Pili: structure/function
• Synonymous with fimbrae, fibril, filament
• Structures are something of a mystery still
• Function? Media attachment, one way or other– To surfaces– To other cells – animal or microbial– Often lost upon culturing in broth

Glycocalx
• S-layer
• Capsule/slime layer
• Functions:– Stealth– Hydration– Nutrients– Attachment

Cell Wall
• Functions– Protection– Transport– Many more if you include the periplasmic
space
• Cell Wall Varieties
