“…It was found that the PIA formulation had a higher moisture content than the alginate sample, likely due to PIA being more hydrophilic. There have been several reports which support the impact of residual moisture in improving microbial survival in microcapsules. − …”

Poly(itaconic acid) (PIA) is a renewable, biobased, hydrophilic polymer of superabsorbent properties, with the potential to replace synthetic superabsorbent polymers in agricultural applications. Herein, we tested PIA for encapsulation of two model plant growth-promoting bacteria (PGPB), Bacillus subtilis and Pseudomonas fluorescens, using spray drying. Linear PIA was prepared, mixed with PGPB, and spray-dried to form microbe-loaded microspheres. The latter were analyzed for mass yield, moisture content, morphology, and microbial survival. Incubation of the microbes with PIA prior to spray drying showed no significant toxicity. The spray-dried microcapsules were about 1−10 μm in diameter, had a moisture content of about 11%, and contained a viable load of microbes (up to 1 × 10 8 cells/gram of product). The microspheres underwent instantaneous swellingdissolution to release live bacteria. The CFU data showed a survival of about 79% for B. subtilis after spray drying. This work presents PIA as a safe, sustainable, and promising new encapsulation material for microbial inoculants.

“…With the advancement of the chemical industry, various methods have been developed for preparing microcapsules. One commonly used method is the spray drying method [ 11 ], which involves dispersing a solution of core material and wall material into small droplets using a sprayer. These droplets are then exposed to hot air (or cold air) to evaporate the solvent, resulting in a dry powder product.…”

A novel polymeric microcapsule was designed and synthesized using perfluoropolyether silane (PFPE-silane) as a superhydrophobic core material and ethyl cellulose (EC) as a shell material. The effects of the stirring rate and the core-to-shell ratio on the synthesized microcapsules were investigated. The physicochemical properties of the polymeric microcapsules were evaluated using scanning electron microscopy, fourier transform infrared spectroscopy, thermogravimetric analysis, laser particle size analysis, and wettability analysis. The results showed that when the stirring rate was 650 rpm and the core-to-shell ratio was 1:1, well-distributed and uniformly dispersed microcapsules could be obtained. The results also indicated that the prepared polymeric microcapsules were spherical particles with micropores on the surface, and they had an average particle size of 165.71 μm. The EC shells could effectively prevent the thermal decomposition of PFPE-silane during cement hydration, and the PFPE-silane also exhibited excellent hydrophobicity. The specially designed structure of this polymeric microcapsule suggests its potential for enhancing the corrosion resistance of reinforced concrete structures.
