“…Because the agave leaf has no commercial utility, it causes a serious environmental problem (since they are generally burned). At present, there are various research projects for the conversion of this agricultural waste into a value‐added product: ethanol production from agave leaf juice, saccharification of the lignocellulosic residue from bagasse to produce ethanol, and cellulose pulp production from agave leaf bagasse …”

Fermentable sugars production by enzymatic processing of agave leaf juice

et al. 2017

The Mexican mezcal industry annually processes approximately 2.92 × 105 t of mezcal agave, generating roughly 1.46 × 105 t of agave leaves per year, which represents a potential carbon source of at least 8170 t via enzymatic processing of agave leaf juice. This carbon source is considered an attractive alternative to produce biofuels and/or chemical products since it is produced and used without adversely affecting the environment. The aim of this investigation was to determine the effect of temperature, pH, enzyme concentration, and bioreaction time on the enzymatic hydrolysis of agave leaf juice enriched in fructan to maximize the fermentable sugars production from three varieties of mezcal agave, using a low‐cost commercial brand of hydrolase. This process generated a sugar‐enriched juice of 80.07–136.12 g/L of reducing sugars. A Box‐Behnken experimental design and a mathematical surface response analysis of the hydrolysis were used for process optimization.

“…1a). Esta disminución de masa se ha asociado principalmente a degradación térmica de la celulosa, que en el bagazo de caña o para la cascarilla de café es de 44% entre 200 °C-400 °C (Jiménez-Muñoz, et al, 2016) y para el bagazo de A. tequilana es de 63.8% a 360 °C (Naranjo, et al, 2016). Los cambios termogravimétricos observados entre 350 °C y 450 °C se han atribuido a la deshidratación de lignina.…”

En este trabajo se determina el poder calorífico de maderas de huizache (Acacia farnesiana), maguey (Agave salmiana), nopal (Opuntia streptacantha), garambullo (Myrtillocactus geometrizans) y cardón (Pachycereus sp) que provienen de zonas áridas de México y que suelen utilizarse para el calentamiento de agua y cocción de alimentos en el medio rural. La determinación de los poderes caloríficos se realizó por medio de las técnicas de análisis térmico gravimétrico y la técnica de análisis térmico diferencial, ATG-ATD, que es similar a la calorimetría diferencial de barrido (DSC), y mediante una bomba calorimétrica de combustión. En general, los resultados mostraron que el poder calorífico estimado por análisis (ATG-ATD) resulta en todos los casos ligeramente menor que lo estimado con bomba calorimétrica, pero en general son muy próximos entre sí. La máxima variación entre dichos valores en ± 5% se asocia en un intervalo dentro de la incertidumbre de las mediciones realizadas. Para la madera de nopal se encontró que el poder calorífico estimado por ATG-ATD alcanza 11 275 kJ/kg, resultando muy parecido al valor determinado con bomba calorimétrica, 11 605 kJ/kg. En los otros casos estudiados se encuentra una mayor discrepancia entre los valores medidos. El análisis elemental de las maderas y de sus cenizas permite la determinación del parámetro energético ambiental denominado intensidad de carbono de las maderas. Este se estima por medio de espectroscopía de fotoelec-trones emitidos por rayos X (XPS), lo que indica que no hay evidencia de metales tóxicos como los provenientes del carbón; esto demuestra que estas maderas son un producto sutentable y renovable cuando están disponibles para la combustión y obtención de energía calorífica.

Background. The Conventional use of henequen (Agave fourcroydes), has mainly focused on the use of the leaves for the production of fiber. However, there are other components such as the stem (“pineapple”), the spines, and the by-product of fiber generation (leaf juice) in which we should pay attention to. Objective. To provide a systematic analysis of the biotechnological overview from those investigations where the potential of each of the structural components of A. fourcroydes is being studied. Methodology. A systematic review of the literature was carried out, based on the PRISMA protocol (Preferred Reporting Items for Systematic reviews and Meta-Analyses), search for information was carried out in the most prominent databases (Redalyc, SciELO, Scopus, Elsevier, EBSCO, and Google Academic, using A. fourcroydes as the main keyword, using inclusion and later exclusion criteria according to the literature found, in the period from 1990 to 2022, which allowed a broader perspective on this crop and its biotechnological importance. Main findings. In the bibliographic review more information was found on the applications of the plant in an integral way, so that bioactive compounds such as fructans, flavonoids, and sterols can be obtained from the henequen stem, which can be incorporated into animal and human diets, while ethanol has been obtained from the juice of the leaves and the development of that of new materials using the fiber in a native and modified way to obtain fiber-reinforced mortars for its sustainable application in the construction industry. On the other hand, contributions were found on promising alternatives for the use of crops such as modified fibers, and combined with other compounds (composites) for the mechanical reinforcement of new materials. Implications. The literature consulted allows us to report that henequen (A. fourcroydes) is not only cultivated in the Yucatan Peninsula, but also in other regions such as the State of Tamaulipas, Mexico, where its use and commercial exploitation has not well documented. Conclusion. The bibliographical review allows us to deduce that the obtaining of new henequen compounds would revalue their integral use and use in different industries.
