The yeast budscars are extremely interesting structures and can be visualized using the SPM. The budscars are structurally very strong materials and very difficult to break apart. Yet, once buds are formed, they easily separate and the bud scar area is repaired immediately.  The yeast cell wall mainly consists of polysacharrides such as mannans(30%) and glucans(30%). The bud scar is made up of a ring of Chitin(15%).  Chitin is resistant to microbial degradation. Medical sutures are made of Chitin because of the properties of strength and flexibility. After a wound heals, the chitin sutures decompose naturally. So there is no necessity to remove chitin threads. Cellulose is the structural component of cell walls. It is made up of long chains of glucose molecules. Once the yeast buds are separated from the parent cell, the bud scars are formed immediately. This is useful in genetic engineering.
