Tuning alginate-bentonite microcapsule size and structure for the regulated release of P.putida Rs-198
文献摘要：
In this study,different sizes of microcapsules with alginate and bentonite as natural macromolecular materials were prepared to investigate the release property of Pseudomonas putida Rs-198.The character-istics of three microcapsules were evaluated by SEM,FTIR,TG-DSC,XRD and wall thickness.The sizes of three microcapsules(MA,MB,and MC)were 1270.50,831.79 and 42.52 μm,respectively.First,the encap-sulation efficiency of three MA,MB,and MC microcapsules were 82.20％,90.41％,and 85.84％,respectively.Second,the contact angles of MA and MB samples were similar,while smaller microcapsules MC have higher contact angle(85.05°),indicating poor hydrophilia and decreasing the swelling degrees.Third,the release cumulant of Rs-198 and macromolecule BSA linear stage was fitted to self-established math-ematic model.Results show that the microcapsule size had a considerably positive effect on release detail.The large microcapsule possessed strong leak-tightness for Rs-198 as a slow-release microbial agent.Furthermore,the porosity of microcapsules determined their swelling and release and may affect bacterial growth and survival.In conclusion,the Rs-198 microcapsule with different sizes will be perti-nently selected based on the characteristics of agricultural production requirements.
