Industrial biological catalysis through enzymes has experienced rapid growth in recent years due to their ability to operate at mild conditions, and exceptional chiral and positional specificity, things that traditional chemical processes lack. [1] Isolated enzymes are typically used in hydrolytic and isomerization reactions.
Microbial enzymes are widely utilized as biocatalysts in fields such as biotechnology, agriculture, and pharmaceuticals. Metagenomic data serve as a valuable resource for identifying novel CUEs from previously unknown microbes present in complex microbial communities across diverse ecosystems.
Industrial fermentation is the intentional use of fermentation in manufacturing processes. In addition to the mass production of fermented foods and drinks, industrial fermentation has widespread applications in chemical industry. Commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation. [1]
Enzymatic polymerization is a potential area in polymer research, providing a sustainable and adaptable alternative to conventional polymerization processes. Its capacity to manufacture polymers with exact structures in mild circumstances opens up new possibilities for material design and application, helping to progress both research and industry.
The Haber process requires high pressures (around 200 atm) and high temperatures (at least 400 °C), which are routine conditions for industrial catalysis. This process uses natural gas as a hydrogen source and air as a nitrogen source.
Psychrophilic extremophiles have the ability to maintain high growth rates and enzyme activity at temperatures even as low as 0°C. This presents the possibility of utilizing enzymes found in these organisms in parallel to how thermophilic organism enzymes are used, but at low temperatures as opposed to high temperatures. [4]
It is an essential step in the manufacture of pharmaceuticals such as antibiotics, hormones (e.g. insulin and human growth hormone), antibodies (e.g. infliximab and abciximab) and vaccines; antibodies and enzymes used in diagnostics; industrial enzymes; and natural fragrance and flavor compounds.
Processes are conducted in vessels up to 60,000 gal in volume. Sugars, methionine, and ammonium salts are used as C,S,N sources. Genetically modified Penicillium chrysogenum is employed for penicillin production. [4] Some steroids are hydroxylated in vitro to give drugs.
