Study Notes
Biotechnology and bioinformatics involve the use of microorganisms and genetic information to produce useful products and solve biological problems. Microorganisms are used in industry due to their metabolic diversity and fast growth rate, while bioinformatics helps in identifying target genes for genetic engineering.
- Microorganisms — small organisms used in industry for their fast growth and diverse metabolic capabilities. Example: Bacteria used in fermentation to produce antibiotics.
- Fermenters — vessels that maintain optimal conditions for microorganism growth to produce metabolites. Example: Large-scale production of alcohol using yeast.
- Pathway engineering — manipulation of genetic processes to enhance metabolite production. Example: Increasing penicillin yield by modifying bacterial pathways.
- Transgenic organisms — genetically modified organisms that express new proteins from introduced genes. Example: Bt corn engineered to produce insecticidal proteins.
- Bioinformatics — the use of computational tools to analyze biological data. Example: BLAST searches to find similar gene sequences across species.
