Abstract:
... Enzymes represent a growing market due to their industrial applications, whose use on a large scale is restricted by their high cost of production. This stimulates studies with other sources such as the use of agro-industrial lignocellulosic residues in the medium composition for its production. Thus, in this work, in natura sunflower stalks (Helianthus annuus L.) and its respective alkaline and a ...

Abstract:
... We found experimentally that the elasticity of sunflower oil-in-water emulsions (SFO-in-W) stabilized by Yucca Schidigera Roezl saponin extract, is by >50 times higher as compared to the elasticity of common emulsions. We revealed that strong specific interactions between the phytosterols from the non-purified oil and the saponins from the Yucca extract lead to the formation of nanostructured adso ...

Abstract:
... Nitrogen (N) assimilation is associated with ¹⁴N/¹⁵N fractionation such that plant tissues are generally ¹⁵N‐depleted compared to source nitrate. In addition to nitrate concentration, the δ¹⁵N value in plants is also influenced by isotopic heterogeneity amongst organs and metabolites. However, our current understanding of δ¹⁵N values in nitrate is limited by the relatively small number of compound ...
