Sažetak
The objective of this work was to investigate influence of copper cation concentration on Trichoderma viride releasing from novel chitosan/alginate microcapsules simultaneously loaded with chemical and biological agents with the intention to improve their delivery to the plants. The in vitro results pointed out remarkable differences in the release behavior of T. viride on copper cation concentration and the presence of chitosan layer on microcapsule surface. The increase in copper cation concentration promoted, but the chitosan layer on microcapsule surface slowed T. viride releasing. The releasing curves were fitted to Korsmeyer– Peppas empirical model. Fickian diffusion was found to be the rate-controlling mechanism at microcapsules without chitosan layer, whereas anomalous transport kinetics (combination of the diffusion mechanisms and Type II transport) controlled release from microcapsules with chitosan layer.
