1. Determinação do teor de lignina em amostras de gramíneas ao longo do crescimento através de três métodos analíticos e implicações com as equações de ″Cornell Net Carboydrate and Protein System″ / Grasses lignin content determination along their growth period through three analytical methods and implications with the Cornell Net Carbohydrate and Protein System equations
Quantificou-se o teor de lignina em cinco amostras de plantas forrageiras, nas frações caule e folha, em quatro estádios de maturidade, através de três métodos analíticos: lignina detergente ácido (LDA), lignina permanganato de potássio (LPer) e lignina Klason (LK), todos de natureza gravimétrica. Os três métodos não foram concordantes entre si,

2. Determinação do teor de lignina em amostras vegetais através de três métodos analíticos e correlação com digestibilidade in vitro / Determination of lignin concentration in vegetable samples through three analytical procedures and correlation with in vitro digestibility
The in vitro digestibility either dry matter or cell wall of different vegetable samples arranged in three groups: forages, wood or bamboos was correlated with lignin concentration determined through three analytical methods. The employed methods were: acid detergent lignin (ADL), Klason lignin (KL) and potassium permanganate lignin (PerL). Lignin concentrat

3. Relationship between Fungal Biomass Production and the Brightening of Hardwood Kraft Pulp by Coriolus versicolor
The white-rot fungus Coriolus versicolor increased the brightness of hardwood kraft pulp by two mechanisms depending on the concentration of available nitrogen. In low-nitrogen conditions, the brightening process was a chemical effect mediated by the fungus, associated with the removal of residual lignin in the pulp; kappa number was used as an indicator of
