Complete Genome Sequence of Bacillus velezensis GQJK49, a Plant Growth-Promoting Rhizobacterium with Antifungal Activity

Bacillus velezensis GQJK49 is a plant growth-promoting rhizobacterium with antifungal activity, which was isolated from Lycium barbarum L. rhizosphere. Here, we report the complete genome sequence of B. velezensis GQJK49. Twelve gene clusters related to its biosynthesis of secondary metabolites, including antifungal and antibacterial antibiotics, were predicted.

Bacillomycin D: an iturin with antifungal activity against Aspergillus flavus.

AIMS In a search for an antifungal peptide with a high activity against Aspergillus flavus, Bacillus subtilis AU195 was selected from a collection of isolates with antagonistic activity against A. flavus. METHODS AND RESULTS To identify the antifungal peptides, a protein purification scheme was developed based on the detection of the antifungal activity in purified fractions against A. flavus...

Draft Genome Sequence of Bacillus amyloliquefaciens Strain RHNK22, Isolated from Rhizosphere with Biosurfactant (Surfactin, Iturin, and Fengycin) and Antifungal Activity

Bacillus amyloliquefaciens strain RHNK22 isolated from groundnut rhizosphere showed direct and indirect plant growth-promoting traits along with biosurfactant activity and reduction in surface tension of water. Biosurfactants were identified as lipopeptides (surfactin, iturin, and fengycin) by molecular and biochemical analysis in our studies.

Isolation and molecular characterization of a novel strain of Bacillus with antifungal activity from the sorghum rhizosphere.

We looked for bacterial strains with antifungal activity in the sorghum rhizosphere. A prescreening procedure to search for hemolytic activity among the isolated strains allowed us to detect good fungitoxic activity in a bacterial isolate that we named UM96. This bacterial isolate showed strong growth inhibition in bioassays against the pathogens Diaporthe phaseolorum, Colletotrichum acuta...

Isolation and characterization of new iturins: iturin D and iturin E.

Two new antibiotics, iturin D and iturin E, were isolated from a strain of Bacillus subtilis producing iturin A. These compounds belong to the iturin group, the acid hydrolysates contained alpha-amino acids Asp3, Glu1, Pro1, Ser1, Tyr1, and a mixture of n-C14, iso-C15, anteiso-C15, iso-C16 and n-C16 beta-amino acids. They differ from iturin A by the presence of a free carboxyl group in iturin D...
