The production of neomycin by the actinomycete Streptomyces fradiae, under semi-solid-state fermentation conditions was the main subject of this study. Two supports (nylon sponge and orange peelings) were tested in order to determine the most suitable one for the production of neomycin by the above-mentioned microorganism. Nylon sponge led to the highest neomycin production, reaching a maximum value of 13,903 mu g/mL on the 10th day of cultivation. As a control, the same experiment was performed under submerged fermentation (SmF) conditions, without solid support. Here the production of neomycin by S. fradiae was about 55-fold lower (i.e. 250 mu g/mL) than that obtained for SSF. (C) 2013 Elsevier B.V. All rights reserved.
