#Biofilms study reveals how multiple bacteria species manage to coexist
https://phys.org/news/2024-10-biofilms-reveals-multiple-bacteria-species.html

Dispersal of a dominant competitor can drive multispecies coexistence in biofilms https://www.cell.com/current-biology/abstract/S0960-9822(24)01017-0

"One species, #Pseudomonas aeruginosa, dominated over the other 2 #bacteria. But it migrated in search of greener pastures when the surface became too crowded rather than staying behind to compete. By striking out on its own, Pseudomonas allowed the whole colony of bacteria to thrive."

Andrew Jones and Joshua Prince at Duke University developed a model that replicates #PeripherySequestration in #biofilms by accounting for heterogeneity of antibiotic attachment sites and porosity.

In the image we show how the heterogeneous distribution of the different matrix elements and the #bacteria themselves act as barrier against #antibiotics (in red), hindering their effect.

A Whiff of #Taxonomy – Altiarchaeum hamiconexum

"within its #biofilm... Individual coccoid cells are rather distant from each other. Yet they are connected by thin cellular appendages... the constant structure and size of these appendages define the distance between cells. The three-dimensional reconstruction of the appendage reveals a remarkable hook structure"

Phage liquid crystalline droplets form occlusive sheaths that encapsulate and protect infectious rod-shaped #bacteria (2020) https://www.pnas.org/doi/full/10.1073/pnas.1917726117

"in #biofilms and due to the presence of #ExtracellularMatrix #polymers, Pf4 #phage particles form highly ordered yet dynamic #LiquidCrystals (tactoids) that surround the cells. Quite interestingly, these #tactoids confer on the cells an increased tolerance to #antibiotics."

"Jennifer Macalady is a #microbiologist who studies biological interactions between the limited resources that were available on #EarlyEarth: water, atmospheric gases and rocks. Her research takes her to some of the most hostile places for life on Earth, in search of the #microbial #biofilms that can survive there. Her most recent #expedition was to three lakes within Italy's #Frasassi #cave system"
