'The focus of APROPOS is to develop novel eco-efficient bio-mechanical processing solutions to enrich intermediate fractions from industrial high protein and oil-containing process residues originating from agriculture and fisheries. Enzyme-aided modification steps are developed for the intermediate fractions to obtain value-added nutritive and bio-active components, chemical as well as functional bio-materials suitable for exploitation in food, skin care, wound healing, bio-pesticide and soil improvement product applications. Mentioned residues are voluminous in Europe and globally significant. Zero waste concepts to be developed aim at avoidance of unnecessary purification of the components, establishment of local and distributed processing units in connection with the primary production and new business opportunities essentially for SMEs in Europe and beyond. An emphasis is directed to East Africa and India to support their needs to process local residues to components directed to nourish infants and fight against pests, respectively, in rural areas of both regions. The success of technological developments will be assessed in terms of economical feasibility, raw material efficiency and environmental impacts. The assessment will also include study on how the developed residue producer-end use value chain will affect the existing value chain from the residue producer to feed or energy. The multidisciplinary research group and cross-industrial SME group together cover the whole value chain from residue producers and processors to various end-users. The expertises of the partners include crop and fish processing, process hard ware manufacture, mechanical, chemical and biotechnical biomaterial processing, biomaterial up-grading and analytics, enzyme technology, end-product applications, assessment of eco-efficiency and value chains, technology transfer and commercialization. Feasibility of the developed processes is verified by demonstrations. Bio-mechanical processi'
'Biofilms are bacterial communities encased in a self-produced hydrated polymeric matrix. An important characteristic of microbial biofilms is their innate resistance to the immune system and susceptibility to antibiotics. This resistance has made microbial biofilms a common cause of medical infections, and difficult-to-treat infections caused by colonized foreign bodies.
The NOVO project aims at developing novel approaches to prevent and/or degrade biofilms on catheters elongating their usage in humans up to 10 days.
Two complementary approaches for biofilm prophylaxis will be developed:
A. Ultrasonic coating of Inorganic antibiofouling agents (process developed by partner BIU) based on a single step sonochemical process to: a) Produce metal fluorides or metal oxides (e.g. MgF2, ZnO) nanoparticles (NPs) and simultaneously b) Impregnate them as antibacterial factors on the catheters. c) Co-coating with bio-inert polymer layers (containing highly hydrophilic antifouling polyethylene glycol, zwitterionic moieties or sugar-groups) grafted onto NPs of adjusted size to the size of MgF2/ZnO NPs or directly onto MgF2/ZnO NPs; to form a hydrogel layer for the protection of the MgF2/ZnO antibiofouling activity.
B. Bio/organic antibiofouling activation: 1) Novel coating for catheters based on radical catalyzed polymers to yield anti-bacterial activity. An enzymatic reaction will be applied on the phenolic compounds to generate phenolic radicals to be further polymerized on the catheter surface as an antibiofilm agent. 2) Develop and engineer Cellobiose Dehydrogenases (CDH) that actively oxidizes and degrades biofilms polysaccharides concomitantly producing stoichiometrically H2O2 as antibacterial agent. The enzymes will be coated on the catheters via a lubricant or by the Ultrasonic (US) process after their immobilization. Some novel CDH representatives already show very low activity on glucose which should be removed by further genetic engineering.'
