7. What is a Lentikats Biocatalyst? Unique shape of the matrix and the original principle of immobilisation enable the encapsulation of free enzymes or microorganisms (bacteria, yeasts, fungi) in a stable porous PVA (polyvinylalcohol) carrier. The carrier advantages are: Excellent physical-mechanical characteristics that provide for long-term mechanical stability Low biodegradability Zero toxicity Lentikats Biocatalyst enables easy separation of enzymes and microorganisms from the surrounding media and therefore it can be reused multiple times. Biotechnologies are changing the world…

10. Lentikats Biocatalyst Advantages of using PVA as a matrix for encapsulation: inexpensive, non-toxic polymerization under optimal conditions, cell conservation enables creationof hydrogels with excellent mechanical properties no side effects in processes large capacity for cell building easily supervised processes stable processes easy separation from ambient media

11. How does Lentikats Biocatalyst function? Due to its maximum surface and at the same time minimum volume of the Lentikats Biocatalyst, the diffusion limitations associated with the transport of the substrate into the lens and the product out of the lens are significantly reduced.

12. What are the advantages of Lentikats Biotechnology over traditional technologies 1) Higher biomass concentration Reduced volume of reactors Reaction rate Investment costs saving Biomass concentration 100 € 100 € 100 € 100 € Operational costs saving (electricity, heat, etc.) Higher yields

13. What are the advantages of Lentikats Biotechnology over traditional technologies 100 € 100 € 2) Easy separation from bulk media 100 € 100 € Operational costs saving Repeatable use of Biocatalyst 1 – medium inlet, 2 – medium outlet, 3 – Lentikats biocatalyst fill inlet, 4 – Lentikats biocatalyst discharge, 5 – sieve separator, 6 – medium with Lentikats biocatalyst, 7 – separated medium Lower production of waste and by-products 3) Robustness towards environmental shocks profound change of pH level higher concentration of toxic compounds Applicability under extreme or stress conditions
