Kinetic Growth of Saccharomyces cerevisiae in Non Dairy Creamer Wastewater Medium

Efforts in non dairy creamer (NDC) wastewater treatment can be performed by converting it into raw materials, i.e. as a medium for microorganisms growth. This research had an objective of examining the growth kinetics of Saccharomyces cerevisiae in the fermentation of the non dairy creamer wastewater for protein production. Kinetic study of the growth and fermentation is necessary as an introduction to understanding each process of the fermentation. The research applied an Experimental Design with a full factorial design. Treatments during the experiment consisted of P1 (NDC medium concentration of 25%), P2 (NDC medium concentration of 50%), P3 (NDC medium concentration of 75%), and P4 (NDC medium concentration of 100%). The cellular concentrate intakes were 105, 106, 107, and 108 cell/ml. The experiment resulted in specific growth rate (μ) of 0.240868 (hour-1), maximum specific growth rate (μmax) of 55.7479 (hour-1), with the highest protein contents of 22.15 mg/l at the concentration medium of 75%.
