The structure of the exocellular polysaccharide from the cyanobacterium Cyanospira capsulata.

The exocellular polysaccharide produced by the cyanobacterium Cyanospira capsulata has been subjected to partial acid hydrolysis and N-deacetylation-nitrous acid deamination. The oligosaccharides released have been isolated by weak anion exchange and aqueous size exclusion chromatography, and characterized by a combination of 1D and 2D nuclear magnetic resonance spectroscopy, mass spectrometry, sugar composition and linkage analyses. The polysaccharide has an octasaccharide repeating unit with the following structure: [formula: see text]

THE INNOVATION ICT STRATEGY IN AGRI-FOOD SECTOR

Abstract: The achievement of Information Communication Technology (ICT) as a new ground for economic competition is deeply affecting the trade organization in many merchant sectors. For Italian agri-food products it is of absolute importance for Internet marketing to be undertaken and to foresee the consequent scenarios. The aim of this research is to exactly assess the opportunities and problems of the distribution circuit based on the virtual scenario, with a methodological and empirical approach, working on the analysis of experiences already begun by agri-food companies established in Italy and engaged in “business to consumer” and “business to business”. The ICT is configured as a phenomenon in a continuous and rapid evolution, which makes it necessary for companies to continually adapt to it and to the habits of web-consumers. This means that it is necessary to effectively enter the network of agri-food firms, and to strategically revise marketing methods focusing on the market place.
