Autoradiographic study of hyphal growth during aerial mycelium development in Streptomyces antibioticus.

摘要

The pattern of growth of aerial mycelium in Streptomyces species was investigated by autoradiography. Colonies of Streptomyces antibiotics were labeled with N-acetyl-D-[1-3H] glucosamine to localize the sites of hyphal growth during the development of aerial mycelium. Autoradiographs obtained with sections of the colonies revealed that hyphal growth occurs not only at the top of the colony but also in the inner zones of the aerial mycelium.
