Sažetak
Novel chitosan/alginate microcapsules simultaneously loaded with copper and Trichoderma viride have been prepared and characterized. Information about intermolecular interactions between biopolymers and bioactive agents were obtained by Fourier transform infrared spectroscopy. Encapsulation of Trichoderma viride spores and the presence of copper in the same compartment do not diminish their activity. Dependence of microcapsule loading capacity and efficiency, swelling behavior and releasing depends on both, the size of the microcapsule and bioactive agents. The in vitro copper release profile was fitted to Korsmeyer–Peppas empirical model. Fickian diffusion was found to be a rate-controlling mechanism of release from smaller microcapsules, whereas anomalous transport kinetics controlled release from larger microcapsules. Trichoderma viride spores releasing profile exhibited exponential release over the initial lag time. Results obtained opened up perspectives for the future use of chitosan/alginate microcapsules simultaneously loaded with biological and chemical agents in the plant nutrition and protection.
