Biochemical characterization uncovers promising antimicrobial properties in bacillus isolates, suggesting alternatives to combat multi-drug resistant infections.
Key Points
B. licheniformis exhibited the broadest antibacterial spectrum with inhibition zones up to 23.0 mm against Staphylococcus aureus.
B. subtilis demonstrated strong antibacterial effects against pathogens, particularly against Staphylococcus aureus and Pseudomonas aeruginosa, with up to 21.0 mm inhibition.
Moderate antibacterial activities were observed in B. cereus and P. polymyxa, while B. megaterium and B. pumilus showed minimal inhibition against some pathogens.
Soil-derived bacillus species highlight potential candidates for the discovery of new antimicrobial agents, addressing antibiotic resistance issues.
