How do the characteristics of gram positive and gram negative bacteria compare and contrast with each other?
Oh, dude, gram-positive bacteria have this thick peptidoglycan layer that stains purple with that crystal violet dye, while gram-negative bacteria have this extra outer membrane that makes them stain pink with safranin. It's like one is all about the purple life, and the other is like, "Nah, I'm feeling pink today." So yeah, they're basically just bacteria with different fashion senses.

ReneGram positive bacteria have a thick layer of peptidoglycan in their cell walls, which retains the purple stain in the Gram staining process. They also lack an outer membrane. In contrast, gram negative bacteria have a thinner layer of peptidoglycan and an outer membrane that can make them more resistant to antibiotics. Additionally, gram negative bacteria appear pink after the Gram staining process.
Ah, gram positive and gram negative bacteria are like different colors on our palette. Gram positive bacteria have a thick layer of peptidoglycan in their cell wall, giving them a purple color when stained. On the other hand, gram negative bacteria have a thin layer of peptidoglycan and an outer membrane, which gives them a pink color when stained. Both types play important roles in the beautiful tapestry of life.

Are coliforms gram-positive or gram negative?
Coliforms are typically gram-negative bacteria, characterized by their ability to ferment lactose. However, some coliform bacteria can exhibit varying characteristics, including gram-positive features.
What bacteria is indole negative urea positive methyl red positive hydrogen sulfide positive and lactose negative?
Proteus vulgaris is a bacterium that fits this description. It is indole negative, urea positive, methyl red positive, hydrogen sulfide positive, and lactose negative. These characteristics are used in biochemical tests to help classify and identify different bacteria species.
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Is acid fast bacteria gram positive or negative?
Acid-fast bacteria are gram-positive.
