The reactive oxygen species are usually generated by normal cellular activities of the aerobic metabolism and play the role of a signal molecule and beneficial growth regulator. When plants are exposed to stress conditions the concentration of reactive oxygen species increases. Therefore, to neutralize these free radicals and to protect cells from oxidative damage enzymatic and non-enzymatic antioxidant systems are activated. In this paper it was investigated the effect of drought on the activities of antioxidant ...

The treatment of dentin surface with antiseptic solutions will allow to avoid this contamination and thus to assess...

Membrane stability reflects the ability of cell tissues to hold electrolytes under drought condition by retaining the membrane structure of the leaf cell intact. This indicator has been extensively used as selection criterion for different abiotic stresses including drought and high temperature in wheat. A low frequency of injuries is associated with a high stability of cell membrane, which ensures a better tolerance to water stress. The objective of this research was to evaluate the performance and breeding poten...

This study presents an analysis over the action of carboxyl esterase, enzyme used on dough for pasta and noodles. By using carboxyl esterase polar lipids are formed, acting as emulsifiers and interacting with the gluten as well free unsaturated fatty acids are released, which can be converted by lipoxygenase (contained in flour naturally) resulting in the formation of hydroperoxides, which can act as oxidants and lead to protein strengthening and bleaching (oxidation of pigments). Enyzmatic improvement of pasta an...

Yogurt is widely consumed as functional food because of the good taste and nutritional properties (rich in potassium, calcium, protein and vitamins), being an excellent vehicle to deliver probiotics to consumers.
