Journal ArticleDOI
Bacterial cellulose: a versatile biopolymer for wound dressing applications
TL;DR: This review assesses the BC main features and emphasis is given to a specific biomedical application: wound dressings, with particular focus on the biochemistry and genetic manipulation of BC.
Journal ArticleDOI
PET microplastics affect human gut microbiota communities during simulated gastrointestinal digestion, first evidence of plausible polymer biodegradation during human digestion
Alba Tamargo,Natalia Molinero,Julián Jiménez Reinosa,Víctor Alcolea-Rodriguez,Raquel Portela,Miguel A. Bañares,José F. Fernández,M. Victoria Moreno-Arribas +7 more
TL;DR: In this paper , a single dose of polyethylene terephthalate (PET) through the gastrointestinal tract was simulated by combining a harmonized static model and the dynamic gastrointestinal simgi model, which recreates the different regions of the digestive tract in physiological conditions.
Journal ArticleDOI
Living bacteria rheology: Population growth, aggregation patterns, and collective behavior under different shear flows
Pedro Patrício,Pedro Almeida,Raquel Portela,Rita G. Sobral,Inês R. Grilo,T. Cidade,C. R. Leal +6 more
TL;DR: Two different strains of the human pathogen Staphylococcus aureus-strain COL and its isogenic cell wall autolysis mutant, RUSAL9-were considered and their complex viscoelastic behaviors were observed to be shear-stress-dependent.
Journal ArticleDOI
Real-time rheology of actively growing bacteria
TL;DR: In this article, the population growth of a Staphylococcus aureus culture, an active colloidal system of spherical cells, was followed by rheological measurements, under steady-state and oscillatory shear flows.
Journal ArticleDOI
Role of MurT C-Terminal Domain in the Amidation of Staphylococcus aureus Peptidoglycan.
Bárbara V Gonçalves,Raquel Portela,Ricardo Lobo,Teresa A. Figueiredo,Inês R. Grilo,Ana Madalena Ludovice,Hermínia de Lencastre,Hermínia de Lencastre,Jorge S. Dias,Rita G. Sobral +9 more
TL;DR: In vivo evidence is provided of the effect of substitutions at specific residues in DUF1727 on cell wall peptidoglycan amidation and on the phenotypes of oxacillin resistance and bacterial growth.
