Chapter 8 Flashcards
What is biotechnology?
large-scale industrial use of biological processes using microorganisms to produce substances that benefit humans and society. Biotech provides both products and service; like insulin which is a product and sewage treatment which is a service
name the medical products produced by large scale fermentation
the most economically beneficial uses of large scale fermentation are the production of penicillin, insulin, and human growth hormone etc.
A fermenter may hold several thousand litres of growth medium, so products can be produced in bulk, which makes the process inexpensive.
how has genetic engineering improved the quality of agricultural yield
reduced the need for pesticides AND ENHANCED NUTRIENT COMPOSITION AND Overall quality.
Can give plants insect resistance
certain genes can give resistants to pathogens and herbicides, which enable farmers to kill weeds without harming crops.
can protect animals from diseases
Animal propagation via cloning is possible with advanced techniques.
why is 40c the best temp for yogurt production
it falls within the ideal range for the bacteria cultures used to ferment milk into yogurt, allowing them to multiply rapidly and efficiently, resulting in a smooth, consistent texture and desirable tangy flavor while minimizing the risk of unwanted bacterial growth
