要約(英語): In this study, we focused on acoustic emissions (AE) as a quantitative evaluation method of algae culture conditions. Since algae produce oxygen during photosynthesis, we thought it would be possible to detect foamed AE. Therefore, AE measurements were made in algae culture tanks and AE measurements were made using an electret sensor (ECS) to investigate the possibility of evaluating algae culture conditions. AE was detected more frequently when the lighting of the thermostatic chamber was turned on, suggesting that AE derived from algal photosynthesis could be detected. Furthermore, there was a positive correlation between the dry weight measured at the same time and the number of AEs detected, so it is expected that AE measurements using ECS can be used to monitor algae culture conditions.
