Abstract: An orally administered vaccine application is a part of strategies on veterinary vaccine development. Soy protein isolate (SPI) has been scientifically tested in various studies as a potent drug carrier. Mastitis is one of the livestock diseases mainly caused by Streptococcus agalactiae, which can be controlled through vaccination programs. This study aimed to determine loading efficiency (LE) and loading capacity (LC) in various formulations of SPI, sodium alginate loaded with inactivated group B streptococcus trehalose (GBS-trehalose) combination as oral vaccine carrier candidates. Based on the SPI solubility test, we obtained a high percentage of solubility at pH 6-10, ranging from 83.40% to 99.39%. The prepared GBS-trehalose loaded SPI-alginate microparticles (pH 6) with a ratio of 1.03:1 yielded LE of 47.37 % and 3.79% LC. The lower concentration of GBS-trehalose loaded to SPI-alginate with ratios 0.876:1 and 0.657:1 yields a higher LE of 70.77% to 92.08% and 6.66% to 10.52% LC, confirming the valuable microencapsulation properties of SPI-alginate and the suitability of the ratio formulations. These results demonstrate that SPI-alginate is relevant for developing an inactivated bacterial vaccine carrier for the oral route. More research is needed for microparticles characterization, release capability and in vitro stability under various environmental conditions.
