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.

Automated adjustment of metabolic niches enables the control of natural and engineered microbial co-cultures

|
By Blox Bloxham
| ScienceDirect Verified
Ensuring the coexistence of several microbial species in the same cultivation device would be an important technological advance, in terms of both fundamental research (e.g., understanding how species can coexist and what are the ecological drivers for this coexistence [1., 2., 3., 4.]), and applications (e.g., through the exploitation of division of labor for bioproduction [5., 6., 7.]).
