Accessing nutrients as the primary benefit arising from chemotaxis
Curr Opin Microbiol. 2023 Jul 15;75:102358. doi: 10.1016/j.mib.2023.102358. Online ahead of print.ABSTRACTAbout half of the known bacterial species perform chemotaxis that gains them access to sites that are optimal for growth and survival. The motility apparatus and chemotaxis signaling pathway impose a large energetic and metabolic burden on the cell. There is almost no limit to the type of chemoeffectors that are recognized by bacterial chemoreceptors. For example, they include hormones, neurotransmitters, quorum-sensing molecules, and inorganic ions. However, the vast majority of chemoeffectors appear to be of metaboli...

Microbial interactions in theory and practice: when are measurements compatible with models?
Curr Opin Microbiol. 2023 Jul 6;75:102354. doi: 10.1016/j.mib.2023.102354. Online ahead of print.ABSTRACTMost predictive models of ecosystem dynamics are based on interactions between organisms: their influence on each other's growth and death. We review here how theoretical approaches are used to extract interaction measurements from experimental data in microbiology, particularly focusing on the generalised Lotka-Volterra (gLV) framework. Though widely used, we argue that the gLV model should be avoided for estimating interactions in batch culture - the most common, simplest and cheapest in vitro approach to culturing mi...
