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
