Glossary
Semi-continuous culture (drop and top)
This is where the algae culture is regularly harvested and refilled with nutrients and water (media) diluting the algae. In our PBRs media harvests and media addition can be set up automatically. Between harvests, the algae is given time to increase in density so the density at time of harvest can be consistent.
Glossary
Salinity
The total quantity of dissolved salts in seawater, measured by weight in parts per thousand.
Glossary
RAS (Recirculating aquaculture systems)
A method of production for fish, shrimp, or shellfish where water exchange is limited. RAS takes up much less space and can be located inland and closer to the consumer.
Glossary
Raceway pond
A shallow artificial pond used in the cultivation of algae. Our bioreactors are great for inoculating large scale algae raceways.
Glossary
Photoperiod
The time that the algae is exposed to light in a 24-hour period. You can set your custom photoperiod with the PBR’s control system.
Glossary
Plankton
Any organisms that live in the water column, including zooplankton (microscopic animals) and phytoplankton (plants), that cannot move against a current.
Glossary
Phytoplankton
Microscopic, photosynthetic plants that are suspended in the water column.
Glossary
Photoinhibition
Damage caused by overstimulating algae with light, reducing photosynthetic ability. Can also occur in plants and cyanobacteria.
Glossary
Peristaltic pump
Commonly known as roller pumps. The fluid is pumped within a flexible tube fitted inside a circular pump casing. Peristaltic pumps are used for adding nutrients to the PBR and harvesting algae semi-continuously.
Glossary
Nutrient
Substances used to achieve growth. For such as nitrogen and phosphorus, used by algae to grow.
