The impact of Schiff bases on antibiotic production by Streptomyces hygroscopicus

Abstract

A media consisting of isatin-Schiff bases (isatin-3-thiosemicarbazone, isatin-3-semicarbazone, and isatin-3-phenylhydrazone) was developed to maximize the production of antibiotics Hexaene H-85 and Azalomycine B by Streptomyces hygroscopicus. The media isatin-3-thiosemicarbazone resulted in the maximum antibiotics concentration of 372 μg cm-3 for Hexaene H-85 and 118 μg cm-3 for Azalomycine B. The impact of modified media on soil morphology also was investigated. © The Author(s) 2009.
