Polygalacturonase Activity in Yellow Pitaya Peel (Acanthocereus pitajaya)

Acta Biológica Colombiana, 2006
Polygalacturonase activity was determinated in yellow pitaya fruit (Acanthocereus pitajaya). Protein concentrations and activities of the enzyme in the extracts weredetermined. Buffer sodium phosphate 20 mM pH 7,0 with NaCl 0,5 M was the most effective extraction system. The enzyme exhibited optimum activity at pH 5,0 in buffer citrate at 40 °C. The KM

Shaded-Side Supplemental Lighting During Winter Enhances the Overall Productivity of Yellow Pitaya (Hylocereus megalanthus)

Horticulturae
Yellow pitaya (Hylocereus megalanthus) is highly photosensitive and therefore strongly influenced by light availability. In winter, insufficient sunlight often induces a “yin–yang effect”, characterized by physiological disparities between the sunlit and shaded sides of east–west-oriented orchards.

Physicochemical, Granulometric, Morphological, and Surface Characterization of Dried Yellow Pitaya Powder as a Potential Diluent for Immediate-Release Quercetin Tablets

Sci
The growing interest in sustainable materials has encouraged the valorization of agro-industrial byproducts for pharmaceutical, nutraceutical, and food applications. This study evaluated yellow pitaya peel powder, obtained via convective and refractance window drying, as a diluent in immediate-release quercetin tablets.

Stomatal behavior in fruits and leaves of the purple passion fruit (Passiflora edulis Sims) and fruits and cladodes of the yellow pitaya [Hylocereus megalanthus (K. Schum. ex Vaupel) Ralf Bauer]

Agronomía Colombiana, 2013
Las plantas C3 y CAM reaccionan fotosintéticamente diferentes, sin embargo, ambas pueden crecer en la misma zona agroecológica en los trópicos. Por esta razón se evaluó el comportamiento de estomas en frutos y hojas de gulupa y en frutos y cladodios de pitahaya amarilla bajo condiciones naturales en los municipios de Granada y Fusagasugá, departamento ...
