Autores: Ramírez Jaspeado, Araceli.
El maíz es el cultivo más importante de México cuya superficie de siembra es de 8 millones de hectáreas con un rendimiento promedio de 3 ton/ha. Su aprovechamiento involucra los granos, tallos, espigas, raíces, olote y brácteas (“hoja para tamal”) utilizados para diversos propósitos en la alimentación humana, animal, medicinal e industrial. Se ha considerado que la principal forma de consumo del maíz es a través de la tortilla, donde, alrededor de 12.3 millones de toneladas de maíz se consumen en esta forma. En este sentido, los maíces mejorados han sido esenciales para dicho propósito, sin embargo, el uso de los maíces nativos o criollos, también ha sido de gran importancia ya que son un reservorio de la variabilidad genética y han sido la base de la...

Autores: Robert, Rene; Parisi, Guilina; Pastorelli, Roberta; Poli, Bianca Maria; Tredici, Mario.
In an attempt to provide cost-effective alternatives to live microalgae and to simplify hatchery-nursery procedures, concentrated microalgae appear to be very promising. Due to its high preservation ability, Prasinophytes appear to be good candidates for such alternative diets. Nevertheless, in a previous study the utilization of Tetraselmis suecica was only conceivable for old Crassostrea gigas larvae. In the present work its nutritional quality has been accordingly searched on ]apanese oyster's juveniles. Whatever the assemblages and condition, fresh or preserved microalgae, T. suecica did not allow an adequate postlarval development in C. gigas.

Autores: Herrera,Esperanza; Murillo,Manuel; Berumen,Leslie; Soto-Cruz,Nicolas O.; Páez-Lerma,Jesús B.
Abstract Opuntia ficus-indica is used in animal feed but has a low protein content (above 4%) in comparison to high-quality forage (above 16%). It is necessary to develop technologies that improve the nutrimental value of Opuntia ficus-indica through the process of solid-state fermentation (SSF). Therefore, the objective of this study was to evaluate the changes in the chemical composition of Opuntia ficus-indica during the SSF with the yeast Kluyveromyces marxianus ITD00262. Kluyveromyces marxianus ITD00262 was grown in glucose, peptone, yeast (GPY) broth, at 28 °C and pH 4.8 for 12 h. Opuntia ficusindica was incubated in SSF at 28 °C without inoculation (T1) or inoculated with K. marxianus ITD00262 (T2). Fermented samples of Opuntia ficus-indica were...
