PROJECT TITLE:
New sol-gel-magnetic biocatalysts used for the enzimatic hydrolysis of lignocellulosic biomass
Noi biocatalizatori sol-gel-magnetic utilizati pentru hidroliza enzimatică a biomasei lignocelulozice
ACRONYM: BIOCATLIGNOCELL
PROJECT COORDINATOR: Politehnica University Timişoara

BUDGET: 431.900 RON (Public budget)
START TIME: 15/09/2020
END TIME: 14/09/2022

PROJECT LAYOUT
The major cause of environmental pollution is due to emissions generated by burning of fossil fuels. The known crude oil reserves are going to disappear in short time and the oil crisis in recent years, together with the rising of air pollution levels has shown the need for the replacement of fossil fuels with cleaner biofuels, obtained by processing a range of organic renewable raw materials. The first step in conversion of lignocellulosic biomass to bioethanol is the pretreatment for the release of cellulose from the network formed with lignin and to increase the yield of fermentable sugars. There are many methods of pretreatment, but they are energy consumable and pollute the environment.
In this sense the project proposes an innovative approach on studies regarding biomass pretreatment and enzymatic hydrolysis of cellulose in an integrated system that can improve the exploitation of biomass components and the reuse of the biocatalyst. It is desired to provide novel biocatalysts, immobilized cellulases customized by new sol-gel entrapment techniques, used in the hydrolysis of certain types of lignocellulosic biomass. By immobilization, stability and reusability of cellulases are significantly improved, a key issue for increasing the amount of fermentable sugars and to reduce process costs.
