Monod Kinetics The batch experiment shown in Figure 1 can be repeated by varying initial substrate concentration S over a wide range of valuesresulting in observation of. The resul-ts showed that the fastest growth rate was found at 20 ppt salinity with 0179.

μ kd μnet The cell death rate is sometimes neglected if it is considerably low smaller than the cell growth. Microbial growth kinetics ie the relationship between the specific growth rate μ of a microbial population and the substrate concentration s is an indispensable tool in all fields of microbiology be it physiology genetics ecology or biotechnology and therefore it.

Culture system containing a limited amount of nutrient which is inoculated with the microorganism. The different types of fermentation processes- batch fed-batch semi-continuous and continuous are described above.

Biomass concentration defined in terms of cell dry weight measurements gl or total. The growth kinetics was observed by measuring optical density OD thro-ugh a method of turbidimetry using a spectrophotometer at a wavelength of 625 nm to the stage of death. Fed-batch fermenters are generally operated with the addition of small doses of nutrients therefore the volume of the fermentation broth increases with time.

Batch fermenters generally contain and almost constant volume of broth and a logistic equation has been commonly employed to simulate microbial growth in them. Ln X X 0 ln 2 0693 d. Monod first order and zero order kinetics.

Mass balances were determined with fed-batch fermentation to obtain.
