Enzymes as biocatalysts in biogas facilities

BC.ZYM products accelerate processes in the fermenter

BC.ZYM provides enzyme products specially optimised for fermentation biology using renewable raw materials.

They activate conversion processes in the biogas fermenter using fibrous substrates, and function as biocatalysts. The choice of the different product variants is analysis-based.

The enzyme product BC.ZYM

This specific enzyme product line activates the conversion processes in your fermenter when using fibrous substrates and when trace element status is optimal.

The effect of enzymes in fermentation biology

The BC.ZYM products are specific biocatalysts which accelerate or enable biochemical reactions.

During the first step of biogas generation, called hydrolysis, the enzymes convert the substrate components (cellulose, hemicellulose, pectins, starch, proteins, lipids) into cell membrane-permeating substances (sugars, amino acids, fatty acids).

Only then can the bacteria involved in the biogas process perform the subsequent stages of biogas generation.

BC.ZYM provides the enzymes specifically optimised for these processes. This latest innovation in the development of enzyme mixtures solves a multitude of specific difficulties encountered in biogas facilities.

Use of different BC.ZYM products

Use recommendation

difficulties in mixing fermenter contents
difficulties in pumping fermenter contents
suboptimal substrate utilisation
a high volume of fibrous materials
floating or settled biomass a short dwell time
treatment of the fermentation residue after separation, with subsequent recirculation into the fermenter

Analysis of the substrate

Before using the products an enzyme activity test is conducted on your substrate in the biogas laboratory Wahlstedt, followed by a recommendation on the most suitable product for your needs. The appropriate product variant is selected depending on the composition of the substrate. The BC.ZYM products are supplied in fermentable bags.

Dosing: 1 – 3kg/100 kW depending on enzyme activity test

BC.ZYM M for maize silage and whole-crop cereal silage

BC.ZYM G for grass and clover grass silages

BC.ZYM D for the treatment of material pressed from fermentation residues prior to recirculation into the fermenter

Use of the BC.ZYM products

BC.ZYM increases the generation of electric energy

Field results confirm the data obtained in the laboratory. BC.ZYM increases the generation of electric energy. After discontinuing BC.ZYM the electricity yield drops. The feed volume has to be increased.
