Blue biotechnology: enhancement of bioremediation using bacterial biofilms on biodegradable scaffolds
2016
Petroleum hydrocarbons are still the most threatening environmental pollutants. A promising non invasive and low-cost technology for the treatment of contaminated sites is based on bioremediation by biodegrading microorganism endowed with catabolic ability towards oil and derivatives. New methods are needed to enhance and optimize natural biodegradation, such as the immobilization of hydrocarbons degraders in many types of supports. We developed a scaffold-bacteria bioremediation system to clean up oil contamination based on degradable 3D scaffolds. The polycaprolactone component is biodegradable, produced in the melt, i.e. at low cost and without the use of toxic solvents. The biofilm is m…
Tecnica Co.Di per la produzione di cartilagine solida umana

Abstract English Tissue or organ transplantation is severely limited by the problems of donor shortage and immune rejection from the patients. The cartilage defects are difficult to reconstruct. In head and neck surgery, as in septal reconstruction, auricular reconstruction for injury or malformation, in laryngotracheal reconstruction, surgeons harvest autologous cartilage from a donor site (of the patient) in order to reconstruct the defect. Today's current therapies to reconstruct cartilage defects involve the use of autologous cartilage grafts or biocompatible implants, but these seem inadequate to restore form and function, have many limits and are related with many complications. Due t…
