Última Biological colonization and leaf decomposition in a subtropical stream Ecología austral Biasi,Cristiane; Cerezer,Cristina; Santos,Sandro. In small streams, aquatic community obtains energy mainly from leaves of the riparian vegetation. Processing these leaves involves physical, chemical and biological factors that may difer among leaf species. We assessed the efects of litter quality on leaf decomposition and colonization by aquatic invertebrates in a subtropical stream. Leaves from two native, highly represented tree species common in subtropical riparian areas, Ficus luschnathiana and Gasearía sylvestris, were incubated in coarse mesh bags in a stream. Bags were sampled weekly during an incubation of 28 days. The decomposition rates were higher in leaves of F. luschnathiana than in those of C. sylvestris. In the frst seven days of the experiment, leaves of F. luschnathiana lost ~60% of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Shredders; Chironomidae; Leaf-toughness; Fungal biomass.

The production of tannase by Aspergillus tamarii was studied in submerged cultures. The fungus produced an extracellular tannase after two days of growth in mineral medium containing tannic acid, gallic acid and methyl gallate as carbon source. The best result was obtained using gallic acid as inducer (20.6 U/ml). The production of enzyme was strongly repressed by the presence of glucose. Crude enzyme was optimally active at pH 5.0 and 30º C. The enzyme was stable in a large range of pH and up to the temperature of 45º C.
