Identification and characterization of antimicrobial peptide produced by indigenously isolated Bacillus paralicheniformis UBBLi30 strain.

ABSTRACT: The antimicrobial compound produced by Bacillus paralicheniformis UBBLi30 showed UV spectra absorption at 208 nm. Fourier transform infrared (FTIR) revealed characteristic bands for aliphatic chain related to hydrophobic amino acids (l-isoleucine/l-leucine) (3068, 2965 and 2871 cm^-1) and peptide bonds (1538, 1667 and 3312 cm^-1). The proton nuclear magnetic resonance (¹H NMR) showed signals for aromatic amino acid (6.5-9.5 ppm) and alkyl amines (3-4 ppm). The results of carbon (¹³C) NMR showed signals for aromatic, nitro and amide compounds. Besides this, the mass fragments (1422.576 [M+H]⁺, 711.912 [M+2H]²⁺ and 475.174 [M+3H]³⁺ m/z) observed in electrospray ionization mass spectrometry (ESI-MS) were
