Metatranscriptomics was used to assess bacterial gene expression for catalase, superoxide dismutase, and alkyl hydroperoxide reductase across 23 bacterial genera. Bacterial transcription of these enzymes was highest during peak bloom, with catalase eliciting the most robust transcriptional response. Bacterial taxa exhibited unique transcription patterns that fell into four categories: first responders, delayed responders, downregulators, or non\u2010responders, with the largest and most diversified response during peak bloom.
