Short summary

We investigated how cloud water pH and solar radiation impact the survival and energetic metabolism of two neutrophilic bacteria species and their biodegradation of organic acids. Experiments were performed using artificial cloud water that mimicked the pH and composition of cloud water in South China. We found that there is a minimum cloud water pH threshold at which neutrophilic bacteria will survive and biodegrade organic compounds in cloud water during the daytime and/or nighttime.
