Although the precipitation of carbonate minerals induced by various bacteria is widely studied, changes in biochemical parameters, and their significant role biomineralization processes, still need further exploration. In this study, Mucilaginibacter gossypii HFF1 was isolated, identified, used to induce at Mg/Ca ratios. The parameters were determined order explore mechanisms, including cell co...

Microorganisms play critical roles in the various aquatic systems forming microbial mats. The microbial mats are held together and bound to their substrates by slimy extracellular polymeric substances (EPS) having various applications which they secrete. They use all types of metabolism and feeding strategy that have evolved on Earth, and have shown immense use in various industrial application...

Abstract Many corrosion problems are caused by the presence of microorganisms, so-called microbiologically influenced (MIC). A major representative MIC-causing bacteria includes group sulfate-reducing (SRB), which accumulate in biofilms on surface. Removal biofilm inhabiting is much more complex compared to planktonic cell removal, particular, based formation an extracellular polymeric substanc...

Introduction The reduced susceptibility of biofilms to disinfectants presents a challenge the successful reprocessing medical equipment. This study examined effect residual biomass remaining after previous disinfection with peracetic acid (PAA) on tolerance subsequent mature Pseudomonas aeruginosa PAA. enzymatic degradation specific components extracellular polymeric substance (EPS) P. biofilm ...

This study discovered that biofilm extracellular polymeric substances (EPS) are biodegradable by their own producers and by other microorganisms when they are starved. The study was performed in a comparative fashion to examine the biodegradability of biofilm EPS by the microorganisms from the original biofilm (its own producers) and from activated sludge (other microorganisms). Four distinctiv...

extracellular polymeric substances are defined as high molecular weight compounds secreted by the microorganisms in the surrounding area. since these extracellular substances are mainly polysaccharide, they are named exopolysaccharide. microbial exopolysaccharides composed of sugar residue have growing interest as a new class of microbial products which can be used in food, pharmaceutical, and ...

The study presents the evaluation of the controlled release kinetics for an active pharmaceutical substance BPMDMDHI–(2-[(1-benzyl-4-piperidyl) methyl]-5, 6-dimethoxy-2, 3-dihydroinden-1-one), physically incorporated in the PVA polymeric matrix and used under a patch form. The substance presents more polymorphic forms. Our study was made for two different polymorphs of BPMDMDHI (donepezil): A a...

The application of a bacterial extracellular polymeric substance (EPS) in the bioremediation of heavy metals (Cd, Zn and Cu) by a microbial consortium in a hydrocarbon co-contaminated aqueous system was studied. At the low concentrations used in this work (1.00 ppm of each metal), it was not observed an inhibitory effect on the cellular growing. In the other hand, the application of the EPS lea...
