Sažetak
The microencapsulation of bioactive agents has been developed in recent years as a new potential tool for ecological and sustainable plant production. Encapsulation in biopolymer matrices has been recognized as an effective method for controlled release of an active agent used for plant protection/nutrition. Polysaccharides such as chitosan and alginate are biopolymers that easy create biodegradable capsules in which an active ingredient can be incorporated using an aqueous system at ambient temperatures. The ability to tailor the physicochemical properties of chitosan/alginate complexes by controlling the degree of association between the functional groups offers a route toward rationalizing biopolymer microcapsule design. The main aim of this study was investigations of intermolecular interactions in mixture of two oppositely charged biopolymers and bioactive agents which will aid in tailoring optimal encapsulation of plant protection/nutrition agents. Biopolymer based microcapsules with a single active agents have extensive applications in agriculture, nevertheless our knowledge of simultaneous encapsulation of biological and chemical agents is still rather limited. Novel sodium alginate/chitosan based microcapsules simultaneously loaded with copper/Trichoderma viride have been prepared. Optimal conditions for preparation of homogeneous, spherical, and smooth microcapsules were established. Physical characteristics, encapsulation efficiency, the loading capacity for bioactive agents, and release characteristics under varying conditions were investigated in vitro. The results revealed the coexistence of copper and Trichoderma viride in microcapsules improved viability of Trichoderma viride and could therefore be an effective vehicle for their delivery to the plants.
