Resumen
The aims of this study were to compare the viability and biomass production of B. amyloliquefaciens and M. oleovorans in different growth media, and the efficiency of a freeze-drying method as a possible formulation process. B. amyloliquefaciens and M. oleovorans were grown in 100 ml of four different media. Media water activity was modified at 0.99, 0.98, 0.97 and 0.96. Nutrient yeast dextrose broth (NYDB) and molasses soy powder (MSB) media were selected and survival levels of cells were determined before and after the freeze-drying process. B. amyloliquefaciens showed the highest survival after freeze-drying when grown in NYDB medium at 0.99 aw, whereas, at 0.98, 0.97 and 0.96 aw, the highest survival was obtained in MSB medium. M. oleovorans showed the highest survival in MSB medium at 0.99 aw. MSB medium was select for biomass production due to high growth and survival after freeze-drying.
