Abstract
Respiration activity was located in Streptomyces ambofaciens using formazan crystals and image analysis. The technique was validated by comparing it to a global respiration rate measurement method. A uniform distribution of formazan crystals along the hyphae was found in cultivations in flasks and fermenter, throughout the cultures, although respiration is globally decreased when cultures age.
