This research focuses on studying whether or not it is possible to enhance carrier-bacteria compatibility and carbon dioxide reduction by using ceramic carriers under anaerobic conditions in the presence of light in order to culture the photosynthetic bacteria. It was confirmed that the highest carbon dioxide reduction of approximately 53% was shown by a sample using the highest volume of the ceramic carrier. It was confirmed that such a carbon dioxide reduction is approximately 20% more efficient compared to the sample using the medium only without the ceramic carrier, and approximately 42% more efficient compared to the sample using the ceramic carrier only without the bacteria. Accordingly, it was confirmed that the ceramic carrier and photosynthetic bacteria are compatible, and that the influence of the volume of the ceramic carrier on the carbon dioxide reduction and the continuous supply of the medium during the actual field application serve as limiting factors.
