✨️Gram test with KOH 3% This is a quick alternative to the traditional Gram staining method. It helps differentiate between Gram-positive and Gram-negative bacteria based on their cell wall properties. Results: 🦠Gram-negative bacteria: The mixture will become viscous and form a sticky thread when lifted with the loop. 🦠Gram-positive bacteria: No change; the solution remains fluid. ✨️Catalase test with H₂O₂ The catalase test determines if bacteria produce the enzyme catalase, which breaks down
