Metabolic products of microorganisms. 263. Nikkomycins SZ, SX, SoZ and SoX, new intermediates associated to the nikkomycin biosynthesis of Streptomyces tendae.
TLDR
New intermediates associated with nikkomycin biosynthesis were isolated and characterized from the culture broth of Streptomyces tendae Tü 901/S 2566, and are analogues to octosyl acids, shunt metabolites of polyoxin biosynthesis.
Biosynthetic capacities of actinomycetes. 2. Juglomycin Z, a new naphthoquinone antibiotic from Streptomyces tendae.
TLDR
A new juglomycin-type antibiotic was identified by a HPLC-diode array screening technique in the culture filtrate of Streptomyces tendae Tü 901/8c by an additional methyl group in position 3 of the naphthoquinone ring system.
The myxocoumarins A and B from Stigmatella aurantiaca strain MYX-030
TLDR
The isolation, structure elucidation and initial biological evaluation of the myxocoumarins derived from this strain are described, which comprise an unusual structural framework and exhibit remarkable antifungal properties.
Optimized nikkomycin production by fed-batch and continuous fermentation
TLDR
High productivity was obtained at slow growth rates in a continuous fermentation process at low dilution rates with and without carbon limitation.
Induction of aerial mycelium formation in a bld mutant of Streptomyces tendae by borrelidin--a macrolide antibiotic.
TLDR
A metabolite, which induced aerial mycelium formation in the bld mutant Tü 901/S 2566-EM 1, was identified by using a HPLC UV/Vis absorbance spectral library and confirmed to be identical with the macrolide antibiotic borrelidin.
