    Abstract: Disclosed is a precursor protein comprising a cleavable sequence of desired peptide (Pep) elements and auxiliary peptide (Aux’) elements of the general formula (Pep-Aux’)x or (Aux’-Pep)x where x >1, wherein: the Aux’ elements are identical or different and comprise an amphiphilic alphahelix-forming peptide, said amphiphilic peptide comprising a sequence segment of at least seven peptidically linked amino acids capable of forming an amphiphilic alpha-helix, wherein the amino acid residues of said helix in its vertical projection are separated into a hydrophobic half and a hydrophilic half of the helix, the hydrophobic half of the helix having at least 3 adjacent, in the vertical projection, identical or different hydrophobic amino acid residues, and the hydrophilic half of the helix having at least 3 adjacent, in the vertical projection, identical or different hydrophilic amino acid residues; the Pep elements are identical or different and comprise the amino acid sequence of identical or different peptide molecules having a sequence length of 5 to 70 amino acid residues; the Pep elements are flanked by cleavage sequences which enable the Pep elements to be specifically cleaved out of the precursor protein; and Pep is a cationic antimicrobial peptide and Aux’ is an anionic peptide forming an amphiphilic alpha helix. Further disclosed is the use of an amphiphilic peptide as protective peptide for recombinantly producing an antimicrobial desired peptide different therefrom; wherein said amphiphilic peptide comprises a sequence section of at least seven peptidically linked amino acids capable of forming an amphiphilic alpha-helix, wherein the amino acid residues of said helix in its vertical projection are separated into a hydrophobic half and a hydrophilic half of the helix, the hydrophobic half of the helix having at least 3 adjacent, in the vertical projection, identical or different hydrophobic amino acid residues, and the hydrophilic half of the helix having at least 3 adjacent, in the vertical projection, identical or different hydrophilic amino acid residues.

    Abstract: The present invention relates to novel isolated bacterial strains, which are members of the genus Paenibacillus, originally isolated from soil and showing antagonistic activity against a broad range of pathogens and being capable of producing antimicrobial metabolites. It was found that the strains Lu16774 and Lu17007 belong to a novel subspecies named Paenibacillus polymyxa ssp. plantarum while the strain Lu17015 belongs to a novel species which is proposed to be Paenibacillus epiphyticus. The present invention also relates to microbial pesticide compositions comprising at least one of such novel bacterial strains, whole culture broth or a cell-free extract or a fraction thereof or at least one metabolite thereof, and/or a mutant of at least one of said novel bacterial strains having all the identifying characteristics of the respective bacterial strain or whole culture broth, cell-free extract, fraction and/or metabolite of the mutant thereof showing antagonistic activity against plant pathogens. The present invention also relates to a method of controlling or suppressing plant pathogens or preventing plant pathogen infections by applying such composition. The present invention also relates to novel fusaricidin-type compounds which are metabolites produced by the strains of the present invention.
