Agar-diffusible secondary metabolites secreted by B. halotolerans Cal.l.30 and annotated through UHPLC-HRMS analysis. The compounds were putatively annotated based on isotope distribution and the accurate mass (±5 ppm). The precise masses revealed the presence of compounds (A) mojavensin A, (B) fengycin A, (C) Surfactin A C13, (D) Surfactin A C15, (E) L-dihydroanticapsin (K) bacillibactin, (G–J) four analogues of bacillaene, known as bacillaene A, dihydrobacillaene, bacillaene B and bacillaene C, respectively, (F,L,M) azelaic acid, 15-hydroxypentadecanoid acid and 2-hydroxyphenylacetic acid, respectively.
