LTA, LPS, PG, S. aureus, E. coli, V. harveyi, β-1,3-Glucan

 

Lipoteichoic acid (LTA) is a major constituent of the cell wall of gram-positive bacteria.

 

Lipopolysaccharides (LPS) are found in the outer membrane of Gram-negative bacteria.

 

Peptidoglycan (PG)  is a rigid envelope surrounding the cytoplasmic membrane of most bacterial species. It helps protect bacterial cells from environmental stress and helps preserve cell morphology throughout their life cycle. Peptidoglycan biosynthesis is also an important regulator of bacterial cell division. Since the discovery of penicillin, it has also been an important drug target for antibacterial discovery and development. [1]

 

 

Staphylococcus aureus is a Gram-positive bacteria.

 

Escherichia coli  is a Gram-negative bacteria.

 

Vibrio harveyi is a Gram-negative bacteria.

 

 

β-1,3-Glucan is a major constituent of all of the characterized fungal cell walls, making up between 30% and 80% of the mass of the wall. [2]
