The objective of this study was to determine if incorporating pre-treated ensiled elephant grass into broiler feed could help meet the rising demand for animal protein. The elephant grass underwent solid-state fermentation for seven days and ensiling in airtight nylon bags for 21 days. Compared to the control, pre-treated ensiled elephant grass exhibited a significant increase in soluble protein concentration (p<0.05) during fermentation. However, the glucose concentration was significantly lower (p>0.05) in the pre-treated ensiled elephant grass after fermentation than in the control. Elephant grass that was solid-state fermented and ensiled with Rhizopus oligosporus demonstrated the highest percentage inhibition (22.4±0.5%). The pre-treated ensiled elephant grass had significantly higher mannanase activity (p<0.05) than the control. In terms of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) activities, there were no significant differences between the control group and the experimental group fed with diets composed of ensiled elephant grass, ensiled elephant grass fermented with R. oligosporus, or solid-state fermented and ensiled elephant grass with R. oligosporus and urea in a 25% maize replacement. In conclusion, ensiled elephant grass can replace 25% maize in broiler starter feed, and the animal feed industry could benefit from the mannanase identified in this study.

tosterols, carotenoids, ferulic acid and phytosterols 5−8) . These compounds serve as antioxidants and have anti-atherosclerotic, anti-diabetic, anti-cancer and anti-inflammatory properties 9,10) .There are still several obstacles in the efforts made to develop rice bran as a functional ingredient, such as the lack of public awareness about its health benefits, a few downstream industries interest in developing rice bran and the quality of rice bran being sub-standard. In addition, rice bran contains anti-nutritional substances such as trypsin inhibitor, hemagglutinin-lecithin and phytic acid, and its instability during storage is another reason that hinders its use as a food ingredient 11,12) .

“…La base de esta actividad económica es el proceso de fermentación, donde se consumen compuestos de alto valor energético (azúcares), obteniéndose sustancias simples, útiles para el metabolismo, por ejemplo, ácidos, gases y alcoholes [1]- [4]. Entre otras aplicaciones se encuentran la remoción de componentes indeseados [3] como por ejemplo reducción de Cr (VI) a Cr (III) en agua residual industrial [5], el consumo de fenantreno [6] y pesticidas [7], [8] por bioaumentación de microorganismos autóctonos y la producción de compuestos de alto valor económico como la vainillina [9], [10], ácido cítrico [11], [12], ácido glutámico [13], [14] e inhibidores enzimáticos [15]. Dentro de los parámetros que influyen en la eficiencia de los procesos de fermentación, y que por lo tanto deben ser controlados, se incluye el oxígeno disuelto [16], la temperatura [17], el pH [18], la composición del medio [19], la osmolaridad y la agitación [20].…”

En este artículo se presenta el diseño de un biorreactor de tipo tanque agitado asistido por microcontrolador utilizando conceptos de simplicidad de uso, modularidad, estética y ergonomía, según las necesidades de la empresa Cibus 3.0. El tanque cuenta con tres partes principales tapa, dispone sus elementos según su uso; caja de sensores, dispositivo que utiliza sensores de pH, temperatura y turbidez del medio; y tanque, con una capacidad volumétrica de 21.5 L. Se acopló un vaporizador de mano genérico como método de esterilización in situ. Para evaluar la eficiencia de esterilización se realizaron muestreos superficiales en las zonas más críticas de formación de biofilms (tapa, tubos, pared, impulsor y flecha), tras fermentaciones de E. coli y R. opacus. Se demostró que la máquina de vapor no cumple con el objetivo de eliminar la contaminación, logrando una esterilización del 92%. Sin embargo, el uso de autoclave permitió el rendimiento esperado de esterilización, esto se comprobó al realizar simulaciones de fermentación con medio estéril y no presentar contaminación al finalizar el ensayo. Se determinó la posibilidad de utilizar sensores de pH, sólidos suspendidos y temperatura tomando parte del medio para cada repetición sin afectar la inocuidad del sistema. De esta manera se introduce un dispositivo capaz de tomar las mediciones por medio de microcontrolador. Con el fin de corroborar la funcionalidad del equipo diseñado, se realizaron tres fermentaciones con la bacteria R. opacus, donde se obtuvieron curvas de crecimiento validando el funcionamiento del diseño alrededor del usuario y del proceso.
