Environmental biotechnology can simply be described as "the optimal use of nature, in the form of plants, animals, bacteria, fungi and algae, to produce renewable energy, food and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process". [3]
Some enzymes are used commercially, for example, in the synthesis of antibiotics. Some household products use enzymes to speed up chemical reactions: enzymes in biological washing powders break down protein, starch or fat stains on clothes, and enzymes in meat tenderizer break down proteins into smaller molecules, making the meat easier to chew.
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.
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 ] Having the ability to live in such harsh environment comes from the organisms traits and abilities that are coded into their genomes.
For example, presence of a low-molecular weight soluble substrate such as glucose will inhibit enzyme production by repressing the transcription of associated cellulose-degrading enzymes. [ 17 ] Environmental conditions such as soil pH , [ 18 ] soil temperature, [ 19 ] moisture content, [ 20 ] and plant litter type and quality [ 21 ] have the ...
The catalysts, i.e. the enzymes, are amenable to improvement by genetic manipulation. [citation needed] Biotechnology usually is restrained by substrate scope. Petrochemicals for example are often not amenable to biotransformations, especially on the scale required for some applications, e.g. fuels.
-Enzymes exhibit extreme selectivity towards their substrates. Typically enzymes display three major types of selectivity: Chemoselectivity: Since the purpose of an enzyme is to act on a single type of functional group, other sensitive functionalities, which would normally react to a certain extent under chemical catalysis, survive. As a result ...
Their teeth grind the food up, enzymes and acid in the stomach liquefy it, and additional enzymes in the small intestine break the food down into parts their cells can use. Extracellular digestion is a form of digestion found in all saprobiontic annelids , crustaceans , arthropods , lichens and chordates , including vertebrates .
