The outer lipid-containing cell membrane of the gram-negative organisms is par-. Of the gram-positives, 2 are cocci, and the other 4 are rod-shaped (bacilli).. Two of the 4 gram-positive rods produce spores (spheres that protect a dormant bacterium from the harsh environment). Of the gram-negative organisms, there is only one group of gram-negative cocci. The oxygen spectrum of the major bacterial groups.. Often the exact role of the exotoxin is poorly understood..

The structure conferring cell-wall rigidity and resistance to osmotic lysis in both gram-positive and gram-negative bacteria is peptidoglycan, a large, covalently linked sacculus that surrounds the bacterium. In gram-positive bacteria, peptidoglycan is the only layered structure external to the cell membrane and is thick (20–80 nm).

In classifying the antibacterial activity as gram- positive or gram-negative, it would generally be expected that a much greater number would be active against gram-positive than gram-negative bacteria [2]. Therefore, the study of the antibacterial activity of some Indian traditional medicinal plants and the application in edible film has become an important research interest and a big challenge. Wounds are any damage to or break of the skin or underlying tissues.

Cell Walls of Gram-Positive Bacteria In Gram-positive bacteria, the cell exterior is less complex than for Gram-negative cells. Covalently attached to the peptido- glycan layer are teichoic acids, which often account for 50% of the dry weight of the cell wall. A great part of each cell’s uniqueness begins at the cell surface.
