Bioreactors from Coastal BioMarine Coastal BioMarine introduces a new, high performance photoautotrophic photobioreactor for algae culture in laboratory and pilot plant applications.  This prototype model is a film fabricated, flat panel device.  Algae cell densities greater than 5 grams per liter are achievable with flat panel photobioreactors as reported in the literature.(1) The design is mass producible which implies low-cost for future commercial applications. Coastal BioMarine has designed and operated film-fabricated bioreactors for more than a decade.  Film fabricated bioreactors for mixotrophic and heterotrophic are also available.
Photoautotropic Designs This flat panel design functions with artificial light or in a green house.  It is top supported, 18 inches (45.7 cm) wide by 83 inches (210.8 cm) high.  The charge volume is 8 liters.  The culture is pneumatically mixed and functions in turbulent flow or in laminar flow.  The design is proprietary; the license to operate the prototype model is included in the purchase price. The photobioreactor operating in the Coastal BioMarine laboratory is illuminated by a computer-controlled light panel. Designs for demonstration scale and commercial scale such as biofuels or fish meal are special order and can be provided for specific applications including sterile operation.  Please contact us if this is your request.
Mixotropic and Heterotrophic Designs These are tank bioreactors circulated with an air-lift mixer.  Air or oxygen is provided by a separate diffuser.  Small units of 40 liters or less are top supported.  Larger units float in water.  The device has a settlement thwarting feature. Coastal BioMarine operated 100-liter versions of the design for a number of years, but none are operating in the laboratory now.  Experience in sterile mode was good.  There was but one contamination in three years.
