What is a main drawback of using cyanobacteria as biofuel?
Though cyanobacteria do not compete with food crops in terms of land, there is some concern that competition for nutrients may become an issue. Cyanobacteria require a source of nitrogen and phosphorous just as plants do, and fertilizer production for plant growth is already a huge industry.
Why should we not use algae as biofuel?
Algae require a significant water source available to maximize growth. Temperature levels for the best growth cause water to evaporate, so algae biofuel uses much more water than other resources. This means that agricultural water resources may have to be diverted and used.
How are cyanobacteria different from other algae?
The key difference between cyanobacteria and algae is that cyanobacteria are a group of prokaryotic bacteria while algae are small eukaryotic plant-like organisms. Among these three types, cyanobacteria are prokaryotes, which are bacteria. On the other hand, green plants and algae are eukaryotic organisms.
Why Is algae the best biofuel?
Advantages for Biofuels A significant advantage of using algae for biofuels is that it need not displace farmland used for growing food sources. The Department of Energy reports that algae have the potential to yield at least 30 times more energy than land-based crops currently used to produce biofuels.
Where do cyanobacteria get their carbon?
Thus cyanobacteria have a natural potential to produce sugars from photosynthesis using CO2 as the sole carbon source.
What are the advantages and disadvantages of using marine algae as a biofuel?
List of the Advantages of Algae Biofuel
- Algae grows at higher efficiency levels than other biofuel crops.
- Algae is more productive than other forms of biomass.
- Algae is a renewable resource.
- Algae produces viable hydrocarbons for numerous products.
- Algae is something that almost anyone can grow.
How is algae used as biofuel?
How does algae produce biofuel?
- Algae are cultivated in large pools or farms.
- The micro-organisms convert sunlight to energy, and store the energy as oil.
- The oil is extracted using a mechanical process such as pressing or using sound waves, or with chemical solvents that break down the cell walls and release the oil.
What is the difference between cyanobacteria and eubacteria?
The difference between cyanobacteria and eubacteria are: The eubacteria contain any bacteria that are prokaryotes with one cell. In contrast, cyanobacteria are the type of these organisms. Some eubacteria can produce organic material for metabolic activities, while some can obtain it from outside.
How are green algae different from cyanobacteria quizlet?
Green algae are eukaryotes while cyanobacteria are prokaryotes. while cyanobacteria do not contain them. Green algae consist of chloroplasts while cyanobacteria lack chloroplasts.
Can algae biofuel replace oil?
Key to algae’s potential as a renewable fuel source is its biomass per acre; some research indicates that algae could be 10 or even 100 times more productive than traditional bioenergy crops. Experts estimate that it takes nearly 140 billion gallons of algae biodiesel to replace petroleum-based products each year.
