Biology Of E Coli E coli (Escherichia coli) are a small, Gramnegative species of bacteriaMost strains of E coli are rodshaped and measure about μm long and 0210 μm in diameterThey typically have a cell volume of 0607 μm, most of which is filled by the cytoplasm Since it is a prokaryote, E coli don't have nuclei;Characterizing E coli Using a Light Microscope and Gram Staining" from Biotechnology Laboratory Manual by Ellyn Daugherty For more and in sharp focus on 100X before going to 400X, and center and focused on 400X before adding the immersion E coli cells are GramThe slide is stained with safranin for 1min, then rinse with water very gently until no color is coming from the water Blot dry with absorbent paper Place the slide on the microscope to view the sample The grampositive bacteria will stain dark blue or purple The gramnegative bacteria will stain pink In this figure A procedure of Gram stain Photomicrographs Gram stain e coli under microscope 100x
