Biotechnology Products

The list below would introduce you to some of enzyme biotechnology products you might use in your daily lives. The commercial processes first exploited naturally occurring enzymes. However, the enzymes being used may not be as effective as they should be. With advanced technology and time, research and development has helped improve protein engineering methods. Most enzymes are now genetically modified to be more effective under the optimal temperatures, pH or under other manufacturing conditions that are typically inhibitory to enzyme activity making them more suitable for industrial or home applications.


Some enzyme biotechnology products are: Detergents, Foods and Beverages, Leather and Biodegradable Plastic.


1. Stickies Removal

Enzymes are used by the pulp and paper for the removal of “stickies”. “Stickies” refers to the glues, adhesives and coatings that are introduced during the recycling of paper. Stickies are generally tacky, pliable organic materials that reduce the quality of the final paper product but also clog the machinery which causes the cost hour of downtime. Historically, chemical methods for removal of stickies have not been 100% satisfactory. These known stickies are held by ester bonds, the use of esterase enzymes in pump has vastly improved their removal. Esterases help to cut the stickies into smaller, facilitating their removal from the pulp. It has generally become a common approach for stickies control. The disadvantages are they are typically only effective at moderate temperature and pH. Certain esterases are only effective against some types of esters and the presence of other chemicals in the pulp can inhibit their activity. Scientists are now on the search for newer enzymes and genetically modifying existing enzymes to broaden their effective temperature and pH ranges.


2. Detergents

There are many kinds of enzymes used in detergents. Ever since their first introduction by Novozymes, the traditional use of enzymes in detergents involving those that degrades protein causing stains. Lipases are another useful enzyme that can be used to dissolve fat stains and clean grease traps or other cleaning applications. The current area of research is the investigation of enzymes that can tolerate even higher activities in both hot and cold temperatures. These enzymes are desirable for improving the laundry processes in hot water or at cold water for washing. Additionally, they are useful for industrial processes in high temperature.


3. Textiles

Enzymes are widely used to prepare fabrics that your clothing, furniture and other household items are made. Demands are increasing to reduce pollutions caused by the industry. This has fueled biotechnological advances that have replaced chemicals with enzymes in all manufacturing processes. They are now used to enhance the preparation of cotton for weaving, reducing the impurities, minimizing the pull in fabrics. All of these not only make the process less toxic and eco-friendly, they also help reduce the costs associated. At the end of it, it helps improve the quality of final textile products.


4. Leather

The process of tanning hides into useable leather involves the use of many harmful chemicals. Enzyme technology has advanced so much that some of these chemicals are already replaced and the process is now faster and more efficient. There are enzymes applied to the first step of the process where fats and hairs are being removed from hides. Enzymes are also used during cleaning, and keratin and pigment removal. It also aids the stabilization of leather to prevent it from rotting.


5. Biodegradable Plastic

Plastics that are typically manufactured by traditional methods usually come from non-renewable hydrocarbon resources. They consist of long polymer molecules that are bounded tightly together and are not often broken down easily. Biodegradable plastics are made using plant polymers usually from wheat, corn or potatoes. They consist of shorter, more easily degraded polymers. Biodegradable plastics are also more soluble. Genes for enzymes involved have been cloned to plants which can produce the granules in them. Plant based plastics have been limited due to their cost and thus not widely accepted by consumers.
