A new strain of Bacillus subtilis isolated from deep-sea core sediment sample (1400 m depth) produced antimicrobial peptides (AMPs) when cultured at 50 and 100 bar pressure conditions. The minimum inhibitory concentrations (MIC) showed that the AMPs had potent activity against V. cholerae and K. pneumoniae. AMPs extracted from cells grown at ambient and elevated pressure conditions exhibited distinct antifungal and antibacterial activities. Analysis of genes encoding AMPs revealed the presence of srfAA, sbo and bmyB biosynthetic genes. GC–MS analysis confirmed substantial accumulation of unsaturated fatty acids in membrane lipids of the cells in response to elevated pressure.
