The ability to synthesize antibiotics and exoproteases was studied in 13 species belonging to the Actinomadura genus. The antibiotic and proteolytic activities were found only in A. fulvescens INA-3321 and A. citrea INA-1849. Glycerol was shown to be the best carbon source for the growth and biosynthetic activity of A. fulvescens. A. citrea had a wider spectrum of carbon sources used for the growth and a higher proteolytic and antibiotic activity. A. citrea exerted the maximal biosynthetic activity and the best growth in a medium with starch and xylose. The effect of different nitrogen sources on the growth and biosynthetic activity of A. citrea was also studied.
对属于马杜拉放线菌属的13个物种合成抗生素和胞外蛋白酶的能力进行了研究。仅在微黄马杜拉放线菌INA - 3321和柠檬黄马杜拉放线菌INA - 1849中发现了抗生素和蛋白水解活性。甘油被证明是微黄马杜拉放线菌生长和生物合成活性的最佳碳源。柠檬黄马杜拉放线菌用于生长的碳源谱更广，且具有更高的蛋白水解和抗生素活性。柠檬黄马杜拉放线菌在含有淀粉和木糖的培养基中具有最大的生物合成活性和最佳生长状态。还研究了不同氮源对柠檬黄马杜拉放线菌生长和生物合成活性的影响。
