Biocatalysis involves the use of biological molecules, primarily enzymes, to drive chemical reactions. Enzymes are highly specific catalysts that accelerate reactions by lowering the activation energy needed. They operate under mild conditions, such as ambient temperature and neutral pH, which contrasts sharply with the extreme conditions often required in traditional chemical processes [1,2].

Methodology

Enzymes are highly selective for their substrates, meaning they catalyze specific reactions with high precision. This selectivity minimizes by-products and increases yield. Enzymatic reactions typically occur at lower temperatures and pressures compared to conventional chemical processes, reducing energy consumption and the need for harsh chemicals. Enzymes are not consumed in the reaction and can be used repeatedly, which enhances the efficiency and sustainability of the process.

Applications of biocatalysis

Biocatalysis is employed across various sectors, including pharmaceuticals, agriculture, food and beverages, and environmental management. Each application benefits from the unique advantages of enzymatic processes.

In the pharmaceutical industry, biocatalysis is used to synthesize complex molecules and drug intermediates with high precision. Enzymes enable the production of chiral compounds, which are essential for creating effective drugs. For instance, the enzyme chymotrypsin is used in the synthesis of specific beta-lactam antibiotics. Additionally, biocatalysis can streamline the synthesis of complex molecules, reducing the number of steps and overall costs of drug production [3-5].

Biocatalysis in agriculture primarily involves the development of enzyme-based formulations for pest control and soil health. Enzymes like chitinase are used to break down chitin, a component of insect exoskeletons, making them effective in controlling pests. Moreover, enzymes are employed to enhance soil fertility by decomposing organic matter into valuable nutrients, improving crop yields and sustainability.

The food industry leverages biocatalysis for processes such as fermentation, flavor enhancement, and food preservation. Enzymes are used to convert starches into sugars during brewing, cheese-making, and baking, optimizing flavor and texture. For example, the enzyme lactase is added to dairy products to break down lactose, making them suitable for lactose-intolerant individuals.

Biocatalysis offers promising solutions for environmental cleanup and waste management. Enzymes can degrade pollutants such as hydrocarbons, pesticides, and plastics, contributing to bioremediation efforts. For instance, the enzyme laccase is used to break down lignin in paper mills and to treat industrial effluents. Additionally, biocatalysis is used in wastewater treatment to remove contaminants and toxins, promoting cleaner water sources [6-9].
