Among cereals, maize has the highest content of bioavailable micronutrients in grain, particularly β-carotene and α-tocopherol, which makes this crop the most appropriate for biofortification. Great genetic variability is a valuable source of micronutrients, and genotypes with enhanced grain content could be used for improvement of comme...

Biopolymers have the ability to absorb large amounts of water or biological fluids. They are swelling and forming hydrogels. Thanks to this, they have found a variety of applications, and among others they can be used to remove some metal ions from the water. Due to its unique structure and exceptional rheological characteristics, microbiological b...
