Iodine fixes the crystal violet into the cell wall of the bacteria by working as a mordant. A mordant forms a complex that adheres tightly to the cell... Learn more about this topic: Gram Stain | Purpose, Theory
Gram staining is the technique used to identify Gram-positive and Gram-negative bacteria. In this staining technique, crystal violet is used as a mordant, and alcohol is used as a decolorizing agent. Answer and Explanation: A bacterial smear is prepared to fix the bacteria on the...
Is safranin a basic stain? Basicstains, such as methylene blue, Gram safranin, or Gram crystal violet are useful for staining most bacteria. These stains will readily give up a hydroxide ion or accept a hydrogen ion, which leaves the stain positively charged. Which dye is used for staining ...

Bacteria are single-celled prokaryotic microorganisms found everywhere on earth. Bacteria have many shapes and are very small in size thus cannot be seen with the naked eye.Answer and Explanation: The differences between gram-positive and gram-negative bacteria are: During ...
What are the roles of crystal violet and bile salts in MacConley agar? What are the material properties of the lens? What type of stain is a capsule stain? What are detrivores ? What is parasite load? Describe the process for conducting soil analysis. ...
Bacteria are cellular organisms. They are prokaryotes, which means they lack a nucleus and their genetic material, which is DNA, is not separated from the rest of the cell by a membrane. Bacteria have all of the tools they need to multiply, produce, and store energy. That is why t...
The lactobacillus genus of bacteria is characterized as microaerophilic, gram-positive, and rod-shaped microorganisms that are ecological and metabolically diverse based on phylogenetic analysis data. The lactobacillus highly constitutes the microbiota of humans and various animals, mainly abundant ...
In a laboratory experiment, how can a student better observe that Crystal Violet is a basic stain? A plant is placed in bright sunlight. After a few hours, one of its leaves is stained with iodine solution. Which structure will be stained blue/bl...
Answer and Explanation:1 When iodine comes in contact with starch it becomes bound within the helix of amylose. It then turns a dark blue-black color. The reason that a color...
