“…Members of the iturin family containing one ␤ -amino fatty acid and seven ␣ -amino acids, such as mycosubtilin, bacillomycin D and iturin A, exhibit strong antifungal and hemolytic activities and a limited antibacterial activity [Maget-Dana and Peypoux, 1994]. Though the toxicity toward fungi of bacillomycin D and fengycin mainly rely on their membrane permeabilization properties [Bonmatin et al, 2003;Deleu et al, 2005;Vanittanakom et al, 1986], their biological activities differ due to diversity of polar groups and amino residues [Ongena and Jacques, 2008].…”

In previous studies, Bacillus amyloliquefaciens C06 has been proven to be effective in controlling brown rot of stone fruit caused by Monilinia fructicola. When tested in vitro, cell-free filtrate of B. amyloliquefaciens C06 significantly inhibited mycelial growth and conidial germination of the fungal pathogen. This study aimed to determine the role of the antifungal compound(s) in the cell-free filtrate of B. amyloliquefaciens C06 by an approach combining a DNA-based suppression subtractive hybridization (SSH) method with MALDI-TOF-MS analysis. It was demonstrated that B. amyloliquefaciens C06 harbored two genes, bmyC and fenD, involved in biosynthesis of bacillomycin D and fengycin, two lipopeptides belonging to the iturin and fengycin family, respectively. To determine the roles of bacillomycin D and fengycin of B. amyloliquefaciens C06 in suppressing M. fructicola, the mutants of B. amyloliquefaciens C06 deficient in producing bacillomy- cin D, fengycin or both were constructed, and evaluated in vitro together with the wild-type B. amyloliquefaciens C06. The results indicated that bacillomycin D and fengycin jointly contributed to the inhibition of conidial germination of M. fructicola, and fengycin played a major role in suppressing mycelial growth of the fungal pathogen.

ResumenEl presente estudio documental evalúa el efecto biocontrolador del género Bacillus sp contra hongos fitopatógenos de plantas, particularmente, a través de relaciones antagónicas inductoras de muerte celular en términos inminentemente naturales. Fusarium oxysporum se encuentra muy relacionado con casos de marchitez vascular y pudrición de raíz en variedad de plantas, obstrucción de los vasos que permiten la circulación vegetal hasta causar amarillamiento de las hojas por imposibilidad en el transporte de nutrientes, causal de grandes pérdidas económicas en el campo agrícola nacional. Se han establecido varios mecanismos para controlar este hongo micelial dentro de las que se encuentran el uso extensivo y variable de agroquímicos y pesticidas, práctica que por sus efectos nocivos con el medio ambiente se ha comenzado a reemplazar por empleo de especies del género Bacillus. La acción biocontroladora de este género bacteriano esta mediada por su perfil bioquímico ya que son productores de múltiples metabolitos biológicamente activos, en el caso de Bacillus subtilis de Iturin A y fengycin y en Bacillus brevis de gramicidina S (1-5) son capaces de inhibir el desarrollo y crecimiento normal de otros microorganismos, lo que sugiere su utilización para el biocontrol de plagas en aras al fortalecimiento de los actuales estándares de calidad en los procesos ambientales. Palabras Clave: Bacillus sp, Fusarium oxysporum, biocontrolador, genes, metabolitos.

“…The potential activities of surfactin include antibiotic and membrane effects (6), the ability to disturb lipid monolayers and affect biological membranes (12), altering the integrity of the lipid membrane with the formation of ion channels (7) and causing leakage and lysis of lipid membranes (14). The potential of some kinds of lipopeptides to alter surface tension or show antimicrobial activity is directly linked to their molecular structure (5,11).…”
