Study Notes
Introductory Microbiology - Week 12: Biotechnology
- Biotechnology is technology based on biology, harnessing cellular and biomolecular processes to develop technologies and products for industrial use.
- Research may develop a product but requires scaling up for commercial application.
- Biology/biological entities include plants, animals, fungi, bacteria, and archaea, which can also be defined as microorganisms.
- Biotechnology can directly harness microorganisms or indirectly use them with recombinant DNA technologies.
- An example of traditional biotechnology utilization in food production is fermentation, which uses microbes. This includes fermented milks, fermented meat/fish, and cheese production.
- Microbes in wastewater treatment are used for composting and processing waste management for reduced organic content.
- Microbes are involved in producing bioactive compounds such as antibiotics, amino acids, organic acids, vitamins, biosurfactants, and biopolymers. Industrial manufacturing of these compounds uses controlled conditions and specific culture media.
- Traditional biotechnology is based on utilizing the existing metabolic capabilities of microorganisms to convert organic waste/food sources into other useful compounds.
- Techniques like genetic modifications (e.g., mutation) and pathway engineering, using genes from different organisms, create new capabilities to increase efficiency and improve yields.
- Pathway engineering involves transferring and expressing genes between organisms to create novel metabolic processes, e.g., changing biochemical pathways in microorganisms to synthesize or degrade important compounds (e.g., pollutants).
- Growing microbes in stirred fermenters or continuous feed systems can also optimize production using a rich diet of substrates. This prevents undesirable by-products from accumulating.
- Growing microbes at an industrial scale is more energy efficient, cheaper, yields more product, and produces less toxic waste compared to chemical synthesis.
- Traditional biotechnology utilizes natural metabolic capabilities. Genetic manipulation through molecular techniques can enhance and expand these capabilities. This allows the use of microorganisms in production of compounds not naturally produced by the original microorganism. This also happens by introducing heterologous genes into microorganisms.
- Genetically modifying or engineering organisms modifies genes to better yield product such as a higher yield of penicillin, more efficient catalysis of biochemical pathways, or enhanced gene expression in cheaper conditions.
- This is done using techniques like random mutagenesis (e.g., UV, transposons, chemicals) followed by screening for desired mutation outcomes and site-directed mutagenesis (using preselected mutation sites in genes).
- Environmental gene mining is a method used when specific genes needed for an engineered pathway are unknown. This involves collecting DNA from diverse environments to identify functional genes for useful applications.
- Transgenic microorganisms (e.g., cloning the bovine somatotropin gene into bacteria or using plants and animals) enables production of useful compounds like human hormones, blood coagulants, immune modulators, or replacement enzymes.
- Microbial fuel cells use microorganisms to oxidize organic matter anaerobically and produce electricity by harnessing electron transfer across the cell membrane as ions move.
- Microbial biosensors use living microbial cells, enzymes, or organelles as receptors for detection of specific substances, which triggers biological reaction products and generates electric currents.
- Synthetic biology stitches together bits of DNA to create new genetic entities, allowing the alteration of existing organisms or the development of entirely new ones. This creates new organisms with modified properties, including the production of targeted industrial products for diverse uses. (See page 24)
