Resumen en español La transferencia de oxígeno es un parámetro importante en los procesos de fermentación aerobios. Conocer el consumo de oxígeno real del organismo de interés, permite determinar los requerimientos energéticos y de proceso en aireación y agitación. En este trabajo se presenta un tratamiento matemático y metodológico para la determinación de la velocidad específica de consumo de oxígeno (QO2) considerando el tiempo de respuesta del electrodo de oxígeno. Dicha m (mas) etodología se aplicó en la determinación del QO2 del hongo medicinal Ganoderma lucidum, durante su cultivo en un reactor de tanque agitado a escala de laboratorio. Se obtuvo un valor promedio de QO2 de 0,345 mmol O2 (g biomasa.h)-1± 0,0171 sin incluir el tiempo de respuesta del electrodo y de 0,383 mmol O2 (g biomasa.h)-1± 0,025 al incluir dicho parámetro. A mayor tiempo de respuesta del electrodo de oxígeno, mayor será la diferencia entre los valores de QO2. Resumen en inglés The oxygen transfer rate is an important parameter for the aerobic fermentative process. By establishing the real oxygen uptake rate of the target organism we can determine the energetic and process requirements for aeration and agitation. We report in this paper the mathematical and methodological procedure for the determination of the specific oxygen uptake rate (QO2), taking the oxygen electrode response into account. This methodology was applied to the QO2 determinati (mas) on for the Ganoderma lucidum medicinal mushroom while it was being cultured in a stirred reactor in the laboratory. The average value for QO2 was 0.345 mmol O2 (g biomass.h)-1± 0.0171 without taking the electrode time response into account and 0.383 mmol O2 (g biomass.h)-1± 0.025 taking the electrode time response into account. Higher response times of the oxygen electrode resulted in a greater differences between the two QO2 values obtained.

Estudios sobre la biología y ecología de Ceriodaphnia cornuta SARS: UNA REVISIÓN/ Studies on the biology and ecology of Ceriodaphnia cornuta Sars: A review/ Estudos sobre a biologia e ecologia de Ceriodaphnia cornuta Sars: Uma revisão

