- Examining hydrogen peroxide-containing organelles in seaweeds. Ramahi, Joseph S Hokeness, Keiko L Gonzales, John Allen, Jadi Marquez, Roman D P Rojas, Robin A A Ingram, Sergey Capponi, Sara Smith, Jennifer E von Herzen, Brian Dueber, John He, Zheng-Hui Seaweeds, particularly the red seaweed , produce and sequester bromomethanes, which are known for mitigating methane emissions in ruminants when used as a feed supplement. Bromomethane synthesis requires hydrogen peroxide (H O ). We developed a staining assay utilizing 3,3'-diaminobenzidine (DAB) for identifying H O in three groups of seaweeds (red, brown, and green), including intensely pigmented species. Our findings indicate the previously identified "gland cell" in , responsible for bromoform synthesis and retention, is a specialized large organelle rich in H O . Our study introduces an effective survey tool to identify promising seaweed species abundant in bromoform from diverse marine habitats.
