In gram positive bacteria have a peptidoglycan layer outside of the cell wall. Gram negative bacteria have peptidoglycan between membranes.

The natural penicillin have activity against non beta lactamase producing gram - positive cocci, which includes such as - viridans streptococci, anaerobic streptococcus. Penicillin work indirectly bursting bacteria cell walls. It kills bacteria through binding of that betalactum ring.

Gram positive bacteria have a much thicker layer of peptidoglycan and lack of the protection of an outer membrane. This class , penicillin was first antibiotic to be used widely and prevents the final cross linking step. There are some more classes of penicillin like- natural , penicillin-stable, aminopenicillins and extended-spectrum penicillin.

IrinaVladis [17]

A type of glycocalyx called the slime layer is loosely attached to the bacterial cell and protects it from dehydration and loss of nutrients .

<h3>What is glycocalyx ?</h3>

The glycocalyx is a thick outer covering of the plasma membrane .it is of stands of sugars and proteins bound together ,the result is a thick ,sticky layer that helps cells stay put in environments with lots of physical stress .it is a glycoprotein and glycolipid covering that surrounds the cell membranes of bacteria ,epithelial cells and other cells .

Glycocalyx in humans : it is important to both vascular function and the digestive system . your blood vessels actually tiny tubes made of cells .the cells on the very inside of the tube are called endothelial cells and have to withstand the stress of blood flowing over them constantly. endothelial cells produce a glycocalyx which helps leukocytes and thrombocytes stick to blood vessel walls.it is the protective layer of the endothelial cells found in the lumen side of the vessels .

Glycocalyx in bacteria : most of the bacteria produce glycocalyx but some are expert .these expert bacteria make a very thick glycocalyx that helps them to adhere to each other and surfaces in extreme environments .bacteria use the glycocalyx to make thick films of bacteria in nature as well ,called a biofilm .
