and complexity shape microbial growth and interactions.
We also find data to support our model: we performed a systematic literature search, which shows that generalists (producing both enzymes) dominate among chitin-degrading microbes. 5/6

Finally, we explored whether microbes can divide labor in the production of these two enzymes within consortia.
Our analysis paints a fascinating picture: interactions between endo- and exo-enzyme producers can flip from positive to negative depending on substrate levels! 4/6

We have found that producers:

1. Of exo-enzymes thrive when many polymer chains are around.

2. Of endo-enzymes unexpectedly excel only when fewer chains are present.

3. Of both enzymes together expand their niche and may benefit from enzyme synergy. 3/6

Excited to share our latest paper in PLOSCompBiol @plos.bsky.social !

Our study dives into the comparison of possible extracellular polysaccharide degradation strategies and their impact on microbial growth and community dynamics. 1/6
