Preparation and Isolation of Streptomyces venezuelae Spores from a Liquid Culture

Source: Schlimpert, S., et al. Fluorescence Time-lapse Imaging of the Complete S. venezuelae Life Cycle Using a Microfluidic Device. J. Vis. Exp. (2016)This video demonstrates the cultivation and isolation of spores from Streptomyces venezuelae. Spores, dormant cells that help bacteria survive stress, are produced during nutrient limitation and collected through centrifugation. The method ensures a pure, cold-stored spore suspension for downstream applications.
