Molecular Profiling and Bacteriocin Production of Endophytic Bacteria Isolated from Solanum trilobatum L. Leaves

Bacteriocins are bacterial ribosomal synthesized antimicrobial peptides lethal to bacteria other than the producing strain (Nissen-Meyer and Nes, 1997). Members of the Bacillus group are considered good producers of antimicrobial substances, including peptide and lipopeptide antibiotics, and bacteriocins (Stein et al., 2005). Bacteriocins from Bacillus species offer a much broader spectrum of potential applications compared with lactic acid bacteria bacteriocins. Almost every plant on the earth hosts endophytic bacteria that could serve as potential source of novel natural products, which are of a great potential not only in medicine but also in various other sectors of the biotechnology industry (Strobel, 2002; Guo et al., 2008). However, endophytes from medicinally important plants are of a great interest, especially in understanding their potential medicinal properties and to explore their potential applications (Mehanni and Safwat, 2010).
