- In vitro degradation and gas production of glycerin generated in the biodiesel production chain Livia Soares Silva Leilson Rocha Bezerra Aderbal Marcos de Azevedo Silva Heloisa Carneiro Milena Nunes Moreira Ronaldo Lopes Oliveira Agrociencias NH 3 VFAs Acetate butyrate propionate This study was realized to evaluate the prod uction of gas and volatile fatty acids when glycerin was used to replace four forage spec ies through the use of a semi-automated technique in vitro . The experimental design included 4 treatments and 4 replications. The treatments consisted of increasing levels of glycerin (0, 30, 50 and 70%), which was used to replace the forage plants Elephant grass, sugar cane silage, corn silage and Brachiaria grass. Repl acement of the Brachiaria and Elephant grasses with glycerin linearly reduced the production of methane and carbon dioxide and ammonia nitrogen and had a positive effect on forage quality (p < 0.05). With the addition of glycerin, the values for acetate concentration decreased (p < 0.05); however, when added glycerin ther e was increased in propionic and butyric acid concentration (p < 0.05). Substitution of forage species for glycerin by tests for semi-automatic technique in vitro reduce the production of greenhouse gases (CH 4 and CO 2 ) which reduction in energy loss, and increase volatile fatty acids propionic and butyric. 2015 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303141017008 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
