The extraction of lutein from marigold petals using a surfactant-based aqueous two-phase system is reported. In this work, the effectiveness hydrophilic-lipophilic balance surfactants on performance for petal powder was demonstrated solutions wide range non-ionic surfactants. response surface methodology applied to obtain optimised conditions maximum lutein. At (Temperature = 37.5 °C, S/L 0.003...

The intracellular distribution and diffusivity of adenosine triphosphate (ATP) was studied by cryomicrodissection of individual Rana pipiens oocytes. We measured ATP concentrations in the nucleus, in animal and vegetal hemisphere cytoplasm, and in an intracellular reference phase (iRP, a microinjected gelatin "organelle") which samples diffusive ATP. Regional concentrations were not equal: nucl...

Microalgae are a valuable source of enzymes and active ingredients due to their biochemical variability, health-beneficial properties, lower production cost viability on an industrial scale. In addition, the growing demand for sustainable products constitutes microalgae as viable resource development range innovative products. present work, proteolytic activity Arthrospira platensis lysate was ...

Computer algebra systems (CASs) and automated theorem provers (ATPs) exhibit complementary abilities. CASs focus on efficiently solving domain-specific problems. ATPs are designed to allow for the formalization and solution of wide classes of problems within some logical framework. Integrating CASs and ATPs allows for the solution of problems of a higher complexity than those confronted by each...
