Microbial Degradation of the Ferrichrome Compounds.

An unidentified Pseudomonas capable of growth on ferrichromes as sole sources of carbon and nitrogen was isolated by enrichment culture on ferrichrome A. The spectral shifts observed for the culture supernatant fluids and the degradation products which accumulated in the culture media during growth on these compounds indicated that initially the cyclic peptide rings are broken to yield simpler ...

Microbial degradation of synthetic recalcitrant compounds.

Synthetic compounds, particularly highly chlorinated aromatics, comprise the bulk of the environmental pollutants that somehow must be removed from the environment. Microbial degradation of such compounds is usually very slow, making them highly persistent in nature. Some synthetic compounds, with a lower degree of chlorination are, however, biodegradable; biochemical, genetic, and molecular st...

Microbial hydroxylation of novobiocin and related compounds.

A new soil actinomycete (UC 5762, NRRL 11111) was found to transform novobiocin to 11-hydroxynovobiocin. The product was isolated by solvent extraction and column chromatography, and identified by IR, UV, 1H NMR and 13C NMR spectroscopy. Related structures (8,9-dihydronovobiocin, novobiocic acid and chlorobiocin) were similarly transformed to their corresponding C-11 hydroxylated analogues. The...
