Mulberry anthracnose antagonists (iturins) produced by Bacillus amyloliquefaciens RC-2

Bacillus-Based Biological Control of Plant Diseases

“…The role of fengycins was demonstrated by the very effective disease control provided by treatment of fruits with cLPs-enriched extracts and by in situ detection of fengycins in inhibitory amounts (Touré et al, 2004). To further illustrate the broad range of fungal targets, fengycins were also reported for their antagonistic activity against Fusarium graminearum (Wang et al, 2007), and iturins for their inhibitory effect towards the anthracnose-causing agent Colletotrichum dematium (Hiradate et al, 2002), Penicillium roqueforti (Chitarra et al, 2003), Aspergillus flavus (Moyne et al, 2001), Rhizoctonia solani (Yu et al, 2002), wood-staining fungi (Velmurugan et al, 2009) and nematophagous fungi (Li et al, 2007). In some instances, the fungitoxic activity was clearly related to the permeabilization of spore/conidia therefore inhibiting germination or alternatively to hyphal cell perturbation.…”

Two New Antifungal Cyclic Lipopeptides from Bacillus marinus B-9987

“…12) In the present study, it was found that maribasins A and B are heptapeptides linked to a b-amino fatty acid chain with a length of 15 carbons. Further analysis showed the presence of one Tyr residue, one Ser, one Pro, one Gln and three Asn residues like iturin family.…”

In vitro antifungal potential of Bacillus spp.: Isolates as biocontrol agents

“…Fengicini su se pokazali veoma efikasnim u kontroli bolesti plodova voća, izazvanim post-žetvenim patogenima in situ [9]. Za fengicin je takođe zabeležena antagonistička aktivnost protiv Fusarium graminearum [10], dok je za iturin uočena inhibitorna aktivnost prema izazivaču antraknoze Colletotrichum dematium [11], Penicillium roqueforti [12], Aspergillus flavus [13], R.solani [14], prema gljivama koje boje drvo (15) i prema nematofagnim gljivama [16]. U nekim slučajevima, fungitoksična aktivnost je jasno povezana sa permeabilizacijom spora/konidija koja dovodi do inhibicije klijanja ili alternativno do poremećaja ćelija hifa.…”
