WebApr 25, 2024 · A microbiologist uses chitin staining so she can see fungi clearly under the microscope. Fungi use chitin as structural material in their cell walls so the stain shows the cell wall well. The lactophenol cotton blue stain is the most common stain for fungi. The phenol kills microorganisms and prevents fungal enzymes from breaking down the cell. WebSting definition, to prick or wound with a sharp-pointed, often venom-bearing organ. See more.
