What is microalgae used for?

Microalgae can be a rich source of carbon compounds, which can be utilized in biofuels, health supplements, pharmaceuticals, and cosmetics [2]. They also have applications in wastewater treatment and atmospheric CO₂ mitigation.

What 3 things does microalgae need to grow?

2.3.3 Nutrient removal

Besides CO2 and light, algae require nutrients to grow, nitrogen (N) and phosphorus (P) being the most important ones. These can be supplied in the form of agricultural fertilizer, which is simple, easily available but can be a significant cost factor (Braun and Reith, 1993; Chisti, 2008b).

Why microalgae are potentially the most important organisms in the world?

Microalgae produce a wide range of other commercially important and valuable products. They produce vitamins, which elevates their importance as a nutritional food for people and animals [136, 142]. They also produce different types of medicinally important polysaccharides.

How are microalgae used in biotechnology?

Microalgae can provide several different types of renewable biofuels. These include methane produced by anaerobic digestion of the algal biomass, biodiesel derived from trans-esterification of microalgal lipids, bioethanol produced from carbohydrate fermentations, and photobiologically produced biohydrogen.

What are the examples of microalgae?

Typical species include Chlamydomonas reinhardtii, Dunaliella salina, and various Chlorella species, as well as Botryococcus braunii. Other important algal groups include Phaeodactylum tricornutum, Thalassiosira pseudonana, Nannochloropsis, and Isochrysis spp.

What is microalgae cultivation?

Microalgae cultivation is a water-intensive process requiring in raceways 1000L of water per kilogram of biomass (Guieysse et al., 2013) and up to 3360L of water per liter biodiesel (Farooq et al., 2015). From: Microalgae-Based Biofuels and Bioproducts, 2017.

What do microalgae produce?

Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use simultaneously the greenhouse gas carbon dioxide to grow photoautotrophically.

Is seaweed a microalgae?

Algae can be broadly divided into two groups according to size: large or 'macro' algae (commonly referred to as seaweed) and microalgae, which can only be seen under a microscope.

Is microalgae a plant?

Microalgae description. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aquatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in most situations on land.

How is oil extracted from microalgae?

The Algal oil was separated from Algae biomass by filtration and weighted it by using electronic weight balance. The extracted oil was evaporated in a water bath to release hexane. All extraction was performed in triplicates for the different parameters solvent extraction process.

Where does microalgae grow?

Microalgae are unicellular photosynthetic micro-organisms, living in saline or freshwater environments, that convert sunlight, water and carbon dioxide to algal biomass.

Is microalgae and algae the same?

Algae and microalgae are photosynthetic organisms that serve as an excellent food source in aquatic ecosystems. ... The main difference between algae and microalgae is that algae are simple, autotrophic organisms, consisting of a huge diversity among them whereas microalgae are the microscopic type of algae.

Is nostoc a microalgae?

Microalgae include not only eukaryotic algae but also cyanobacteria. ... Nostoc commune is a widely distributed, atmospheric N₂-fixing cyanobacteria. It has traditionally been used in China as food and medicine [30,31].

What are examples of cyanobacteria?

Cyanobacteria are those bacteria that obtain their energy through photosynthesis just like plants. Some examples are Nostoc, Oscillatoria, Gloeocapsa.

Is microalgae prokaryotic or eukaryotic?

Microalgae are simple microscopic eukaryotic or prokaryotic photosynthetic organisms, ranging from unicellular to multi-cellular in form [25].
