In this study, we tested a new approach to facilitate the application of white rot fungi (WRF) under non-sterile conditions, by introducing grain sorghum as carrier and sole carbon and nutrient source for WRF. To this end, Trametes versicolor was immobilized on sorghum, and its ability to remove humic acid (HA) from synthetic and real industrial wastewater was studied. HA removal was measured as colour reduction and also analysed via size exclusion chromatography (SEC). Under sterile conditions, 80% colour removal was achieved for both synthetic and real wastewater using immobilized WRF on sorghum, without adding any additional carbon or nutrient sources. Under non-sterile conditions, immobilized fungi could again remove 80% of the colour and reached a maximum of 40 U/L laccase activity. In contrast, non-immobilized fungi cultivated in non-sterile wastewater supplemented with additional nutrients, reached only 10% decolourization and maximum 5 U/L laccase activity. SEC analysis showed that bioremoval of HA by WRF was associated with degradation of HA. Finally, immobilized fungi were used to treat real wastewater, under non-sterile conditions, in a sequential batch order without renewing the immobilized fungi. Four batch feedings were conducted and 80%, 70%, 50% and 40% colour removal was achieved for each batch, respectively, over a total incubation period of 19 days.

“…A characteristic of S is its huge variability in chemical composition and consequently in its nutritive value (Mossé et al, 1988). Ramírez et al (2005) analyzed 216 samples of S and obtained a wide range for the CP content (5.2% to 11.0%), NDF (6.3% to 22.9%) and tannins (0.02% to 5.06%).…”

“…Azevedo et al (2003) analisaram diferentes híbridos de milho e verificaram que o NNP representou, em média, 2,3% do nitrogênio total. Em grãos de sorgo foram obtidos valores de NNP relativamente constantes e próximos de 5% (Mossé et al, 1988). Diferenças genéticas e ambientais entre as amostras utilizados nos estudos e a metodologia analítica empregada podem ter determinados essas variações.…”

“…Mossé et al (1988) observaram que a concentração de LIS aumentou com a concentração de proteína no grão, mas diminuiu quando os dados foram expressos em proporção da proteína bruta. Baudet et al (1986) constataram que proteínas de grãos de milho contendo nitrogênio ao redor de 1 porcento da materia seca (baixa PB) apresentaram concentração 50 e 60% maior de triptofano e lisina, respectivamente, comparados a milhos com conteúdo de nitrogênio próximo a 3 (alta PB).…”

RESUMOO experimento foi conduzido para determinar a relação entre aminoácidos e frações nitrogenadas do grão de milho (Zea mays L.) e verificar a possibilidade de utilizar tais relações para estimar o conteúdo de alguns aminoácidos. Selecionaram-se 45 amostras de diferentes híbridos de milho cultivados na região oeste do Paraná que foram agrupadas em três categorias, de acordo com o teor de proteína bruta (baixo, médio e alto). Posteriormente, retirou-se uma sub amostra aleatória dentro de cada uma das categorias anteriores, que resultou em uma sub amostra de 15 milhos, os quais foram submetidos à análise de aminoácidos e teor de nitrogênio não-protéico (NNP). O conteúdo de proteína bruta corrigida (PBc) foi obtida descontando-se a concentração de NNP dos valores de proteína bruta. A estrutura de relação entre as variáveis foi estudada por correlação de Pearson e os modelos de regressão linear ajustados pelo método dos quadrados mínimos. Os coeficientes angulares das retas dos primeiros aminoácidos limitantes para aves e suínos (lisina, metionina e treonina) foram positivos e significativos (LIS=0,1080+0,0140PB, R 2 =0,39; MET=0,1015+0,0084PB, R 2 =0,43, TRE=0,1268+0,0184*PB, R 2 =0,51). Contudo, os coeficientes de determinação das equações foram abaixo de 0,51, indicando que a PB explica apenas uma parte da variação no conteúdo de aminoácidos do grão de milho. A predição dos aminoácidos essenciais não melhorou com a utilização da PBc como variável independente. Conclui-se que não é possível estimar, com a precisão adequada, o conteúdo de aminoácidos essenciais do grão de milho, utilizando-se como variáveis independentes a proteína bruta ou a proteína bruta corrigida.Termos para indexação: Equações de regressão, formulação de rações, Zea mays, nutrição animal. ABSTRACTAn experiment was conducted to evaluate the relationship between amino acids and nitrogen fractions of corn grain (Zea mays L.) and verify whether it is possible to use such relations to estimate amino acid contents. Forty five samples of corn hybrids cultivated in West of the State of Paraná were obtained and grouped in three categories according to the level of crude protein (low, medium and high). Afterwards, a random sub-sample was taken from each of the previous categories, resulting in a sub-sample of 15 corn hybrids that were taken out and submitted to amino acid and non-protein nitrogen (NNP) analysis. The content of corrected crude protein (CCP) was obtained by reducing the NNP concentration of CP values. The relation between variables was studied by Pearson Correlation and lineal regression models adjusted by the minimum square method. The angular coefficients of the first limiting amino acids for birds and swine (lysine, methionine and threonine) were positive and significant (LYS=0.1080+0.0140CP, R 2 =0.39; MET=0.1015+0.0084CP, R 2 =0.43, THR=0.1268+0.0184CP, R 2 =0.51). However, the determination coefficients of equations were lower than 0.51, showing that CP explains only part of the variation in the amino acid content of corn grain. ...
