What is cultivation of microalgae?

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.

Which media is used for algal culture?

Fertilizer for algae: Salt broth and agar plate are the two major types of growth media used for cell culture. Typically, cultures are grown in a liquid salt broth with corresponding nutrients and maintained under optimal conditions.

Which of the following medium is used for the cultivation of microalgae?

In our lab, we use BG-11 medium to cultivate both freshwater cyanobacteria (your case) and microalgae, and we are seeing good results.

How do you harvest microalgae?

The common methods for microalgal biomass harvesting include centrifugation, filtration, flotation and flocculation. Of those techniques, flocculation is considered as an effective, convenient and preferable process for the harvesting of microalgal biomass [15].

What is the use of microalgae?

Microalgae have to date found a number of industrial applications—examples of success include formulation of food [4], feed [5], cosmetics [6], health products [7], and fertilizers [8], as well as tools for wastewater treatment [8,9] and biofuel production [5].

How long does it take to culture algae?

It will take about three to four weeks to grow up enough algae in the bottles to monitor change using a light meter smartphone app.

What are the best conditions for algae to grow?

Algae only require a few essentials to grow: water, sunlight, carbon, and nutrients like nitrogen and phosphorus. From salt water to fresh water and everything in between, the diversity of algae means that there are suitable strains that can take advantage of nearly any water resource.

How do you isolate microalgae?

2. Microalgal Isolation and Purification Techniques

  1. 2.1. Sampling. The collection of microalgal samples is a crucial step for isolation of microalgae from their natural environment.
  2. 2.2. Isolation of Single Cells.
  3. 2.3. Serial Dilution.
  4. 2.4. Streak Plate.
  5. 2.5. Density Centrifugation.
  6. 2.6. Enrichment Media.

How long does it take for microalgae to grow?

Algae growth should reach its peak by 30 days/4 weeks, though you don’t need to wait that long to harvest the algae.

What is the most direct measurement of algae culture?

Microscopic cell count is probably the most accurate method, although time consuming. Another less time consuming possibility that no one has indicated is using a Coulter Counter, probably nobody has indicated it because it would measure both microalgae and your particles, if you just looked at the total count number.

How do you dry microalgae?

However, freeze-dryer, drum dryer, natural sun dryer, and other processes to dry the biomass can be also used [6, 7, 8]. It is well known that, depending on the drying process method and conditions, there is a potential to lose quality of the microalgal biomass.
