Streptomyces exfoliatus

The poly(HA) depolymerases of the bacteria Alcaligenes faecalis (strains AE122 and Tl), Comamonas acidovorans, Comamonas testosteroni, Comamonas sp., Pseudomonas fluorescens, Pseudomonas lemoignei, Pseudomonas stutzeri, Ralstonia pickettii, Streptomyces exfoliatus, and of the fungi Paecilomyces lilaci-nus, Penicillium funiculosum, and Penicillium pinophilum have been purified and characterized (for details see Table 1). Poly(HA) depolymerases share several characteristics ... 

Quinoid Nematoctonus robustus, Streptomyces exfoliatus Pleurotin, dihydropleurotinic acid, yurinelide [104, 105]... 

Struct, unknown. From Streptomyces exfoliatus. Antibiotic active against gram-positive bacteria. Needles (EtOH). Sol. MeOH, CHCI3 poorly sol. Et20, hexane, H2O. 

The C-ribosyl naphthoquinone exfoliamycin (24) has been isolated from Streptomyces exfoliatus, along with the products of 0-methylation and of elimination of water in ring C. The structure was determined by X-ray crystallography of a derivative the absolute configuration was not determined, but is assumed to correspond with o-ribose. The first synthesis of angucycline antibiotic Cl04 (26) has been accomplished the key intermediate 25 was made by...
