A sample of a microbial biofilm from the mine was ground up, DNA sequences were obtained and then the sequences were sorted into five genomes.
We here use in situ nanometre-scale techniques to investigate the structural and compositional architecture in a 3.3 billion-year (Ga) old microbial biofilm from the Barberton greenstone belt, thus documenting in situ calcification that was most likely related to anoxygenic photosynthesis.
A number of oral diseases, including periodontitis, derive from microbial biofilms and are associated with increased antimicrobial resistance.
Darwin's theory of evolution is a simple but powerful framework that explains how complexity can come from simplicity: how everything biological around us - from the microbial biofilms on your teeth to the majestic redwood trees - emerged from the very simplest of beginnings.
The paper tried to make a renewed attempt to illustrate the emergence of complexity of the biofilm community and reveal the mechanism of producing a macroscopic microbial biofilm pattern from the microscopic microbial cells' interaction.
In addition, a new formula was defined to quantify the microbial biofilm formation from the flux change through the biofilm-associated reactions.
Our results are consistent with previous reports, where the minimum inhibitory concentration of different antibiotics in different microbial biofilms were found to increase from 10 1000 fold, when compared to non-biofilm forming colonies [ 27].
The aim of this study was to characterise microbial biofilms on the inner luminal surface of extubated endotracheal tubes from ICU patients.
The aim of this study was to characterise microbial biofilms on the inner luminal surface of extubated endotracheal tubes from ICU patients using PCR and molecular profiling.
An alternative hypothesis for these findings has been presented, suggesting that pliable demineralized extracts from fossil bone more likely represents non-mineralized microbial biofilms rather than primary soft-tissues [4].
