Predictable shifts in microbial species composition lead to community-wide robustness to environmental stress

|
By Jana S. Huisman, Martina Dal Bello, Jeff Gore
| Nature Verified
Abstract Environmental stress reduces species growth rates, but how it impacts microbial community function is less clear. Here we experimentally demonstrate that increasing salinity stress shifts community composition towards species with higher growth rates. This shift leads the mean community growth rate to be more robust to increasing stress than the growth of individual species.

Repulsion from slow-diffusing nutrients improves microbial chemotaxis towards moving sources

|
By Blox Bloxham, Hyunseok Lee, Jeff Gore
| Nature Verified
Abstract Chemotaxis, or the following of chemical concentration gradients, is essential for microbes to locate nutrients. However, microbes often display paradoxical behaviors, such as Escherichia coli being repelled by several amino acids. Here, we explore chemotaxis towards a moving source and demonstrate that when multiple nutrients are released from the source repulsion from certain nutrients actually improves chemotaxis towards the source.

Microbial communities demonstrate robustness in stressful environments due to predictable composition shifts

|
By Jana Sanne Huisman, Martina Dal Bello, Jeff Gore
| BioRxiv
Abstract Environmental stress reduces species growth rates, but its impact on the function of microbial communities is less clear. Here, we experimentally demonstrate that increasing salinity stress shifts community composition towards species with higher growth rates. As a result, the mean community growth rate is more robust to increasing stress than the growth of individual species.
