There are three principal factors that determine fermentation activity and results: Yeast, Wort Nutrients and Temperature. In any microbial fermentation, it is necessary not only to measure growth and product formation but also to control the process by altering environmental parameters as the process proceeds. The temperature is a variable that directly affects the growth rate of the microorganisms (Charoenchai et al.,1998), and the final composition of wine (Torija et al., 2003). For a successful fermentation, the fungus must behave in a consistent, predictable manner, giving similar growth rates and metabolite yields in successive fermentations. of India) Project on - Creation of e-Contents on Fermentation Technology Project control No: RE-02091011297, Christ College, Rajkot, Gujarat, India Module-3: THE COMPONENT PARTS OF A FERMENTATION PROCESS Any fermentation process can be divided under three stages A.

A crucial factor in achieving this is to provide a nutrient medium that contains utilizable sources of carbon, nitrogen and other essential elements in the appropriate amounts and ratios. Definition of Respiratory Quotient: It is the ratio of the volume of CO 2 produced by the volume of O 2 consumed (i.e., CO 2 /O 2) during a given time.  Inner yeast cell released components - released from the yeast cell when it is inactive. This process is best known when yeast is used to produce alcohol from mash or when it is used in dough to make bread rise. Several factors impact the initiation and progression of the malolactic fermentation. Minor components include inorganic salts, vitamins, growth factors, anti-foaming agents, buffers, dissolved oxygen, other dissolved gases, growth inhibitors and enzymes.
