Filtration techniques

DNA depletion is another optional step in the enzyme production process to increase the purity of the product.

Lactosan has three complete fermentation lines which are controlled by a process control system and can be fully sterilised.

Fermentation is followed by a concentration step using a separator.

In the homogenisation step, the biomass is broken down and the enzymes are released. 

In order to increase the purity of the enzyme product or to improve subsequent filtration steps, it is possible to integrate a precipitation step into the production process.

In the enzyme production process, ultrafiltration and diafiltration systems are used to concentrate the product and for buffer exchange respectively.
