What category does algae fall into?

algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.

What is CO2 Biofixation?

CO2 biofixation using microorganisms involves the cultivation of autotrophic microbes, which capture CO2 from the atmosphere or other sources (e.g., flue gases) for cell growth and extracellular product synthesis, in different cultivation systems such as natural waters, open ponds, and photobioreactors.

What generation is algae biofuel?

third-generation biofuel
Fuel derived from algae, dubbed the ‘third-generation biofuel’, holds several key advantages over earlier feedstocks based on plant crops such as sugar cane and corn (the first generation of biofuel production) and vegetable or animal waste streams (the second).

What is genetically modified algae?

With genetic engineering, scientists can develop algae that grow faster and ward off deadly bacteria. They can create algae that produce more oil — which can then be turned into biofuels or biodegradable plastics. Or, they can engineer algae to be more nutritious, whether consumed by livestock or people.

What are the 3 main classifications of algae?

There is three main Algae classification:

  • Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b.
  • Phaeophyceae – Also called as brown algae, they are predominantly marine.
  • Rhodophyceae – They are the red algae because of the presence of the red pigment, r-phycoerythrin.

What are the 11 classification of algae?

There are 11 types of algae such as Chlorophyceae (Green algae), Phaeophyceae (Brown Algae), Rhodophyceae (Red Algae), Xanthophyceae (Yellow-Green Algae), Chrysophyceae (Golden Algae), Bacillariophyceae (Diatoms), Cryptophyceae, Dinophyceae, Chloromonadineae, Euglenineae, and Cyanophyceae or Myxophyceae (Blue-green …

What is the meaning of Biofixation?

Biofixation is the same thing except it refers to the use of organisms(usually plants or other photosynthetic organisms) for the sole purpose of removing carbon dioxide from the atmosphere…

Which algae used for water treatment?

Chlorella – Chlorella is used for the removal of lead (II) ions from wastewater. It is also used to remove nutrients (N and P) from domestic wastewater. It is used in the treatment of diluted piggery waste and in the detoxification of cyanide from wastewater.

What are third generation biofuels?

The most accepted definition for third-generation biofuels is fuels that would be produced from algal biomass, which has a very distinctive growth yield as compared with classical lignocellulosic biomass (Brennana and Owendea, 2010).

How many species of microalgae are there?

Approximately 40,000 different species of microalgae have been reported [59]. Microalgae culture depends on the species and is affected by factors such as nutrient availability (N, P, K, etc.), temperature, pH, salinity, inorganic carbon, oxygen, light intensity, and CO2 [60].

What is the difference between microalgae and macroalgae?

The key difference between macroalgae and microalgae is that macroalgae are large and multicellular aquatic photosynthetic plant-like organisms while microalgae are small and unicellular aquatic photosynthetic plant-like organisms.
