International Classification:

C07K 1/36
C07K 7/64
C07K 1/30
C12P 19/04

Abstract:

The present invention provides a method of enriching a lipopeptide in a microbial cell culture, the method comprising mixing an amphiphilic sulfonate and/or an amphiphilic sulfate with the cell culture to induce the formation of aggregates containing the lipopeptide, centrifuging the cell culture to generate a supernatant fraction and a pellet fraction, separating the pellet fraction from the supernatant fraction, and mixing the pellet fraction with a polyoxyethylene glycol alkyl ether to release the lipopeptide from the aggregates. Also provided is a method of purifying an exopolysaccharide from a microbial cell culture, the method comprising mixing an amphiphilic sulfonate and/or an amphiphilic sulfate with the cell culture to induce the formation of aggregates, centrifuging the cell culture to generate a supernatant fraction and a pellet fraction, separating the supernatant fraction from the pellet fraction, adding alcohol to the supernatant fraction to precipitate the exopolysaccharide; and removing the precipitated exopolysaccharide from the supernatant fraction.

International Classification:

A01N 63/02
C12N 9/90

Abstract:

The present invention relates to a composition comprising a biologically pure culture of a fungicidal sp. strain comprising a variant fusaricidin synthetase lacking a functional adenylation domain in the third module. The present invention also provides a composition comprising a biologically pure culture of a fungicidal sp. strain or a cell-free extract thereof comprising at least one Paeniserine and at least one Paeniprolixin. Also provided are isolated compounds and methods of treating a plant to control a plant disease with the disclosed compositions and compounds.

Abstract:

The present invention relates to novel strains of and methods of their use for controlling diseases or pests of a plant. The invention also relates to a fermentation broth obtained by cultivating a gougerotin producing strain, wherein the fermentation broth contains at least about 1 g/L gougerotin. The invention also relates to a method of producing a fermentation broth of a gougerotin producing strain, wherein the fermentation broth contains at least about 1 g/L gougerotin, the method comprising cultivating the strain in a culture medium containing a digestible carbon source and a digestible nitrogen source under aerobic conditions, wherein the culture medium contains an amino acid at a concentration effective to achieve a gougerotin concentration of at least 1 g/L. The present disclosure also relates to the molecular cloning of a gougerotin biosynthetic gene cluster from , and identification of individual genes in the gene cluster as well as the proteins encoded thereby. A gougerotin gene cluster comprising 13 open reading frames (ORFs) is located within a genetic locus of
