MICROSCOPIC APPEARANCE Gram Stain: Gram-negative. The microorganism was chosen as a surrogate for a more deadly Rot symptom and pathogenic bacteria (S. marcescens) insolation and identification from rot ginger rhizomes in Chongqing.A ginger rhizome rotted after rhizomes germination (a).The illustration shows the morphology of S. marcescens colonies on NA agar medium (b); a single cell of S. marcescens as observed by SEM at a magnification of 30,000 Other Serratia species are far less common. As a consequence, the colonies are pigmented but the agar remains the standard color. The word marcescens was chosen from Latin for the species name meaning to decay, reflecting the rapid deteriora-tion of the pigment. 25C) and 3 to 14 pH (opt.
