Enzymes and agricultural biogas production

[Schlattmann]

Do you have any experiences with the addition of enzymes to the AD process, especially for better disintegration of badly digestable fiber materials? Laboratory tests perhaps, relating additional gas yields to the costs of the enzyme? Which enzymes did you test? Or do you know some useful links leading to information?

We have a consulting relationship with LENTIKATS [*LINK*: links are visible after login] on adapting bio-catalysts to our digesters.

Clip from a new release:

"

o amylaceous (cereal) materials (wheat, corn etc.)
o molasses, beet juice and cane
o lignocellulosis materials (straw, bran etc.)
Lentikats Biotechnology is used in the following processes :
o saccharification of hydrolyzed starch solutions (immobilized glucoamylase enzymes)
o invert sugar production from molasses (immobilized invertase)
o fermentation of sugar solutions (immobilized Zymomonas mobilis, Saccharomyces
cerevisiae, Pichia sp., Kluyveromyces sp.)

Advantages:

- reduction of fermentation volumes
- reduced fermentation time
- repeated Lentikats biocatalyst usability
and removal of chemicals and
nutrients required for culture
regeneration and cell growth and dry
yeast deliveries
- elimination of prefermentation
equipment (aeration, pipes,
compressor, etc.)
- decreased energy consumption (less
stirrerers and pumps, etc.)
- higher ethanol yields – 95 %
