Mannanases, one of the important enzyme group for industry, are produced by numerous filamentous fungi, especially Aspergillus species with different fermentation methods. The aim of this study was to show the best fermentation method of β-mannanase production for fungal growth in fermenter. Therefore, different fermentation strategies in fed-batch fermentation (suspended, immobilized cell, bio...

A system capable of handling a large volumetric gas fraction while providing a high gas to liquid mass transfer is a necessity if the metanotrophic bacterium Methylococcus capsulatus is to be used in single cell protein (SCP) production. In this study, mixing time and mass transfer coefficients were determined in a 0.15 m3 forced flow U-loop fermenter of a novel construction. The effect on the ...

The grape must temperature management in a fermenter tank is fundamental to guaranty high-quality wine. fermentation an exothermic process and good cooling system tanks required. However, for reducing costs increasing the efficiency of operation, passive device based on heat pipe technology was proposed. Since its thermal sizing necessarily be accurate allow correct product during fermentation,...

This work deals with systems whose dynamics are affine in the control input. Such considered to be significantly differentially expressed a canonical form, namely quadratic (pseudo) port-Hamiltonian representation, order explore further some structural properties usable for tracking-error passivity-based design. Different kinds of linear and nonlinear engineering including an open isothermal homoge...
