Types of Industrial Enzymes

There are various types of industrial enzymes that are utilized across different industries for various applications. Some of the major types are:

- Carbohydrases: These enzymes help in breaking down carbohydrates and sugars. Some important carbohydrases used industrially include amylases for starch breakdown, cellulases for cellulose hydrolysis, and invertase for sucrose hydrolysis.

- Proteases: Proteases or proteolytic enzymes help in protein hydrolysis. They are used widely in food processing, animal feed, detergents etc. Important industrial proteases include trypsin, pepsin, papain etc.

- Lipases: Lipases help in fat and oil modification processes. They are used for hydrolysis, interesterification and rearrangement of fats and oils. Important lipases include those from Candida rugosa and Pseudomonas.

- Polymerases: Enzymes like DNA and RNA polymerases are important for molecular biology applications in research and diagnostics.

- Oxidoreductases: These catalytic enzymes bring about oxidation or reduction of substrates. Glucose oxidase, lactate oxidase, lipoxygenase etc. find industrial uses.

- Lyases: Enzymes like pectin lyase and cellulose lyase show lyase activity by hydrolyzing various chemical bonds.

- Isomerases: Enzymes like glucose isomerase and amino acid racemases catalyze structural changes in molecules through isomerization.

Major Industrial Application Areas

Some key industries that utilize Industrial Enzymes on a large scale are:

- Food Processing: Enzymes play a crucial role in food processing for activities like baking, brewing, cheese production, juice/wine making and more. Amylases, lipases, proteases etc. are extensively used.

- Animal Feed: Proteases and phytases are added to animal feeds for better nutrient digestibility. This improves feed conversion efficiency.

- Textile Processing: Cellulases and lipases are added during finishing steps like desizing, bio-polishing and dye removal in textile processing.

- Detergents: Proteases and lipases are formulation constituents that help remove tough stains. Amylases also aid in starch removal.

- Leather Processing: Enzymes like proteases facilitate soaking, dehairing, bating and liming reactions in leather processing.

- Pulp & Paper: Xylanases and cellulases are used for pulp bleaching, de-inking of recycled paper and improves paper properties.

- Biofuels: Amylases, cellulases and lipases are employed for breaking down starch, cellulose and oils to fermentable sugars for bioethanol production.

- Pharmaceuticals: Important therapeutic enzymes and industrial platforms for research rely on enzyme action. Proteases/peptidases also aid drug development.

In the following sections, some key industrial application areas of enzymes are discussed in further detail.

Food Processing

The food industry sees one of the largest applications of industrial enzymes. In bakery, amylases are added to dough to break down complex starches into simpler sugars. This enhances the qualities like texture, volume and shelf-life of bakery products.

Proteases find use in cheese production for milk coagulation and development of flavor profiles in different cheese varieties. Lipases contribute to the taste and aroma of many food items like chocolate, dairy and baked goods.

Brewing beer relies on enzymatic action of amylases on malted barley to generate fermentable sugars from starch. Other fermentation based industries like wine-making also employ pectinases, beta-glucosidase and cellulose enzymes.

Fruit and vegetable processing utilizes amylases, pectinases and cellulases for extraction of juices with better yields, clarity and stability. Proteases aid in tenderizing meat. Together, enzymes play a major role in food manufacturing globally.

Detergents

Enzymes have gained popularity as formulation ingredients in detergents due to eco-friendly chemical-free cleaning. Proteases are the primary workhorses that break down proteins from various stains like blood, dirt, food etc during wash cycles.

Amylases remove starchy soils while lipases dissolve fats and oils. Combined together through tailored detergent formulations, enzymes support high temperature and low temperature washing even in hard water conditions.

Additionally, cellulases and hemicellulases aid in removing embedded stains on fabrics. This has allowed transition to lower wash temperatures thereby saving energy. Enzymes are thus critical components that improve cleaning efficiencies of detergents sustainably.

Animal Feed

The animal feed industry leverages specific enzymes to enhance feed digestibility, nutrient absorption and performance metrics in poultry and livestock. Phytases help liberate phosphorus locked in plant-based feed ingredients like seeds that would otherwise not be bioavailable to animals.

Proteases break down protein into amino acids allowing more complete breakdown and utilization. Xylanases aid in breaking down non-starch polysaccharides improving overall energy values. This translates to better feed conversion ratios, higher growth rates and improved returns for farmers.

Enzymes thus play a vital role in supporting sustainable and cost-effective animal protein production through optimized feed formulation approaches. This remains a rapidly growing application segment for industrial enzymes.

Biofuels

Lignocellulosic biomass streams represent a abundant renewable resource for biofuel production through enzymatic breakdown of plant cell wall polysaccharides. Cellulases, hemicellulases and accessory enzymes synergistically hydrolyze cellulose and hemicellulose content into fermentable sugars.

Amylases are employed where starch containing grains serve as feedstock. For bioethanol, the liberated sugars are fermented to alcohol using microbes. For biodiesel, lipases play a key role in transesterification of plant oils/animal fats to fatty acid esters.
