Microalgae are currently harvested
in giant ponds which employ a
variety of harvesting methods.
Pelletization of microalgae has the
potential to be more economical
than any other harvesting methods.

Microalgae Pellets Allow for Easier Algae Harvest
HARVESTING MICROALGAE FOR BIOFUEL AND NUTRITIONAL SUPPLEMENTS
Microalgae have significant potential as a source of nutritional supplementsand biofuels. Unfortunately, harvesting algae is a costly and energy-intensiveprocess which consumes 20-30% of the overall production costs. Currentcommercial methods for algae harvest, such as sedimentation, filtration, orflocculation, are expensive or do not work for algae with small cell sizes.
GROWING MICROALGAE WITH FILAMENTOUS FUNGI
A process for microalgae harvest has been developed, which involvesco-culture of microalgae with certain species of filamentous fungi, enablesthe filamentous feature to the microalgae culture and induces cellaggregation to form microalgae cell pellets. This allows for a simple methodfor removal of microalgae cells from closed bioreactors and open ponds,eliminates the needs for chemicals or flocculation agents, and may be lessexpensive than existing methods. Also, it alleviates the mutual shadingeffects during the algae cell cultivation and will increase the final microalgaecell concentration.
FEATURES AND BENEFITS OF MICROALGAE PELLETIZATION:
Method is simple and inexpensive to implement and allows for easierharvesting of algae
Co-culture with filamentous fungi can be utilized in both closed reactorsand open ponds
Eliminates need for expensive equipment, such as centrifugesMore environmentally friendly - process does not use chemicals
