Abstract:
In the present study, novel natural fiber composites, consisting of untreated and alkali(NaOH)-treated chopped henequen fibers and polyamide 6 (PA6), were produced by the hopper feeding and side feeding of henequen fiber, upon the extrusion process, and then by an injection molding process, respectively. The effects of the alkali treatment and fiber feeding route on the heat deflection temperature, tensile, flexural, and Izod impact properties of henequen fiber/PA6 composites were investigated. The composite properties were increased by alkali treatment and further increased, considerably, by side feeding of the henequen fiber, being supported by inspecting the fiber length distribution and the fracture surface of resulting composites. It was clarified that the side feeding of chopped henequen fibers was preferable to increase the composite properties, compared to hopper feeding. This study may be worthy of processing and manipulating the properties of novel natural fiber composites, consisting of agave plant-derived henequen fiber and engineering plastic PA6.

Abstract:
In this work, henequen and ixlte plant fibers were carbonized in a horizontal quartz tube furnace. Several carbonized and non-carbonized fiber fabric configurations were impregnated with a bio-based epoxy resin through the infuseon process. The infrared spectra revealed characteristic bands of styrene instead of organic compounds, representing that the carbonization procedure was adequate to carbonize the plant fibers. The porosity volume ratio for the non-carbonized henequen laminates showed the highest number of voids >1.9%, and the rest of the composites had a similar void density between 1.2–1.7%. The storage modulus of the non-carbonized and carbonized henequen laminates resulted in 2268.5 MPa and 2092.1 MPa, respectively. The storage modulus of the carbonized ixtle laminates was 1541.4 MPa, which is 37.8% higher than the non-carbonized ixtle laminates and 12% higher than henequen composites. The laminates were subject to thermal shock cycling, and tomography scans revealed no alterations on the porosity level or in the cracks after the cycling procedure. Thermal shock cycling promoted the post-curing effect by increasing the glass transition temperature. The viscoelastic results showed a variation in the storage modulus when the carbonized fiber fabrics were located between natural fiber fabrics, which was attributed to more excellent compaction during the infusion process. Variations in the viscoelastic behavior were observed between the different types of natural fibers, which influenced the mechanical properties.

Abstract:
Seven Kluyveromyces marxianus isolates from the elaboration process of pulque and henequen mezcal were characterized. The isolates were identified based on the sequences of the D1/D2 domain of the 26S rRNA gene and the internal transcribed spacer (ITS-5.8S) region. Genetic differences were found between pulque and henequen mezcal isolates and within henequen mezcal isolates, as shown by different branching patterns in the ITS-5.8S phylogenetic tree and (GTG)5 microsatellite profiles, suggesting that the substrate and process selective conditions may give rise to different K. marxianus populations. All the isolates fermented and assimilated inulin and lactose and some henequen isolates could also assimilate xylose and cellobiose. Henequen isolates were more thermotolerant than pulque ones, which, in contrast, presented more tolerance to the cell wall-disturbing agent calcofluor white (CFW), suggesting that they had different cell wall structures. Additionally, depending on their origin, the isolates presented different maximum specific growth rate (µmax) patterns at different temperatures. Concerning tolerance to stress factors relevant for lignocellulosic hydrolysates fermentation, their tolerance limits were lower at 42 than 30 °C, except for glucose and furfural. Pulque isolates were less tolerant to ethanol, NaCl, and Cd. Finally, all the isolates could produce ethanol by simultaneous saccharification and fermentation (SSF) of a corncob hydrolysate under laboratory conditions at 42 °C.

Abstract:
Henequen (Agave fourcroydes Lem.) is a well known fiber producing plant cultivated in the Yucatán peninsula in México. Recent studies revealed that the stem locally known as “piña” is a reservoir of non structural carbohydrates, which may be fermented to produce an alcoholic spirit similar to mezcal and tequila. In this work we determined the effect of plant age and climatic conditions through the year on sugars and alcohol production. “Piñas” from 5, 8, 15, 18 and 19 year-old plants were harvested in the spring and autumn dry seasons, as well as in the rainy season of one single year. “Piñas” fresh weight varied from 5.2 to 6.7 kg. Harvested “piñas” were cut into small pieces and cooked, followed by pressing to extract their juice; then the juice was fermented with Kluyveromyces marxianus native yeast isolated from henequen, and distilled to obtain two alcoholic products: “ordinary” (monodistilled) and “white” (bidistilled). Results showed that 19 year-old plants yielded the highest volume of ordinary alcohol production (159 mL per liter of juice). ”Piñas” harvested in the dry spring season produced greater quantities of “ordinary” alcohol than those harvested during the dry autumn and in the rainy seasons.

