Title: METHOD OF RECYCLING CULTURE MEDIA FROM ORGANIC CARBON SUPPLIED MICROALGAE CULTURES
Abstract:
Methods of recycling culture media in microalgae cultures are described herein. Aspects of the method include centrifugation, filtration, and ozonation to reduce the concentration of bacteria in the culture medium. The method can surprisingly be performed with inclusion of one or more substances that are reduced by the ozone treatment, such as microalgae culture-inhibiting compounds and/or substances that are surprisingly not impacted by ozonation.
