The ongoing COVID-19 pandemic has pushed scientists and technologists to find novel strategies develop new materials prevent the transmission, spread, entry of pathogens into human body. In this report, fabrication polyvinyl chloride (PVC)-SiO2-Ag composite is presented, in which percentage Ag 0.84% wt. Our findings render that eliminates (> 99.8%) bacteria fungus (Staphylococcus aureus, Escher...

The present findings indicate that the wide fluctuation observed in the antiviral activity of various crude helenine preparations may be attributable to the presence of varying amounts of inhibitor. Antiviral activity could be enhanced by removal of the inhibitor. A meaningful value for helenine titer in a preparation clearly should be determined in the inhibitor-free zone.

1. A cellobiohydrolase component was isolated from a Penicillium funiculosum cellulase preparation by chromatography on DEAE-Sephadex, and purified by isoelectric focusing. 2. Purified in this way, the enzyme was homogeneous as judged by electrophoresis on sodium dodecyl sulphate/polyacrylamide gels and isoelectric focusing in polyacrylamide gels. 3. Acting in isolation, the enzyme had little h...

Glucose oxidase is an important enzyme hydrolyzing for its hydrolyzing activity on glucos. It possesses and has a wide board of applications in different industries such as bakery, pharmaceutical, plant pathology and biosensors. In this study, yeast (Saccharomyces cerevisiae) was transformed successfully by the glucose oxidase gene (gox) obtained from Penicillium funicolusum. The secreted gluco...
