“…Supplementing poultry feed with glycerin is also justified because dietary glycerin has a high absorption rate (Yang et al 2012), because glycerin is absorbed both by active and passive processes in the intestine (Kato et al 2004;Ohta et al 2006), and is converted into an energy source through multiple metabolic processes. Several authors have shown that up to 5% glycerin can be included in broiler chicken diets (Cerrate et al 2006;Kroupa et al 2011; al.…”

This study evaluated the performance and the quality and fatty acid profile of eggs from laying hens fed diets containing mixed crude glycerin (MCG; 80% vegetable fat + 20% animal fat). A total of 240 39-week-old Hy-Line W36 laying hens were distributed according to a completely randomized experimental design into six treatments consisting of graded MCG dietary inclusion levels (0, 1.5, 3.0, 4.5, 6.0, and 7.5%), with five replicates of eight birds each. Feed intake linearly decreased (p<0.05) with increasing MCG inclusion levels. The percentages of myristic, palmitic, and α-linolenic acids in the eggs linearly decreased as MCG dietary levels increased (p<0.05), while α-linoleic acid, polyunsaturated fatty acids (PUFA) and ω-6/ω-3 ratio linearly increased. Excreta moisture linearly increased with increasing levels of MCG inclusion (p<0.05). MCG may be included in up to 7.5% in layer feeds without impairing performance or egg quality, but levels up to 5.54% reduce SFA egg content. However, the inclusion of MCG in layer diets increases ω-6/ω-3 ratio in the eggs.

“…Teóricamente puede obtenerse 0,1 l de glicerol por cada litro de biodiesel, además de metanol y agua (Singhabhandhu y Tezuka, 2010;Chatzifragkou et al, 2011). La glicerina es empleada en la industria alimentaria y farmacéutica bajo los estándares USP (United States Pharmacopeia) y FCC (Food Chemicals Codex); en la producción de dinamita (Rincón y Martínez, 2009;Posada-Duque y Cardona-Alzate, 2010), cosméticos, pintura, pulpa, papel, cuero y textiles (Pagliaro y Rossi, 2008;Singhabhandhu y Tezuka, 2010;Chatzifragkou et al, 2011); como sustrato para la producción de metabolitos, tales como los ácidos orgánicos, 1,3-propanodiol, ácido cítrico, polioles y lípidos (Yazdani y Gonzalez, 2007;Chatzifragkou et al, 2011), en la dieta de rumiantes y algunos otros animales (Yang et al, 2012), y en la producción de etanol combustible, utilizando cepas de Escherichia coli (Posada y Cardona, 2010) …”

Para más información escríbanos a pccmca@ucr.ac.cr ResumenEl objetivo de este trabajo fue destacar la importancia económica del aprovechamiento óptimo de los productos y subproductos de la palma aceitera. En Colombia este cultivo en etapa productiva puede generar anualmente en promedio 3,14 t de aceite, y hasta 21,68 t de residuos sólidos y líquidos por hectárea. Estos datos permiten estimar que para las 450 131 ha presentes en Colombia en 2014, se produjeron más de nueve millones de toneladas de residuos sólidos y líquidos; la biomasa fue empleada principalmente para la generación de energía y vapor, liberando el contenido de carbono nuevamente al ambiente. Estos residuos poseen un gran potencial en muchas industrias, algunas por desarrollar, por lo que, es de especial importancia intentar maximizar el uso de los residuos para generar beneficios económicos y ambientales. Ejemplo de ello es la torta de palmiste, con un potencial nutricional en la alimentación animal, la fibra en la industria de biocompuestos, la biomasa y el estípite en la industria maderera, el glicerol, el biodiesel y los efluentes líquidos en la industria química y biotecnológica. El aprovechamiento de estas materias primas puede ayudar a establecer un balance positivo en el cultivo de esta especie.Palabras clave: biocombustibles, gases de efecto invernadero, efluentes líquidos, Colombia. AbstractThe objective of this research was to highlight the economic importance of the optimal use of products and byproducts of oil palm. In Colombia, productive crops per hectare can generate, over one year, an average of 3.14 tons of oil, and up to 21.68 t of solid and liquid waste when the plant is on a productive stage. These data allowed the researcher to estimate that more than nine million of t of solid and liquid waste was produced from the 450 131 ha present in 2014, in Colombia; the produced biomass was used to generate energy and steam, releasing carbon dioxide back again into the environment. These residues have great potential in many industries, some to be developed, therefore, it is of special importance to try to maximize the use of waste produced by oil palm production, to generate economic and environmental benefits. An example of this is the palm kernel cake, with a nutritional potential in animal feed, fiber in the biocompound industry, biomass and stipe in the timber industry, glycerol, biodiesel, and liquid IntroducciónLa agricultura es la actividad básica para el hombre, ha generado grandes cambios a través de la historia; mediante su expansión, los seres humanos han transformado los ecosistemas más rápida y extensamente que en ningún otro período de la historia humana, permitiendo resolver de forma rápida las demandas crecientes de alimento, agua, madera, fibra y combustible (Reid et al., 2001).Colombia, es uno de los productores agrícolas con una div...

“…These additions help animals to gain weight through efficient feed consumption [137]. It can thus be used to replace corn in animal diet [138]. The other advantages associated with the use of CG are weighed down by presence of impurities, especially methanol [139][140][141].…”

The biodiesel industry has the potential to meet the fuel requirements in the future. A few inherent lacunae of this bioprocess are the effluent, which is 10 % of the actual product, and the fact that it is 85 % glycerol along with a few impurities. Biological treatments of wastes have been known as a dependable and economical direction of overseeing them and bring some value added products as well. A novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics. In this article, we have opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed.
