Evaluación del tejido adiposo de toretes en pastoreo finalizados con ensilado de caña de azúcar (Saccharum officinarum L.)
Provedor de dados: 32
Autores: Caro Hernández, José Manuel.
Buscando alternativas de alimentación que permitan reducir la pigmentación  amarilla de la grasa en la canal del ganado bovino, se realizó un experimento con  toretes finalizados en pastoreo, en el cual se evaluó el efecto de suplementación con  ensilado de caña de azúcar (EC) en la digestibilidad, comportamiento productivo y  color de la grasa en la canal. Se utilizaron 40 toretes con encastes de Brahaman,  Suizo y Beefmaster (376 + 7.79 kg PV) mantenidos en pastoreo rotacional, en  praderas establecidas con pasto estrella de África (Cynododn plestostachyus) por 90  d. Los tratamientos (T) fueron T1= Sólo pastoreo, T2= T1 + EC, T3= T1 + EC + 15 g  de Fibrozyme®, T4= T1 + EC + 30 g de Fibrozyme®. La suplementación se realizo en  corraletas individuales...

Characterization of Dunaliella salina strains by flow cytometry: a new approach to select carotenoid hyperproducing strains
Provedor de dados: 69
Autores: Mendoza,Héctor; de la Jara,Adelina; Freijanes,Karen; Carmona,Laura; Ramos,Ana Alexandra; de Sousa Duarte,Vanessa; Serafim Varela,João Carlos.
In the present work the characterization of different strains of Dunaliella salina from established cell culture collections and various isolates from solar saltworks located in the Canary Island, as well as one mutant, was carried out in order to assess the existence of intraspecific differences and to determine the potential productivity of each one. Morphological characteristics such as cellular size and cellular complexity and parameters linked to cellular physiology, such as pigment content or cellular growth rate, were determined by means of traditional techniques as well as flow cytometry. Results showed a high morphological and physiological intraspecific variability among the studied strains. Results suggest that the application of the lipidic dye...

Study on the microalgal pigments extraction process: Performance of microwave assisted extraction
Provedor de dados: 5
Autores: Pasquet, Virginie; Cherouvrier, Jean-rene; Farhat, Firas; Thiery, Valerie; Piot, Jean-marie; Berard, Jean-baptiste; Kaas, Raymond; Serive, Benoit; Patrice, Thierry; Cadoret, Jean-paul; Picot, Laurent.
The performance of microwaves irradiation (MAE and VMAE) to extract pigments from two marine microalgae was compared to conventional processes (cold and hot soaking and ultrasound-assisted extraction). Pigments were quantified by RP-HPLC and extraction performance was assessed regarding rapidity, reproducibility and extraction yields. Scanning electron microscopy was used at all extraction steps to assess the impact of the process on microalgal cell integrity. Freeze-drying and pigments extraction preserved microalgae cell integrity (except sonication) and evoked agglutination in superposed cells layers. All processes performed on Dunaliella tertiolecta (chlorophyte) lead to rapid pigments extraction, and equivalent pigments extraction yields, the absence...

Optimization of callus and cell suspension cultures of Barringtonia racemosa (Lecythidaceae family) for lycopene production
Provedor de dados: 63
Autores: Behbahani,Mandana; Shanehsazzadeh,Mehrnaz; Hessami,Mohamad Javad.
Lycopene is present in a range of fresh fruits and vegetables, especially in the leaves of Barringtonia racemosa. The traditional lycopene extraction from the plant is being employed instead of an easy propagation technique like cell culture process from the leaf explants. We intend to assess how lycopene could be extracted via tissue culture under light (illuminance: 8,200 lux under white fluorescent lamps, photoperiod 16 h per day at 25ºC) and dark. Leaf explants of Barringtonia racemosa were cultured on modified Murashige and Skoog (MS), Woody Plant Medium (WPM) and B5 media, supplemented with different concentrations of 2,4-Dichlorophenoxyacetic acid (2,4-D). Optimal conditions for callus induction and maintenance under both dark and light were...
