Phase-Contrast Microscopy for Evaluating Developmental Mutants in <i>Streptomyces</i>

Source: Bennett, J. A. et al. Visual and Microscopic Evaluation of Streptomyces Developmental Mutants. J. Vis. Exp. (2018)This video demonstrates the use of phase-contrast microscopy to examine phenotypic differences between wild-type and mutant Streptomyces coelicolor. It outlines the steps involved in preparing and imaging aerial filaments to detect developmental defects in spore formation.
