Razpoložljivost neoporečne pitne vode postaja vse večja skrb v globaliziranem svetu. Kavitacija, kot nova obetajoča alternativna metoda pri procesu čiščenja vod, je pojav parnih mehurčkov v tekočinah ob hitrem lokalnem padcu tlaka, ki agresivno in hitro implodirajo, kar povzroča ekstremne fizikalno- ...

Liposomes are widely applied in research, diagnostics, medicine and in industry. In this study we show for the first time the effect of hydrodynamic cavitation on liposome stability and compare it to the effect of well described chemical, physical and mechanical treatments. Fluorescein loaded giant ...

The applications of bacterial sonolysis in industrial settings are plagued by the lack of the knowledge of the exact mechanism of action of sonication on bacterial cells, variable effectiveness of cavitation on bacteria, and inconsistent data of its efficiency. In this study we have systematically c ...

V magistrskem delu smo spremljali odziv bakterije Bacillus subtilis PS-216 na signalni peptid ComX, ki sproži odziv na kvorum (zadostno število) celic. Optimizirali smo protokol za pripravo rekombinatnega peptida ComX v bakteriji Escherichia coli ED367 in ga uspeli izboljšati tako, da smo kulturo na ...

cavitation;microbubbles;bacteria;surface cleaning;water treatment;disinfection;
Cavitation is a potentially useful phenomenon accompanied by extreme conditions, which is one of the reasons for its increased use in a variety of applications, such as surface cleaning, enhanced chemistry, and water treatment. Yet, we are still not able to answer many fundamental questions related ...

A sudden decrease in pressure triggers the formation of vapour and gas bubbles inside a liquid medium (also called cavitation). This leads to many (key) engineering problems: material loss, noise, and vibration of hydraulic machinery. On the other hand, cavitation is a potentially useful phenomenon: ...

Bacterial quorum sensing (QS) is based on signal molecules (SM), which increase in concentration with cell density. At critical SM concentration, a variety of adaptive genes sharply change their expression from basic level to maximum level. In general, this sharp transition, a hallmark of true QS, r ...

Surfactin uniquely influences lipid bilayer structure by initially inducing membrane invaginations before solubi-lization. In this study, we exposed DOPC giant vesicles to various surfactin concentrations at different tempera-tures and observed surfactin-induced membrane invaginations by using diffe ...

Anaerobic digestion in wastewater treatment plants converts its unwanted end product – waste activated sludge into biogas. Even if the process is well established, pre-treatment of the sludge can further improve its efficiency. In this study, four treatment regimes for increasing methane production ...
