Four further antibiotics related to olivanic acid produced by Streptomyces olivaceus: fermentation, isolation, characterisation and biosynthetic studies.

Four beta-lactam antibiotics with beta-lactamase inhibitory activity MM 22380, MM 22381, MM 22382 and MM 22383 containing the carbapenem nucleus have been isolated from a culture of Streptomyces olivaceus ATCC 31365. Fermentation conditions for their production and methods for their isolation are described. Evidence for a biosynthetic link between these compounds and the previously described ol...

mycin, N-acetylthienamycin and N-acetyldehydrothienamycin from S. cattleya7) and also a group of antibiotics, the epithienamycins A - D from S. flavogriseus.8,9) The olivanic acid derivatives

Streptomyces olivaceus ATCC 31365 produces a family of novel 1S-lactam antibiotics collectively referred to as the olivanic acids. Seven such compounds, MM 4550, MM 13902, MM 17880, MM 22380, MM 22381, MM 22382 and MM 22383 have been identified which have the same carbapenem nucleus but with different side chains attached to the nucleus. The compounds with an (8S) hydroxyethyl substituent and c...

Radio-mm-FIR Photometric Redshifts for (sub-)mm Galaxies

We present a comparison between the published optical, IR and CO spectroscopic redshifts of 86 (sub-)mm galaxies and their photometric redshifts as derived from long-wavelength (radio–mm–FIR) photometric data. The redshift accuracy measured for 13 sub-mm galaxies with at least one robustlydetermined colour in the radio–mm–FIR regime and additional constraining upper limits is ∆z ≈ 0.30. This ac...
