โœฆ Synopsis

Corn-cob was used as a substrate in the production of oxytetracycline by Streptomyces rimosus TM-55 in a solidstate fermentation. Oxytetracycline was detected on day 4, and reached its maximum on day 8. Optimal conditions for oxytetracycline production were an initial pH of 5.2 to 6.3, an initial moisture content of 64% to 67%, supplementation with 20% (w/w) rice bran or 1.5% to 2.5% (w/w) (NH4)2SO4 as sole N source, 1.0% (w/w) CaCO3, 2% (w/w) MgSO4.7H2O, and 0.5% (w/w) KH2PO4, with incubation for 8 days at 25 to 30ยฐC. Each g substrate produced 7 to 8 mg oxytetracycline.

During oxytetracycline production by Streptomyces rimosus TM-55 on sweet potato residue in a solid-state column reactor, the moisture content increased by between 2 and 5% (w/w) during incubation, from an initial content of 70 to 73%, and pH initially increased from 6.0 to 7.3, followed by a gradual
