Abstract: The present invention relates to a method for the metal-free preparation of a biaryl compound by a photosplicing reaction and its use in the preparation of chemical compounds, preferably of active ingredients e.g. in the fields of pharmaceuticals and agrochemicals. In particular, it refers to a method for the regiocontrolled preparation of a biaryl compound of formula (I): Ar—Ar? by photochemically reacting a precursor compound of formula (II): Ar—L—Ar? to form a biaryl compound of general formula: Ar—L—Ar?(II)?Ar—Ar? (I) wherein Ar and Ar?, independently of each other, represent an unsubstituted or substituted C6-C20 aryl group or a heteroaryl group with 5-20 ring atoms selected from carbon, nitrogen, oxygen and sulfur, and L represents a group —X—Y—Z— as defined herein. The biaryl compounds are generally suitable as intermediates or key building blocks in a very broad spectrum of organic chemical syntheses and their respective utilities.

Abstract: A peptide siderophore, includes one or more N-nitroso-hydroxylamine ligands. The peptide siderophore can include two side chains, each with a N-nitroso-hydroxylamine ligand, and a further side chain with one or more hydroxy carboxylic acid, hydroxamate, catecholate and/or salicylate ligands. The siderophore can be cyclic. A bacterial cell can express the peptide siderophore, and a composition can include the peptide siderophore, for example in the form of its corresponding iron-complex or bacteria. A method for promoting plant growth, promoting root growth or development, improving stress tolerance in a plant, increasing crop yields of a plant, delivering nitric oxide (NO) to a plant, and/or enhancing chlorophyll production in a plant includes administering the peptide siderophore, bacteria expressing the peptide siderophore or a composition including the peptide siderophore to the plant.

Abstract: The invention concerns four novel secondary metabolites of the Burkholderia rhizoxina endosymbiont, a method for isolating said compounds from cultures of the bacteria and the use of said substances. The invention aims at providing novel rhizoxin derivatives with an antimitotic effect. Therefore, the following substances 1-4 are isolated, said substances exhibiting potential antifungal, cytotoxic and antiproliferative properties.

Abstract: The invention relates to a method for producing rhizoxin and derivates of rhizoxin. The aim of the invention is to produce novel novel micro-organisms that synthesise rhizoxin or derivates of rhizoxin, and to provide a method for producing rhizoxin oder derivates thereof, without the disadvantages of prior art and in a simpler manner with a higher yield. To this end, bacterial symbionts of Rhizopus sp., in the form of Burkholderia Rhizoxina DSM 17360 or other Burkholderia Rhizoxina strains, are isolated, cultivated and used for the fermentive production of rhizoxin and/or derivates of rhizoxin in a submerged culture, and the rhizoxin and/or the derivates thereof are subsequently isolated from the culture supernatant.

Abstract: The invention relates to a method for cleaving cervimycin esters. An object of the invention to convert in a simple manner the cervimycin esters which are less active but formed in larger quantity into the highly active cervimycin K that occurs as a minor component in the preparation by fermentation, is achieved by preparing unesterified cervimycins from cervimycin esters with di- or monomethylated malonic acids, by ester cleavage effected by at least one esterolytic enzyme at temperatures of 20° C. to 75° C. and a pH of pH 5.0 to 10.0, preferably pH 6.0 to 9.0.
