Title Statement Oxytetracycline production in coconut water by Patrocinio Sevilla-Santos, A.M. Lozano, L. Santiago, F. Mendoza and D. Rosario Physical Description 113-129 figures, tables Summary, Etc. Oxytetracycline (OTC) was produced on a: very simple novel medium of coconut water. Buffering and corn steep liquor addition increased the antibiotic content to 145 p,g/ml OTC after 5 days of fermentation. The producer. organism is a local streptomyces isolate NIST S-70-24B. The fermentation brew did not exhibit vitamin B12 activity (E. coli factor). The antibiotic was extracted from the brew and identified as oxytetracycline by comparing its physical and chemical properties with the three tetracyclines. A parallel study on chlortetracycline (CTC) production by Streptomyces aureofaciens NRRL 2209 gave a CTC yield of 0.09 p.g/ml after 72 hours of fermentation and a vitamin B12 activity of 0.14 p,g/mL Subject Added Entry - Topical Term Science and technology   Oxytetracycline production -- Coconut water   Oxytetracycline   Fermentation   Streptomyces aureofaciens   Tetracyclines           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
