This study investigated Lacticaseibacillus paracasei GV17, a potentially probiotic strain, in association with the commercial culture Streptococcus thermophilus STI-12, lactose-free fermented milk. Predictive modeling was used to estimate growth parameters and microbial viability technological characteristics of milk during storage. The initial concentrations strains were 9.80 log CFU/mL for Lc. GV17 9.50 S. STI-12. After eight hours, pH reached 4.6, STI-12 10.90 11.20 CFU/mL, respectively. Baranyi model fitted data, correlation coefficients 0.760 0.852 St. maximum specific rates 0.912 CFU/h 0.882 Regarding characteristics, syneresis decreased by 8.90% after 28 days, indicating greater structural stability, while water retention capacity remained constant. LAB above 10.00 CFU/mL. showed great potential use functional products, prompting further research.
