What is the main problem with using bioreactors when growing algae?
As a result, however, a number of major drawbacks have been identified [17, 35, 36, 38] including: (i) only a small number of algal species can be grown in large scale successfully; (ii) wild microbial predators are a problem; (iii) there are significant evaporative losses and water conservation therefore becomes an …
How do scientists grow algae outside in a bioreactor?
With vertical growing, algae are placed in clear plastic bags, so they can be exposed to sunlight on two sides. The bags are stacked high and protected from the rain by a cover. The extra sun exposure increases the productivity rate of the algae, which in turn increases oil production.
What is algae process?
After the oil is removed from the algae there is a lot of solid material, known as biomass. The carbohydrate content of the biomass can be converted into sugars. This can be accomplished through fermentation with yeast, giving off carbon dioxide, which can be recycled back into the growing process of the algae.
How does a bioreactor work?
Bioreactors consist of a of buried trench with woodchips through which the tile water flows before entering a surface water body. Microorganisms from the soil colonize the woodchips. These microorganisms “eat” the carbon from the woodchips and “breathe” the nitrate from the water.
What are the advantages of growing algae in a lab?
Prevent water evaporation, Lower carbon dioxide losses due to out gassing, Permit higher cell concentrations. Allow you to grow algae in any climate.
How do algae grow and develop?
They grow through a process called photosynthesis. During photosynthesis, chlorophyll absorbs the light energy of all colors but green. The green light is reflected back off of the algae which result in its green color. The photosynthesis process is the means in which algae make food and oxygen for survival.
What is algae reproduction?
Algae regenerate by sexual reproduction, involving male and female gametes (sex cells), by asexual reproduction, or by both ways. Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores.
What do you need to know about algae bioreactors?
Cultivation in algae bioreactors, or “PBR’s” are tanks or closed systems in which algae are grown. Algal culture which is grown can have a single algae strain or contain a number of strains. It depends on the type of end product desired. Controlled amounts of water, nutrients and carbon dioxide are provided in the culture medium.
How is the photosynthetic reaction performed in a bioreactor?
Fundamentally, this kind of bioreactor is based on the photosynthetic reaction which is performed by the chlorophyll -containing algae itself using dissolved carbon dioxide and sunlight energy. The carbon dioxide is dispersed into the reactor fluid to make it accessible for the algae. The bioreactor has to be made out of transparent material.
What do you need to know about algae biofuel?
In order to minimize costs, algal biofuel production usually relies on photoautotrophic culture that uses sunlight as a free source of light. Phototrophic microalgae require light, carbon dioxide, water, and inorganic salts to grow. The culture temperature should be between 15 and 30°C (~60-80°F) for optimal growth.
What was the first bioreactor made out of?
In the early days, bioreactors were used which were made of glass and later changed to a kind of plastic bag. The goal of all this research has been the cultivation of algae to produce a cheap animal feed.
