This paper deals with the integration of different types of standardised and available fieldbus and sensor/actuator bus systems into control systems and applications. The concept for integration and the first steps of realisation considering the bus

New concepts for the control of machine tools frequently require increased integration of sensors and measurement systems. The requirements for process monitoring and control demonstrated by autonomous manufacturing cells, such as those which are now

Perhydroderivatives of polyene antibiotics have a much lower activity against eukaryotic cells than the polyene antibioitics itself. Bacterial cells are normally resistant against most polyene antibiotics and their perhydroderivatives. In earlier exp

Using a strain of Streptomyces hygroscopicus JA 6599 several 14C-compounds were investigates as potential precursors of the macrolide antibiotic turimycin followed by partial degradation to localize the radioactivity. L-Methionine-14C-methyl and n-bu

The complete assignment of 13 C and 400 MHz proton NMR spectra provides corroboration for earlier structural proposals for tetramycin (tetramycin A), a tetraene macrolide antibiotic, and settles the structure of tetramycin B, a newly isolated congene

The nourseothricin producer Streptomyces noursei is resistant to its own antibiotic in submerged as well as in surface culture. The strain shows no cross-resistance to miscoding inducing aminoglycoside antibiotics. Cell free extracts of Streptomyces

The structure of the tetraene antifungal antibiotic tetramycin has been established by detailed studies of mass, 1 H and 13 C NMR spectra as well as by chemical degradation. A newly developed mass analysis has been introduced for determining the carb
