Chitosan-genipin film, a sustainable methodology for wine preservation
Nunes, C; Maricato, É; Cunha, Â; Rocha, MAM; Santos, S; Ferreira, P; Silva, MA; Rodrigues, A; Amado, O; Coimbra, J; Silva, D; Moreira, A; Mendo, SA novel approach is described using chitosan-genipin films as a sustainable method for wine preservation. Films prepared from fungi and from shrimp by-products showed similar mechanical and chemical properties. In addition, shrimp derived films showed no IgE positive reaction against shellfish allergenic compounds. The chitosan-genipin films were used to produce white wines without the addition of sulphur dioxi...

Molecular characterization of a new class 3 integron in Klebsiella pneumoniae
Correia, M; Boavida, F; Grosso, F; Salgado, MJ; Lito, LM; Cristino, JM; Mendo, S; Duarte, AKlebsiella pneumoniae FFUL 22K was isolated in April 1999 from the urine of an intensive care unit patient in Portugal. The strain showed an extended-spectrum cephalosporin resistance profile. A typical synergistic effect between cefotaxime or cefepime and clavulanic acid was observed. An Escherichia coli transformant displayed a similar resistance phenotype and harbored a ca. 9.4-kb plasmid (p22K9). Cloning ex...
