Bioethanol/Alcohol:

The product assortment offers the best possible options for the efficient liquefaction and saccharification of soluble starch solution and offers unparalleled enzymes to achieve a fast viscosity reduction in the production process.

Liquefaction:
For liquefaction the WeissBioTech markets the Fuelzyme® E alpha-amylase being the best alpha-amylase enzyme-preparation available in the market.
Fuelzyme® E alpha-amylase provides incomparable mash viscosity reduction, at a much lower dose, over competitive products.
The enzyme is designed to significantly improve the efficiency and economics of ethanol production.
The product benefits of Fuelzyme® E alpha-amylase are:
  * Exceptional viscosity reduction
  * Increased throughput
  * Broad pH liquefaction
  * Extraordinary thermal stability
  * No calcium required
  * reduced sulphuric acid use

The assortment further carries
Deltazym® BAA: a bacterial alpha-amylase for use in processes working at neutral pH-conditions (ph 67) and at moderate temperatures of up to 80-90C.

Deltazym® HSAA CT: a heat stable alpha amylase for use in processes working at pH-conditions of 58 and at high temperatures of up to 8595C.

The WeissBioTech products for Saccharification have an increasingly good track record:
Deltazym® GA L-E5: is a specialty glucoamylase derived from A. niger with excellent side activity profiles yielding its very good performance at 62 C and pH 4,24,6 when compared to the many equivalent commodity products.
When combined with the superior performance of the Fuelzyme® E alpha-amylase, the use of Deltazym® GA L-E5 leads to an improved alcoholic yield at the subsequent ethanol fermentation.

Recently breakthroughs in Viscosity reduction have been achieved with the introduction of Deltazym® VR VX.

This liquid product contains an innovative and highly thermostable fermentation produced xylanase (Endo-1,4- glucanase, EC 3.2.1.4) and has been developed from the very extensive range of novel enzyme products of Verenium.
The product performs at pH 4.08.0 and at temperatures up to 80C. The optimum conditions of use are at pH 4.56.0 and a temperature from 4570C. At this level the performance of Deltazym® VR VX is unmatched by any other viscosity reducing enzyme on the market.

For less demanding applications, WeissBioTech offers:
Deltazym® VR DP-10 a hemicellulose with an excellent side activity profile for use in viscosity reduction operations, always within wheat, soy or starch processing applications. The pH optimum lies between 4,5-5 and the optimum temperature range are 6065C.

Deltazym® VR DD-800 is a Trichoderma longibrachiatum-produced Endo--glucanase to enhance viscosity reduction pre- and post liquefaction during the production of bio-ethanol. The product contains cellulase-, hemicellulase-, xylanase- and
pentosanase- side activities as well and operates at optimum conditions: pH 3.5 5.5 and temperatures up to 65 C

The Deltazym® VR XL is a Trichoderma longibrachiatum-produced Xylanase
to enhance viscosity reduction during wheat and cereal processing during the production
of bio ethanol. The product also contains hemicellulase- and glucanase side activities.
The product has been especially developed for its contribution in viscosity reduction during
the processing of wheat and other cereals in the production of alcohol and for its high
efficacy at a relatively low pH. The optimum conditions of use are: pH 4.55.0 at 5060C.

The WeissBioTech product assortment is further extended with a series of specialty protease enzymes (Deltazym® BNP and Deltazym® APS) tailored for specific applications

For the alcoholic fermentation, WeissBioTech offers the specially selected Saccharomyces cerevisiae Yeast under the name of DELTAFERM® AL-18 and DELTAFERM® AL-69.
