protein aggregation is a problem in biotechnology. high temperature is one of the most important reasons to enhance enzyme inactivation and aggregation in industrial systems. this work focuses on the effect of tio2 and sio2 nanoparticles on refolding and reactivation of lysozyme. in the presence of tio2 and sio2 nanoparticles, after enzyme heat treatment at 98◦c for 30 min, not only aggregates ...
the lethality of pulsed ultra-violet (uv) rich light for the inactivation of pathogenic bacteria has been investigated. a low pressure xenon filled flash lamps that produced uv intensities have been used. the pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak power req...
Biofiltration of hydrophobic and recalcitrant volatile organic compounds faces challenges, the bioaerosols sourced from biofiltration might cause secondary pollution. In this study, combination ultraviolet photodegradation biotrickling filtration (UV-BTF) was designed to treat gaseous cyclohexane, UV post-treatment (post-UV) further utilized for bioaerosol emissions management. Results showed t...
This work aimed to investigate whether different microbial assemblies in flour may influence the microbiological and biochemical characteristics of traditional sourdough. To reach this purpose, members of lactic acid bacteria, enterobacteria, and yeasts were isolated from durum wheat flour. Secondly, the isolated microorganisms (Pediococcus pentosaceus, Saccharomyces cerevisiae, Pantoea agglome...
introduction: the aim of this study was to evaluate the effect of dentin on the antifungal activity of gray and white-colored mta (gmta, wmta) using a tube-dilution test. materials and methods: mta preparations were tested freshly mixed and after 24h on candida albicans (ca). the experiment was performed in 24-well culture plates. fifty wells were used and divided into four experimental groups ...
