Biology grade 12
-> Biotechnology is the application of scientific knowledge by industries that produce biological products like food supplements, enzymes, and drugs.
● Yeasts (Fungi), moulds (Fungi) and bacteria are important microorganisms used in industries.
-> Fermentation is a process by which sugar is converted into alcohol and CO₂ by yeast.
-> Fermentation by the yeast Saccharomyces yields beer and that by
Lactobacillus, yields butter milk.
-> Tissue culture, a method of biological research in which fragments of tissue from an animal or plant are transferred to an artificial environment in which they can continue to survive and function. The cultured tissue may consist of a single cell, a population of cells, or a whole or part of an organ.
-> Genetic engineering involves the transfer of genes from one organism to an unrelated species. Genetic engineering is being used in the production of pharmaceuticals, gene therapy, and the development of transgenic plants and animals.
-> Wastewater may come from domestic
or commercial sources; highly toxic
industrial effluents may require pretreatment before entering a water treatment system. Sewage is the term used to describe liquid wastes that contain faccal matter (human or animal).
