| Popis: | Different carbon sources were utilised in the biosynthesis of oxytetracycline by S. rimosus 93060. Glucose was the best carbon source for antibiotic production in a medium with peptone as the nitrogen source. Two agricultural wastes were used as cheap partial replacements for glucose. The first was Egyptian black-strap molasses. The influence of Egyptian black-strap molasses obtained from different sugar cane manufacturers was tested. Abou-Korkas molasses was the best for the production of oxytetracycline. Potassium ferrocyanide, EDTA and methylene blue were used in the chelation or reduction of inorganic salts present in Abou-Korkas molasses. These materials did not give high titres of oxytetracycline. The suitability of Abou-Korkas molasses was due to its micronutrients. A second substrate tested for antibiotic production was the freeze-dried olive water obtained from the pressing and separation of olive oil. The chemical composition of olive water was investigated. Olive water alone was a poor substrate for antibiotic production, but with glucose it was as effective as molasses. |
