1 show that bacterial populations can use non-nutritious attractants as cues for rapidly expanding through nutrient-rich areas, ensuring that plentiful nutrients are available for their future growth. In a second paper, Liu et al.2 build on this work to reveal an unanticipated rule of bacterial...
chemoattractants and repellents can interaction with receptor proteins in the cell envelope, which in turn influence the rate of tumbling when the cell is moving in a given direction Growth and Reproduction Essential requirements for growth include: supply of suitable nutrients source of energy water ...
Bacteria differ dramatically with respect to the conditions that are necessary for their optimal growth. In terms of nutritional needs, all cells require sources of carbon, nitrogen, sulfur, phosphorus, numerous inorganic salts (e.g., potassium, magnesium, sodium, calcium, and iron), and a large...
It is well-known that bacteria can support each others' growth and exchange nutrients. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, and their colleagues at the universities of Jena, Kaiserslautern, and Heidelberg, however, have now discovered a new way of how ba...
Limit the use of antibiotics, which can wipe out healthy bacteria along with problematic bacteria, to only when necessary as determined by your doctor. Exercise can also encourage the growth of a variety of gut bacteria. Having a more varied gut microbiota may promote better health and, in tur...
which mediates the secretion of effector toxins43,44,45,46. PathogenicPseudomonas aeruginosahas been shown to kill the amoebaAcanthamoeba castellaniby producing toxins mediated by the type III secretory system45,47. The opportunistic ability to compete for nutrients and fast growth together with the ab...
A short lag phase in the growth curve before the use of the less-preferred substrate is typical for diauxic growth. Inducer exclusion A mechanism of carbon catabolite repression by which the uptake or formation of the inducer of a catabolic operon is prevented in the presence of preferred ...
nutrients or away from repellents30. Bartumeus and Levin66hypothesized that individual swimming bacteria may be performing a LW due to a power-law (with a cutoff) distribution of run times67,68,69. However, several recent experimental works revealed that these bacteria essentially follow a ...
The researchers hope their work leads to a better understanding of how to provide nutrients to specific organisms in the microbiome, and lead to the development of sophisticated prebiotics that target the growth of specific beneficial bacteria. ...