Abstract:
The objective of this work was to develop two prototypes of insulating materials based on natural plant fibers from Agave fourcroydes and Washingtonia filifera, available in Mexico, for their potential use in buildings. For the development of the prototypes, the raw materials were characterized by physical, chemical, and microstructural methods. The samples were prepared by a pulping process after boiling the fibers in a sodium hydroxide solution. We worked with a Taguchi experimental matrix of four variables in three levels, defining as response variables the sample’s thermal conductivity, density, and flexural strength. The results show that the henequen-based insulation obtained a density of 69.8 kg/m3 and a thermal conductivity of 0.0367 W/mK; on the other hand, the palm-based insulation obtained a density of 45.06 g/cm3 and a thermal conductivity of 0.0409 W/mK, which in both cases are like the conductivity values reported by conventional insulating materials, such as expanded polystyrene or mineral wool, and therefore both optimized prototypes are promising as thermal insulators with a high potential to be used in sustainable buildings in Mexico, reducing the energy consumption of air conditioning and the environmental impact associated with the production of materials.

Abstract:
Se presenta evidencia de la obtención de jarabe a partir de henequén (Agave fourcroydes Lem.) y de algunas de sus características de composición. Se utilizaron piñas de henequén de 15 a 18 años de edad que se cocieron durante 4 h a una presión de 1.0 kg cm-2, las que posteriormente se molieron para extraer los jugos que luego se concentraron para obtener el jarabe. Los resultados señalaron que este jarabe contiene 85.7 % de fructosa y 13.7 % de glucosa, 3623 µg g-1 de calcio (Ca), 470 µg g-1 de magnesio (Mg), 665 µg g-1 de potasio (K), 99 µg g-1 de zinc (Zn), 36 µg g-1 de hierro (Fe), 24 µg g-1 de aluminio (Al), 8 µg g-1 de cobre (Cu), 2 µg g-1 de manganeso (Mn) y 1 µg g-1 de cromo (Cr). No se detectó arsénico (As), plomo (Pb) ni cadmio (Cd). Por su riqueza en fructosa, Ca, K y Mg, el jarabe de henequén puede incorporarse en la dieta humana. Este nuevo producto puede dar valor agregado a esta planta y favorecer su preservación.

Abstract:
El estudio de la micromorfología permite comprender el funcionamiento hídrico y la respuesta fisiológica de los cultivos en un sustrato. En la investigación se evaluó el efecto de la micromorfología de mezclas de materiales orgánicos, sobre el contenido de agua y el crecimiento radical de crisantemo. La hipótesis fue que la descripción de la micromorfología de nuevas propuestas de sustratos permitiría inferir la contención, el movimiento del agua y en consecuencia el crecimiento radical. Materiales orgánicos se utilizaron como: aserrín (AP) y viruta de pino (VP), bagazo de henequén (BH), polvo de coco (PC) y un sustrato testigo (turba:Agrolita®). Siete mezclas se evaluaron plantando esquejes enraizados en contenedores con capacidad de 1250 mL. En las mezclas se determinó potencial hídrico (ψ), volumen radical (VR) y peso seco de raíces (PSR); en las hojas, el contenido relativo de agua (CRA) y el uso eficiente del agua (UEA). La micromorfología y la porosidad se caracterizaron a través de la descripción de secciones delgadas. Los resultados indicaron que la forma y distribución del tamaño de partículas, el grado de descomposición de la materia orgánica y el tipo y tamaño de poro, influyeron en la retención y el movimiento del agua en un sustrato. La mezcla de bagazo de henequén y aserrín en una relación 20:80, formó poros de empaquetamiento compuesto, de tamaños entre 50 y 500 μm y superó a la mezcla testigo en el uso eficiente del agua, sin diferencias significativas en potencial hídrico, contenido relativo de agua, volumen radical, ni peso seco de raíces. La combinación de polvo de coco y aserrín de pino formó poros de empaquetamiento compuesto y microporos <50 μm que dificultaron el movimiento del agua y afectaron el crecimiento de las raíces. En la mezcla 20PC:80VP el 80% de las partículas fueron >200 μm, con poros de empaquetamiento simples con 80% de tamaños de 200 a 500 μm que ocasionaron la percolación del agua y una disminución del (ψ) potencial hídrico.
