Comparative Study of Antibiotic Resistance in Lactobacillus Species Isolated from Fermented Cassava and Corn

Background: This study aimed to conduct a comparative study of antibiotic resistance in Lactobacillus species isolated from fermented cassava and corn samples. Key objectives included identifying antibiotic resistance profiles and evaluating interspecies correlations to support the development of functional probiotics. Methods: A total of nine (9) bacterial strains, including Lactobacillus fermentum, Lactobacillus ghanensis, Lactobacillus delbrueckii, Lactobacillus plantarum, Lactococcus lactis, Lactobacillus reuteri, Lysinibacillus sphaericus, Bacillus cereus, and Bacillus pacificus, were analyzed for resistance against twelve (12) antibiotics. Correlation coefficients and paired statistical analysis were performed to assess interspecies relationships and variations, with p-values indicating significance. Correlations were evaluated using Pearson’s coefficient (r), and significance was set at p
