ABSTRACT: Between pure documentary and pure fiction there are, more and more, a reasonable number of cinematic alternatives that convey a dimension of non-reality. Between the pointedly factual discourse and the irrational belief in an entirely narrative world, there intervenes an informed conviction in a truthful but nonexistent universe, in which the formal enunciation sells an image of objectivity. In a path that leads us from the forms and contents of reflexive and performative documentaries, according to Bill Nichols, and ends up in fake documentary itself, we will have the opportunity to stress the filmic construction and its inherent narrative purpose, be it a fictional story or the creator himself as character (others would say subject) of the cinematic construct. In a boomerang kind of logic, the more the objects direct us to a referent, the more they restore us a creative/authorial reference and, along with it, the narrative idea that instills it. In Woody Allen’s case, this storytelling manifests itself in the fake documentary genre, which works as if it is the reality, only to better manifest the sole reality that interests the director: that of the metacinema, or the cinema as self-referencial reality. The practical examples will be derived from the following films: Take the Money and Run (1969) e Husbands and Wives (1992).

Neste artigo procura-se entender a dúplice forma como o Estado Novo em Portugal lidou com o livro como objecto de acção política. As tentativas de enquadrar o livro como alvo de promoção no sentido de um apoio efectivo e da adopção de medidas correctivas das disfunções do mercado, próprias de uma matriz contemporânea e aberta de sistemas políticos e sociais desenvolvidos, nunca terão verdadeiramente existido durante o período autocrático. Com efeito, desde o seu começo até meados da década de 1950 o regime hesitou entre fórmulas – isoladas – de suporte à edição e à leitura, que não pôde ou não quis consolidar, e opções tendentes a conseguir arregimentar agentes do livro (sobretudo editores e autores) à nunca concretizada literatura oficial do Estado Novo, e que obedecesse aos seus pressupostos. O caminho trilhado parece ter sido, a partir de dado momento, essencialmente o da repressão ao livro, pautando o poder a sua actuação pela ausência de propostas de fomento do mercado editorial e livreiro como as que se verificaram noutros contextos nacionais, inclusive ditatoriais.

A strain of Pleurotus ostreatus was grown in tomato pomace as sole carbon source for production of laccase. The culture of P. ostreatus revealed a peak of laccase activity (147 U/L of fermentation broth) on the 4th day of culture with a specific activity of 2.8 U/mg protein. Differential chromatographic behaviour of laccase was investigated on affinity chromatographic matrices containing either urea, acetamide, ethanolamine or IDA as affinity ligands. Laccase exhibited retention on such affinity matrices and it was purified on a Sepharose 6B-BDGE-urea column with final enzyme recoveries of about 60%, specific activity of 6.0 and 18.0 U/mg protein and purification factors in the range of 14-46. It was also possible to demonstrate that metal-free laccase did not adsorb to Sepharose 6B-BDGE-urea column which suggests that adsorption of native laccase on this affinity matrix was apparently due to the specific interaction of carbonyl groups available on the matrix with the active site Cu (II) ions of laccase. The kinetic parameters (V (max), K (m) , K (cat), and K (cat)/K (m) ) of the purified enzyme for several substrates were determined as well as laccase stability and optimum pH and temperature of enzyme activity. This is the first report describing the production of laccase from P. ostreatus grown on tomato pomace and purification of this enzyme based on affinity matrix containing urea as affinity ligand.
