Statistical optimization of alkaline lipase production by extreme halophilic archean natrialba asiatica

tailieu.vn

The most common technique for the production of lipases is submerged fermentation (SmF) but solid-state fermentation (SSF) methods can be used also (Gupta et al., 2004. Sharma et al., 2014). incubation, pH of production medium, inoculum source and level can affect the lipase production in both SmF and SSF. (Hasan et al., 2009). Some of the factors influencing the optimal growth of a microorganism not only do not play a role in lipase production but in some cases have a negative effect.

Modeling and simulate alcohol fermentation process by Simulink

tailieu.vn

Ethanol fermentation is widely used in the production of foods like alcoholic beverages. In previous research, the production of ethanol by batch fermentation and continuous fermentation process was examined. For improving the overall fermentation process efficiency, a rigorous analysis to determine optimal values for operation variables is needed. Simulation of the process is a recognized way for doing such an analysis.
