Microalgae Cultivation and Extraction Methods

The video explores the potential of microalgae in revolutionizing the food and cosmetic industries. It discusses the growth conditions necessary for microalgae, the extraction process of omega-3 and antioxidants, and compares microalgae to fish as a source of omega-3. The video also highlights the market potential and future prospects of microalgae products, emphasizing sustainability and efficiency.

What is the primary focus of the research institute mentioned in the video?

• Studying water pollution

• Creating artificial ponds

• Growing microalgae for food and cosmetics

• Developing new fish species

Which of the following is NOT a requirement for growing microalgae?

• Agitation

• Constant light source

• Stable temperature

• Chemical fertilizers

How do scientists ensure that light reaches the entire microalgae organism?

• By rotating the greenhouse

• By using mirrors

• By keeping the microalgae in constant movement

• By using transparent containers

What method is used to extract omega-3 and antioxidants from microalgae?

• Boiling the microalgae

• Using chemical solvents

• Injecting carbon dioxide at high pressure

• Freezing the microalgae

What is the role of carbon dioxide in the extraction process?

• It acts as a solvent

• It breaks down the algae

• It is used to increase pressure

• It cools the microalgae

Why is microalgae considered a more sustainable source of omega-3 compared to fish?

• Fish are overexploited and microalgae is more efficient

• Microalgae does not require water

• Fish naturally produce more omega-3

• Microalgae grows faster than fish

What is the main challenge in making microalgae-based products more competitive?

• Lack of consumer interest

• Limited availability of microalgae

• High production costs

• Ineffective marketing strategies

What is the expected impact of scaling up microalgae technology on product prices?

• Prices will fluctuate unpredictably

• Prices will decrease

• Prices will remain the same

• Prices will increase

What is the estimated global demand for omega-3 per year?

• 1,000,000 tons

• 100,000 tons

• 260,000 tons

• 500,000 tons

What legislative change do researchers hope for in the future?

• Bans on microalgae cultivation

• Legislation favoring sustainable extraction methods

• Stricter regulations on fish farming

• Easier extraction using chemical solvents
