1. Harvesting Microalgal Biomass grown in Anaerobic Sewage Treatment Effluent by the Coagulation-Flocculation Method: Effect of pH
ABSTRACT Harvesting is a critical step in microalgal biomass production process for many reasons. Among the existing techniques available for harvesting and dewatering microalgal biomass, recovery from aqueous medium by coagulation-flocculation has been the most economically viable process, althoughit is highly dependent on pH. This study aims to assess alte

2. In-vitro screening of Kalahari browse species for rumen methane mitigation
The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane m

3. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

4. Imobilização da tanase de Paecilomyces variotii e ação em reações de hidrólise e síntese / Immobilization of tannase from Pecilomyces variotii and reactions of hydrolysis and synthesis
Tannin acyl hydrolase (TAH) known as tannase (EC 3.1.1.20) is an enzyme that hydrolyzes esters of hydrolysable tannins producing gallic acid and glucose as the reaction medium is polar. However, the literature indicates their ability to produce also gallic acid esters in organic media. Our research group has isolated a fungus, Paecilomyces variotii, tannase

5. TRATAMENTO DO EFLUENTE DE UMA RECICLADORA DE PLÁSTICOS UTILIZANDO COAGULANTE NÃO METÁLICO E COMPOSTAGEM / EFFLUENT TREATMENT FROM THE PLASTIC RECYCLING INDUSTRY USING NON-METALLIC COAGULANT AND COMPOSTING
O plástico é considerado a matéria prima mais utilizada no mundo moderno, sua reciclagem é de vital importância para a sociedade e ambiente, contudo esta atividade gera um efluente líquido, com alta carga orgânica, a qual deve ser corretamente tratada. Os métodos tradicionais de tratamento físico-químico, via floculação comumente utilizam coagula

6. Determinação dos mecanismos de ação envolvidos nas atividade antiulcerogenica e antioxidantes de Rhizophora mangle L / Determination of the mechanisms of action in the antiulcerogenic and antioxidant activities of Rhizophora mangle L
The pharmacological research has been focusing on the folk medicine knowledge in order to establish the scientific basis of their pharmacological effects. Nowadays, tannins play a prominent role because of its high antioxidant capacity and, due to the progress made in the analysis and identification of these compounds and their therapeutic possibilities.

7. Utilização de nutrientes e parâmetros de fermentação ruminal em ovinos recebendo dietas com altas proporções de palma forrageira (Opuntia ficus indica Mill) / Use of nutrients and parameters of ruminal fermentation in ovines receiving diets with high percent of spineless cactus (Opuntia ficus indica Mill.)
The experiment was driven with the objective to evaluating the effect of addition of effective fiber, non effective fiber or tannin to diets contends high percents of spineless cactus for ovines about bloat production, rumen general conditions, intake and, dry matter and nutrients digestibility and animals ingestive behavior. Four canullated wethers was used
