Název v původním jazyce

Antimicrobial polyhydroxybutyrate submicron fiber mat loaded with zinc phthalocyanine derivative

Popis výsledku v původním jazyce

The aim of this work was to prepare a new biodegradable polyhydroxybutyrate (PHB) submicron fiber mat loaded with phthalocyanine (Ptc) derivative by centrifugal spinning technology, an alternative approach to fabricate nanofibers or microfibers from solutions at high speed and low cost. The results proved a significant production of singlet oxygen by the prepared photocatalytic fiber mat. In contrast with the results of other research groups published before, we have found a very significant antibacterial activity of a neutral zinc Ptc derivative, entrapped in PHB submicron fiber matrix, against Gram-negative Escherichia coli bacteria under visible light irradiation and even in the dark. On the contrary, the antibacterial effect of the photocatalytic fiber mat against Gram-positive Enterococcus faecalis was only moderate under visible light irradiation and no effect was observed in the dark.
