Biofuels Enzymes for a Cleaner World

Growth in population, economics and environmental concerns are among the major driving forces behind the increasing demand for sustainable energy resources. Bioethanol has attained a significant level of popularity as an alternative source of energy. As the bioethanol is mostly produced from starch and sugar containing raw materials.

Enzymatic process in bioethanol production presents an important step in converting complex carbohydrates into simpler sugars. This enzymatic breakdown of biomass facilitates the fermentation process, where microorganisms transform these sugars into ethanol. The utilization of our biofuel enzymes in ethanol production pathway enhances efficiency, reduces energy consumption, and allows for the use of a broader range of raw materials, contributing significantly to the sustainability and viability of ethanol as a renewable energy source.

Alternative and renewable energy sources are the future of a sustainably developed world. Enzyme plays a crucial role in the bioenergy production by facilitating and speeding up the chemical reactions involved in breaking down complex organic materials into simpler components that can be converted into usable biofuel.

Fuel Ethanol Production
Fuel Ethanol Production

Our premium enzymes for bioenergy are pivotal in the production of fuel ethanol from biomass through a process called biofuel enzymatic hydrolysis. This process involves breaking down complex carbohydrates in biomass, such as cellulose, a major component of plant cell wall, into simple sugars like glucose and xylose. These sugars are then fermented by yeast or bacteria to produce ethanol.

Pretreatment of Biomass

Before enzymatic hydrolysis, the biomass needs to undergo pretreatment to make it more accessible to enzyme. This process involves physical, chemical, or biological treatments to break down the lignocellulosic structure of the biomass, making it easier for enzyme to act on.

Enzyme Hydrolysis

Once pretreated, enzymes are introduced to the biomass. Cellulase breaks cellulose into glucose, and hemicellulases break down hemicellulose into sugars like xylose and mannose, acting as catalysts to expedite the breakdown of complex polysaccharides into simpler sugars.


The resulting sugar mixture obtained from enzyme hydrolysis is fermented by yeast or bacteria. The microorganisms metabolize the sugars, primarily glucose and xylose, converting them into ethanol and carbon dioxide through the process of fermentation.

Food Grade Brewing Alcohol Production
Food Grade Brewing Alcohol Production

In food-grade brewing alcohol production, our biofuel enzymes are used to facilitate the breakdown of complex carbohydrates in raw materials, such as grains like barley, corn, wheat, or rye, into simpler fermentable sugars. Our superior biofuel enzymes are used in the brewing process, aiding in optimizing the efficiency of the brewing process by extracting the fermentable sugars from the grains. Their precise action and specificity ensure a consistent and high-quality yield of alcohol, meeting the standards required for food-grade production.


The process typically begins with mashing, wherein grains are ground and mixed with hot water to create a mash. Biofuel enzyme, such as our α-amylase, is added at specific temperatures to break down the complex starches present in the grains into simpler sugars, such as maltose.


Our glucoamylases are employed during saccharification to further convert the remaining complex sugars into easily fermentable sugars. This step ensures maximum sugar extraction from the mashed grains.


The resulting sugar-rich liquid, known as wort, is cooled and transferred to fermentation vessels. Yeast is added to the wort, which then consumes these fermentable sugars, producing alcohol and carbon dioxide as byproducts. This fermentation process, driven by the biofuel enzymes' action on the grain-derived sugars, yields the desired alcohol content.
