This type of respiration needs oxygen for it to occur so it is called aerobic respiration. Glucose + Oxygen -> Carbon dioxide + Water + Energy The chemical equation is: C 6 H 12 O 6 + 6O 2 -> 6CO 2 + 6H 2 O + 2900 kj 3 stages: -glycolysis -citric acid cycle -electron transport chainRead More

FAQs on PPT - Fermentation Technology - Chemical Technology - Chemical Engineering
| 1. What is fermentation technology in chemical engineering? |  |
Ans. Fermentation technology in chemical engineering refers to the process of using microorganisms, such as bacteria or yeast, to convert organic substances into useful products through anaerobic or aerobic metabolic pathways. It involves the controlled growth of microorganisms in a bioreactor, where they consume nutrients and produce desired products, such as ethanol, enzymes, or antibiotics.
| 2. How is fermentation technology used in the production of biofuels? | |
Ans. Fermentation technology plays a crucial role in the production of biofuels. It involves the fermentation of biomass, such as crops or agricultural waste, by microorganisms to produce biofuels like ethanol or biodiesel. During the fermentation process, enzymes break down the complex carbohydrates present in biomass into simpler sugars, which are then consumed by microorganisms to produce biofuels through their metabolic pathways.
| 3. What are the advantages of using fermentation technology in chemical engineering? | |
Ans. There are several advantages of using fermentation technology in chemical engineering:
- It allows for the production of a wide range of valuable products, including biofuels, pharmaceuticals, enzymes, and organic acids.
- Fermentation processes are often highly efficient, with high product yields and minimal waste generation.
- It is a sustainable and environmentally friendly method, as it relies on renewable resources and reduces the dependence on fossil fuels.
- Fermentation technology can be easily scaled up for large-scale production, making it economically viable for industrial applications.
- The use of microorganisms in fermentation processes can also lead to improved product quality and purity.
| 4. What are the challenges in fermentation technology? | |
Ans. There are several challenges in fermentation technology:
- Contamination: The growth of unwanted microorganisms can lead to contamination and reduce the yield and purity of the desired product.
- Optimization: Finding the optimal conditions for microbial growth and product formation can be complex and time-consuming, requiring extensive research and experimentation.
- Scale-up: Scaling up fermentation processes from laboratory-scale to industrial-scale can be challenging due to the need for larger bioreactors, efficient mixing, and oxygen transfer.
- Downstream processing: Extracting and purifying the desired product from the fermentation broth can be a complex and costly process, requiring advanced separation techniques.
- Cost: The cost of fermentation technology, including the raw materials, equipment, and energy requirements, can be a significant factor that needs to be considered for commercial viability.
| 5. What are some applications of fermentation technology in chemical engineering? | |
Ans. Fermentation technology finds various applications in chemical engineering, including:
- Production of biofuels, such as ethanol and biodiesel, as renewable alternatives to fossil fuels.
- Manufacturing of pharmaceuticals, including antibiotics, vaccines, and therapeutic proteins, through microbial fermentation.
- Enzyme production for various industrial processes, such as food processing, textile manufacturing, and detergent production.
- Production of organic acids, such as citric acid or lactic acid, used in the food and beverage industry.
- Bioconversion of agricultural waste into value-added products, such as biofertilizers or animal feed supplements.
