This study aimed to characterize Lysinibacillus sp. PWR01, isolated from rubber latex, through comprehensive integrated phenotypic, functional, and genomic analyses to evaluate its biotechnological potential. Morphological, biochemical, and physiological assays were combined with whole-genome sequencing, comparative genomics, and genome functional annotation. PWR01 demonstrated strong tolerance to acidic pH and bile salt conditions, high sporulation efficiency, and pronounced antibiofilm activity against Pseudomonas aeruginosa. In addition, the cell-free supernatant inhibited Streptococcus agalactiae and Aeromonas hydrophila in a concentration-dependent manner across a range of temperature and pH conditions. The strain also exhibited notable antioxidant activity and maintained high cell viability during storage. Genome analysis revealed a 5.0 Mb genome with 4909 predicted genes and 97% average nucleotide identity (ANI) with Lysinibacillus fusiformis. Functional annotation identified genes associated with sporulation, stress tolerance, carbohydrate metabolism, and secondary metabolite biosynthesis, including polyketide and nonribosomal peptide biosynthetic pathways. Despite the presence of antimicrobial resistance-associated genes, no corresponding phenotypic antimicrobial resistance was detected. These findings collectively highlight Lysinibacillus fusiformis PWR01 as a metabolically versatile and resilient strain with considerable probiotic and biotechnological potential.
