Study Notes
Fermentation and Food Processing
- The primary product of the fermentation process in beer making is ethanol (alcohol).
- Lactic acid bacteria are commonly added to milk to produce yogurt, leading to fermentation and thickening of the milk.
- The tangy flavor in fermented meats like salami is contributed by the production of lactic acid and various flavor compounds during fermentation.
Vitamins and Microbial Enhancement
- Microbes can enhance the production of certain vitamins, notably increasing vitamin availability by 100 to 300 times.
- Vitamin C (ascorbic acid) is primarily produced in biotechnology using genetically modified strains of certain microorganisms.
Winemaking and Preservation
- In winemaking, sulfur dioxide is treated with juice primarily to act as a preservative, preventing oxidation and microbial spoilage.
Genetically Modified Organisms (GMOs)
- Genetically modified organisms (GMOs) are best described as organisms whose genetic material has been altered using genetic engineering techniques to exhibit desired traits.
Single-Cell Protein (SCP)
- Single-cell protein (SCP) is significant in food processing and production as a sustainable protein source, derived from microorganisms used in fermentation processes.
Role of Transgenes
- In biotechnology, transgenes play a crucial role as they are genes that have been introduced into an organism to confer specific traits, such as resistance to pests or improved nutritional content.
Vitamin B12 Production
- Vitamin B12 (cyanocobalamin) is commonly obtained for biotechnology applications through fermentation processes involving specific bacteria, particularly Propionibacterium species.
