"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.

#Vibrio Colonization Is Highly Dynamic in Early #Microplastic-Associated #Biofilms as Well as on Field-Collected #Microplastics

by Katharina Keys, et al, December 2020

Abstract:

"Microplastics are ubiquitous in aquatic ecosystems and provide a habitat for biofilm-forming bacteria. The genus Vibrio, which includes potential #pathogens, was detected irregularly on microplastics. Since then, the potential of microplastics to enrich (and serve as a vector for) Vibrio has been widely discussed. We investigated Vibrio abundance and operational taxonomic unit (OTU) composition on polyethylene and polystyrene within the first 10 h of colonization during an in situ incubation experiment, along with those found on particles collected from the Baltic Sea. We used 16S rRNA gene amplicon sequencing and co-occurrence networks to elaborate the role of Vibrio within biofilms. Colonization of plastics with Vibrio was detectable after one hour of incubation; however, Vibrio numbers and composition were very dynamic, with a more stable population at the site with highest nutrients and lowest salinity. Likewise, Vibrio abundances on field-collected particles were variable but correlated with proximity to major cities. Vibrio was poorly connected within biofilm networks. Taken together, this indicates that Vibrio is an early colonizer of plastics, but that the process is undirected and independent of the specific surface. Still, higher nutrients could enhance a faster establishment of Vibrio populations. These parameters should be considered when planning studies investigating Vibrio on microplastics."
