Última Fungal decomposition of needles in pine plantations PFB - Pesquisa Florestal Brasileira Auer, Celso Garcia; Ghizelini, Angela Michelato; Pimentel, Ida Chapaval. A literature review was performed to discuss the fungal decomposition of needle pines and impacts on commercial forest production and sustainability. Aspects as organic matter and litter degradation, associated micobiota, and factors that condition this process are discussed. Needles are principal components of residues in pine forests and their decomposition by fungi is important to nutrient turnover. Nutrients released for soil by decomposition increases forest productivity which promotes more biomass production and fixation of carbon in trees.

Ano: 2010 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/137 Tratamento biológico de efluentes de indústrias de papel após floculação e coagulação com sais de alumínio e polieletrólitos naturais BABT Reis,Edson M. dos; Nozaki,Jorge. The flocculation and sedimentation of recalcitrant organic compounds of high molecular weight using natural polyelectrolytes, extracted from the cactus Cereus peruvianus and Opuntia ficus indica, have been studied. Organic compounds of high molecular weight from effluents of paper and pulp industries are difficult for biological degradation. However, using a mixture of aluminum salts and natural polyelectrolytes, the aggregation and settling properties of recalcitrant organics were increased if compared with conventional methods of wastewater treatment using only aluminum or iron sulfate. After flocculation, sedimentation, and filtration, the effluent was submitted to biological degradation by activated sludge process. The main advantages of using a...
