Abstract
The growth of filamentous antibiotic productive bacteria Streptomyces ambofaciens in submerged culture is monitored via analysis of light microscopy images. The method provides data on the size of the microorganisms and classifies their morphological types into three populations: single filaments, entangled filaments and pellets. Two different growth media are studied, the first one contains valin which is a precursor of the antibiotic (spiramycin) and the second contains an ammonium salt as nitrogen source. Both kinetics of the distribution in number and in projected area of the morphological types during the fermentation are obtained.
