Renewable and sustainable biobased materials: An assessment on biofibers, biofilms, biopolymers and biocomposites
Biofibers Biopolymers Biofilms Bio composite
2024/2/5
The current global scenario has a great impact on the development of new bio-based materials due to its vital advantages that are helpful in replacing synthetic and hazardous materials. This perspecti...
By some estimates, bacterial strains resistant to antibiotics -– so-called superbugs – will cause more deaths than cancer by 2050.Colorado State University biomedical and chemistry researchers are usi...
Effects of ampicillin and vancomycin on Staphylococcus aureus biofilms
Staphylococcus aureus strain planktonic cells ampicillin vancomycin
2014/7/10
The collection of 23 coagulase-positive Staphylococcus aureus strains isolated mainly from food in the Czech Republic were tested on the ability to form biofilms in the presence of ampicillin and vanc...

Estrogens Biofilms Temperature Biodegradation BAC Columns
2013/3/19
In order to obtain information on the biodegradation potential of biofilms involved in the removal of natural estrogens by biological activated carbon (BAC) columns, batch degradation of estrone (E1) ...
Antibiotic Treatment of Pseudomonas aeruginosa Biofilms Stimulates Expression of mgtE, a Virulence Modulator
Pseudomonas aeruginosa Biofilm CFBE cell AlgR mgtE co-culture virulence
2015/5/22
Pseudomonas aeruginosa is a gram negative opportunistic pathogen with the capacity to cause serious disease by forming biofilms, most notably in the lungs of cystic fibrosis (CF) patients. Biofilms ar...

2014/2/25
This study evaluated the susceptibility of planktonic and biofilm cells of Staphylococcus spp. (n = 87), Klebsiella spp. (n = 30), and Escherichia coli (n = 74) isolates originating from food contact ...
Morphological and Structural Characteristics of Zein Biofilms with Added Xanthan Gum
zein biofilms xanthan gum morphological properties structural properties
2010/8/11
Morphological and structural characteristics of zein-based biofilms have been studied in this work. The sorbitan component in the control formulation of the film was substituted with xanthan gum at co...
Resistance of Listeria monocytogenes biofilms to disinfectants 326
Listeria monocytogenes biofilm disinfectants
2014/2/27
We studied the optimal conditions for the biofilm development by Listeria monocytogenes on a model system represented by microtiter plates, and also for determined some effective disinfectant agents. ...
Isolation and purification of total RNA from Streptococcus mutans in suspension cultures and biofilms
Dental plaque Streptococcus mutans Polymerase chain reaction RNA Polysaccharides
2009/10/16
The presence of extracellular polysaccharides matrix makes extraction and purification of RNA from Streptococcus mutans within biofilms challenging. In this study, several approaches to purify RNA ext...
Antimicrobial agents used in the control of periodontal biofilms:effective adjuncts to mechanical plaque control?
Dental plaque Gingivitis Oils essential Triclosan
