Gluconimycin,a new antibiotic

Summary A new antibiotic, gluconimycin, was isolated from Streptomyces AS 9. The systematic position of the organism is discussed. Gluconimycin has a polypeptide nature. It contains iron and gluconic acid in its molecule. Thus it has been classified as a member of sideromycins. Gluconimycin is considered from the fast moving type when chromatographed by butanolacetic acid-water. The antibiotic is active against Gram+ve, Gram-ve bacteria and some fungi. The antibiotic exerts high toxicity when injected in mice.
