The preliminary studies of natural rubber serum (NRS) as a protein source for lactate fermentation

In the initial stage of the study, the effects of the different shaker speeds (l 00 rpm, 150 rpm and 200 rpm) in Ethanol Coagulation method were investigated. The result shows that there are no significant different between three volumes, however the brightness of the serum shows that 200rpm was s...