Resumen en portugués Ceriodaphnia cornuta Sars é um dos três cladóceros mais abundantes nas águas doces tropicais e, dentre estes, é o único que pertence à Família Daphniidae. Este crustáceo está adaptado para tolerar baixas concentrações de oxigênio dissolvido e altas variações de temperatura, características que permitem sua ampla distribuição nas regiões tropicais. C. cornuta pode estar presente em uma grande variedade de corpos de água. Quanto à alimentação, C. corn (mas) uta prefere diatomáceas e algas verdes, sendo capaz de manter altas taxas de crescimento sob condições de escassez de alimento de boa qualidade, ou na presença de alimento com qualidade nutricional baixa, chegando até, em determinados casos, consumir cianobactérias. C. cornuta apresenta um desenvolvimento embrionário curto, rápidas taxas de crescimento dos estágios juvenis e alcança rápidamente a maturidade sexual, tendo fecundidade baixa e longevidade grande. A predação por peixes e pelo invertebrado Chaoborus sp. é uma das interações interespecíficas mais estudadas neste crustáceo, e tem sido constatado que esta predação pode afetar sua abundância e distribuição nos ambientes aquáticos. C. cornuta pode gerar uma série de respostas como mecanismos de defesa diante da predação, destacando-se o polimorfismo, as mudanças em alguns parâmetros da história de vida e a migração vertical. Todos esses aspectos permitem justificar a importância de C. cornuta como organismo-chave para o melhor entendimento da dinâmica das águas doces tropicais e da transferência energética nestes ambientes. Resumen en español Ceriodaphnia cornuta Sars es uno de los tres cladóceros más abundantes en los cuerpos de aguas tropicales y el único perteneciente a la Familia Daphniidae. Este crustáceo está adaptado a tolerar bajas concentraciones de oxígeno y altas variaciones de temperatura, características que le permiten distribuirse ampliamente y estar presente en una gran variedad de cuerpos de agua dulce. En cuanto a su alimentación, C. cornuta es selectiva hacia las diatomeas y las alga (mas) s verdes; puede sostener altas tasas de crecimiento bajo escasez de partículas alimenticias de buena calidad o en presencia de alimento de baja calidad nutricional, pudiendo, en algunos casos, consumir cianobacterias. C. cornuta tiene un desarrollo embrionario corto, rápidas tasas de crecimiento juvenil y una madurez sexual temprana; es de baja fecundidad y larga longevidad. La depredación por peces y por el invertebrado Chaoborus sp. es una de las interacciones interespecíficas más estudiadas en este crustáceo, encontrándose que los depredadores pueden afectar su abundancia y distribución en el ambiente. C. cornuta puede experimentar una serie de respuestas inducidas como mecanismos de defensa, destacándose el polimorfismo, los cambios en algunos parámetros de biohistoria y la migración vertical. Todos estos aspectos ayudan a justificar su importancia como organismo clave para el entendimiento de la dinámica de los cuerpos de agua dulce tropicales y de la transferencia energética en estos ambientes. Resumen en inglés Ceriodaphnia cornuta Sars is one out of three most abundant cladocerans in tropical freshwaters, and the only one belonging to the Daphniidae family. This crustacean can tolerate low concentrations of dissolved oxygen and high temperature variations, two features that allow it to be widely distributed in the tropical freshwaters. Concerning feeding habits, C. cornuta prefers diatoms and green algae. This cladoceran maintains high growth rates under good-quality food condi (mas) tions as well as in low-quality ones, consuming, in the last case, blue green algae. C. cornuta shows a short embryonary development, high growing rates of juveniles and early sexual maturity; it has low fecundity and high longevity. Predation by fish and Chaoborus sp. is an interspecific interaction that has inspired very extensive studies about this crustacean. These studies have shown important effects of predation on its abundance and distribution in freshwaters. C. cornuta may show a series of defense mechanisms as a response to predators, among which polymorphism, changes in some life-history parameters and vertical migration are well documented. All of these aspects justify the importance of C. cornuta as a key organism to obtain a better understanding of dynamics and energy transfer in tropical freshwaters.

Resumen en español El potencial efecto beneficioso de los biopéptidos depende de su capacidad para alcanzar intactos los órganos donde van a realizar su función. Sin embargo, una vez en el organismo dichos péptidos deben atravesar una serie de barreras potenciales que pueden inactivarlos. Las enzimas digestivas, la absorción a través del tracto gastrointestinal y las proteasas sanguíneas pueden producir la hidrólisis de los mismos y generar fragmentos inactivos o con una actividad m (mas) ayor que su secuencia precursora. Por lo tanto, es difícil establecer una relación directa entre la actividad biológica in vitro e in vivo debido principalmente a la biodisponibilidad de los péptidos después de la administración oral. Esto debe ser tomado en cuenta en el momento de transferir los resultados de la investigación a la industria de alimentos para la elaboración y comercialización de productos nutracéuticos. Palabras clave: Péptidos, actividad biológica, digestión, absorción, biodisponibilidad Resumen en inglés The potential beneficial effect of the biopeptides depends on its capacity to reach intact the organs where they will carry out their function. However, once in the organism the peptides should cross a series of potential barriers that they should avoid in order not to be inactivated. The digestive enzymes, the absorption through the gastrointestinal tract and the sanguine proteases can produce the hydrolysis of them and to generate inactive fragments or with a higher act (mas) ivity that its sequence precursor. Therefore, it is difficult to establish a direct relationship among the biological activity in vitro and in vivo, due mainly to the peptides bioavailability after oral administration. This should be taken into account at the moment to transfer the results from the investigation to the food industry for the elaboration and commercialization of nutraceutical products
