“…Agave plants are perennial evergreen xerophytes containing calcium oxalate crystals at the mesophyll (Blunden et al, 1973). Chávez-Guerrero et al (2010) concluded that Agave salmiana bagasse is an important source of calcium compounds after its incineration. Calcium requirements of bovines have been established between 0.18 and 1.04%, while sheep requirements are between 0.21 and 0.51% (Maynard et al, 1981).…”

ResumenEl objetivo de este trabajo fue evaluar el perfil in vitro de nutrientes de bagazo de Agave salmiana (AS) y Agave weberi cela (AWC) como alternativa para la nutrición de los rumiantes. El bagazo se recogió en Jalpa, Zacatecas durante el año 2010. A partir de las muestras recogidas, se evaluó: materia seca (MS), cenizas, fibra cruda (FC), extracto etéreo (EE), proteína cruda (PC), carbono orgánico total (TOC), detergente neutro de fibra (DNF), y azúcares reductores totales (ART). Macro y microminerales se determinaron por espectroscopia de absorción atómica. Además, se utilizó una técnica de producción de gas in vitro para evaluar la cinética de fermentación, y después de 48 h de incubación de las muestras se utilizaron para cuantificar la producción de AGV. La proteína cruda (%) (2.25 vs 2.73), EE (%) (0.274 vs 0.272), CF (%) (22.15 vs 16,58) y cenizas (%) (2.14 vs 1.81) no fueron diferentes estadísticamente (p> 0.05) entre AS y tratamiento AWC. Los valores de DNF (% MS) fueron estadísticamente diferentes (p< 0.05) entre el AS (45.45) y los tratamientos AWC (52.95). No se observaron diferencias en AGV entre bagazo de agave y de frijol. Los valores de calcio (%) promedio de 3.46 y 1.95 para AS y AWC, respectivamente. Se concluye que, el bagazo de agave representa una alternativa viable para la alimentación de rumiantes, especialmente en la estación seca. AbstractThe aim of this project was to evaluate the in vitro nutrient profile of Agave salmiana (AS) and Agave weberi cela (AWC) bagasse as alternative feedstuffs for ruminant nutrition. The bagasse was collected in Jalpa, Zacatecas during 2010. From collected samples, dry matter (DM), ash, crude fiber (CF), ether extract (EE), crude protein (CP), total organic carbon (TOC), neutral detergent fiber (NDF), and total reducing sugars (TRS) were evaluated. Macro-and micro-minerals were determined by atomic absorption spectroscopy. Also, it was used an in vitro gas production technique to evaluate fermentation kinetic, and after 48h of incubation samples were used to quantified VFA production. Crude protein (%) (2.25 vs 2.73), EE (%) (0.274 vs 0.272), CF (%) (22.15 vs 16.58) and ash (%) (2.14 vs 1.81) were not different statistically (p> 0.05) between AS and AWC treatment. Values for NDF (% DM) were statistically different (p< 0.05) between AS (45.45) and AWC (52.95) treatments. No differences on VFA's were observed among agave bagasse and bean straw. Calcium (%) values averaged 3.46 and 1.95 for AS and AWC-treatments, respectively. It is concluded that Agave bagasse can represents an alternative feedstuffs for ruminants, especially at dry season.

“…Agave bagasse can be used as livestock food, construction material, and for recycled paper elaboration [86], as well as a substrate for edible fungi growth [87]. However, most of it is incinerated, which generates large amounts of ash that can contaminate rivers, bodies of water and damage flora and fauna [88]. Table 3 shows that agave bagasse has a higher cellulose proportion, compared to main lignocellulosic biomass used for bioethanol production.…”

Due to the present renewable fuels demand increase, reduction of second-generation bioethanol production cost is pursued, since it is considered the most promising biofuel, but not yet economically viable. A proposed solution is its production through a simultaneous saccharification and fermentation process (SSF); however, it is necessary to apply temperatures above 40°C, which reduce the viability of traditional ethanologenic yeasts. As consequence, the use of thermotolerant ethanologenic yeast has been suggested, among which the yeast Kluyveromyces marxianus stands out. This chapter addresses the production of second-generation bioethanol through the SSF process, emphasizing the potential of K. marxianus to transform lignocellulosic biomass as agave bagasse. As result, it is proposed to direct the second-generation bioethanol production to the SSF process employing thermotolerant yeasts, to increase process productivity, and addressing the economic barriers.

“…The agave wastes (roots, leaves, bagasse and vinasse) represent almost 50% of the plant weight [49]. Usually, after being dried and burned, a byproduct is generated in the form of residual ash, which is polluting and is called agave biomass ash [47] ( Fig. 8).…”
