Sažetak
Plant pathogenic bacteria and fungi are one of the biggest threats to global commercial crop and food production resulting in significantly increased cost of production, and reduced crop establishment and productivity. One of the most important tasks in plant protection is the process of using new agroecological formulations based on silver ions. The aim of this investigation is to explore how the method of ionic-gelation encapsulation method can produce biopolymer microcapsules enriched with silver ions, which could increase the stability and viability of silver ions over a longer time period. The optimization process of silver ion encapsulation in the biopolymers microcapsules was performed under optimal conditions of concentrations of alginate, chitosan, and calcium chloride: (1.5% sodium alginate, 0.5% chitosan, 2% calcium chloride). At the optimal point microcapsules enriched with silver ions were produced and physicochemically characterized (microcapsules size, encapsulation efficiency, loading capacity, particle size). The process of encapsulation in biopolymer microcapsules did not have a negative impact on the properties of the silver ions and its activity remains very high. Also, the silver ions release data were fitted to the Korsmeyer-Peppas model and the n exponent indicated that the release mechanism was Fickian. The electrostatic interactions between silver ions, alginate and chitosan were confirmed by infrared spectroscopy. The obtained results showed that silver ions could be successfully encapsulated and applied in the process of plant protection against plant pathogens.
