BTEX compounds such as benzene are frequent soil and groundwater contaminants that are easily biodegraded under oxic conditions by bacteria. In contrast, benzene is rather recalcitrant under anaerobic conditions. The analysis of anoxic degradation is often hampered by difficult sampling conditions, limited amounts of biomass and interference of matrix(More)
Empedopeptin is a natural lipodepsipeptide antibiotic with potent antibacterial activity against multiresistant Gram-positive bacteria including methicillin-resistant Staphylococcus aureus and penicillin-resistant Streptococcus pneumoniae in vitro and in animal models of bacterial infection. Here, we describe its so far elusive mechanism of antibacterial(More)
Lipopeptides (LPs) are a structurally diverse class of amphipathic natural products that were in the past mainly known for their surfactant properties. However, the recent discovery of their antimicrobial and cytotoxic bioactivities have fueled and renewed the interest in this compound class. Propelled by the antimicrobial potential of this compound class,(More)
The plant microbiome represents an enormous untapped resource for discovering novel genes and bioactive compounds. Previously, we isolated Pseudomonas sp. SH-C52 from the rhizosphere of sugar beet plants grown in a soil suppressive to the fungal pathogen Rhizoctonia solani and showed that its antifungal activity is, in part, attributed to the production of(More)
Saccharothrix espanaensis is a member of the order Actinomycetales. The genome of the strain has been sequenced recently, revealing 106 glycosyltransferase genes. In this paper, we report the detection of a glycosyltransferase from Saccharothrix espanaensis which is able to rhamnosylate different phenolic compounds targeting different positions of the(More)
Within the framework of our genome-based program to discover new antibiotic lipopeptides from Pseudomonads, brabantamides A-C were isolated from plant-associated Pseudomonas sp. SH-C52. Brabantamides A-C displayed moderate to high in vitro activities against Gram-positive bacterial pathogens. Their shared structure is unique in that they contain a(More)
