Biofilms pose important economic and health risks in biomedical applications food industries. In this study, coatings that reduce the biofilm formation of Pseudomonas aeruginosa on polystyrene cell culture plates are deposited by plasma polymerization (3-aminopropyl)triethoxysilane using an atmospheric pressure jet system at three different power levels. Surface characterizations quantification...

Extracellular polymeric substances (EPSs) can be defined as renewable, high molecular weight materials produced by bacteria and microorganisms. EPSs are composed of primarily polysaccharides, proteins with minor amounts nucleic acids, lipids, humic substances. Cyanobacterial have a significant physiological effect on bloom formation stress tolerance in adverse conditions. Therefore, cyanobacter...

A new acid soluble extracellular polymeric substance (acid soluble EPS) was extracted from an acetate fed aerobic granular sludge reactor operated at 35 °C. Acid soluble EPS dominated granules exhibited a remarkable and distinctive tangled tubular morphology. These granules are dominated by Defluviicoccus Cluster II organisms. Acetic acid instead of the usually required alkaline extraction medi...

The objective of this research was to study phenol degradation in anaerobic fluidized bed reactors (AFBR) packed with polymeric particulate supports (polystyrene PS, polyethylene terephthalate – PET, and polyvinyl chloride PVC). The reactors were operated with a hydraulic retention time (HRT) of 24 h. The influent phenol concentration in the AFBR varied from 100 to 400 mg L, resulting in phenol...

A variety of Mg-, Na- and Ca-sulfates, including gypsum, Mg-clays precipitate within the microbial mats that developed seasonally in hypersaline playa lake El Longar (Central Spain). multidisciplinary study along a transect demonstrates degree lithification increases from soft poorly lithified layers lying on submerged ground to highly crystalline present desiccated fringes. The community compo...
