Role Of Enzymes in Biotechnology, 1. The main role of enzyme is used to develop culture. 2. Enzymes are used in the preparation of medicines as well as for food preservations.
FBS provide amino acids for the cell growth
in co2 incubators, the co2 reacts with h2o in the medium to generate hco3- which acts as a buffering system for the cells in the medium. 5% co2 is the optimum concentration for the maintenance of the ph.
Glucose is an essential component and a carbohydrate source that facilitates the growth of cells.
Callus stageTissue is grownin nutrient medium till it forms an unorganised mass called callus.Plantlet stageThe callus is transferred to another medium for growth and differentiation, that forms plantlets.Maturity stageThe plantlets are transplanted into soil or pots where they grow to maturity.
It is used to buffer the medium (there is some phosphate buffer in medium too). the carbonate/hydrocarbonat buffer in medium is in equilibrium with the CO2 in the incubator (usually set on 5%)
It is the medium which contains all the required enriched nutrients essential for the cells to survive in invitro condition.
