Estimation of Growth & Whole Cell Protein
For estimating growth in terms of whole cell protein [10] 0.5ml of medium was centrifuged at 3000rpm for 10min.
The cell pellet was washed twice with Ringer’s solution and the pellets were resuspended in 1.0ml of 4.6M NaOH to
boiling temperature for 10min to obtain cell free extract protein concentration in cell free extracts was estimated by
[11] method. Growth was also monitored by measuring optical density at 620nm.
