Benefits of technology

The patent text describes methods for producing fermentation products from starch-containing material using a fermenting organism. These methods involve converting starch to fermentable sugars, fermenting the sugars with a microorganism to create a mash, and then using an enzyme composition containing a xylanase and a pectinase. This results in a more efficient process for producing fermentation products.

Problems solved by technology

A vast number of commercial products that are difficult to produce synthetically are today produced by fermenting organisms.
Ethanol plants have struggled to maintain profitability, which is highly variable depending upon corn price, demand and price of DDGS, tax credits, gasoline consumption, ethanol exports, and changes to the Renewable Fuels Standard (RFS) mandates.

[0088]In one embodiment, the process of the production of ethanol from corn was performed as follows:

[0089]A) Process for Producing Fermentation Products

[0090]a) Reducing the particle size of the starch-containing material by milling[0091]corn (Company Pannonia, Hungary) was milled to

[0092]b) Forming a slurry comprising the starch-containing material and water[0093]1.5 kg milled corn was added to 4.96 L ml warm tap water (water hardness 3.57 mmol / L) at 35° C. to obtain a 25% solid solution with a final volume of 6 L in a Biostat C fermentor (company Sartorius) leading to a pH of about 5.6.

[0094]c) Liquefying of the starch-containing material[0095]temperature was increased to 90° C.[0096]1 ml α-amylase “α-amylase VF-Kartoffel” (Schliessmann, Nr. 5049) was diluted in 10 ml tap water and then the diluted amylase was added to the slurry[0097]temperature was increased to 90° C.[0098]the fermentor was incubated for 90 min at 90° C. and 450 rpm[0099]the slurry was cooled to 30° C., pH was...

Abstract

The present technology relates to methods of producing a fermentation product from starch containing material, wherein the fermentation medium is subjected before, during and / or after the fermentation process to an enzyme composition comprising a xylanase and a pectinase.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to improved processes of producing fermentation products from starch-containing material using a fermenting organism.BACKGROUND OF THE INVENTION[0002]A vast number of commercial products that are difficult to produce synthetically are today produced by fermenting organisms. Such products include alcohols (e.g., butanol, ethanol, methanol, 1,3-propanediol); organic acids (e.g., acetic acid, citric acid, gluconate, gluconic acid, itaconic acid, lactic acid, succinic acid, 2,5-diketo-D-gluconic acid); ketones (e.g., acetone); amino acids (e.g., glutamic acid); gases (e.g., H2 and CO2), and more complex compounds, including, for example, antibiotics (e.g., penicillin and tetracycline); enzymes; vitamins (e.g., riboflavin, B12, beta-carotene); and hormones. Fermentation is also commonly used in the consumable alcohol (e.g., beer and wine), dairy (e.g., in the production of yogurt and cheese), leather, and tobacco industries.[0003...
