In the present work, 3D-printed wound dressings containing different amounts of Centella Asiatica extract were synthesized via dual-crosslinking method. Methacrylic anhydride modified gelatin (Gel-MA) and pectin (Pec) chosen as base material for dressings. A dual crosslinked network was formed with Gel-MA photo-crosslinking using Irgacure 2959 Pectin psychical-crosslinking Ca++ ions. Meanwhile,...

Film-forming solutions based on four types of biopolymers were prepared and their rheological properties determined. High methylated apple pectin sodium alginate used at the concentrations 1%, 1.5%, 2%, whereas soy protein isolate pork gelatin obtained 4%, 8%, 12%. The parameters determining production appropriate type packaging film or edible coating are setting time substrate, regardless its ...

The work aimed to investigate the rheological properties and gelling process of selected film-forming solutions obtained based on hydrocolloids, such as sodium alginate, highly methylated pectin, soy protein isolate with addition pumpkin purée. It was found that both concentration hydrocolloid purée affected parameters. non-linear nature flow curves demonstrated, which allowed be described usin...

Macrophomina phaseolina, phylum Ascomycota, is a phytopathogenic fungus distributed worldwide in hot dry areas. There are few studies on its secreted lipases and none on its colony radial growth rate, an indicator of fungal ability to use nutrients for growth, on media other than potato-dextrose agar. In this study, 13 M. phaseolina isolates collected in different Brazilian regions were screene...
