| Abstract: | Methyl iodide (CH3I) and methyl bromide (CH3Br) were produced by an axenic kelp-tissue culture and methyl iodide was produced by microbial cultures derived from decaying kelp tissue, demonstrating that methyl iodide is a product of both kelp and microbial metabolism. Methyl iodide production by blade tissue from five kelp species was not enhanced by desiccation, but production rates were enhanced by drastic cellular disruption. Wounding and tissue age of Macrocystis pyrifera had no effect on methyl iodide production. Undefined microbial populations, obtained from decaying kelp, produced methyl iodide at low rates while growing on suspensions of powdered kelp tissue in seawater and on artificial media. This study (1984–1985 on kelp collected from California, USA) confirms that direct methyl iodide production by kelp is not globally significant, but suggests that production by marine microbes associated with seaweed degradation may be of global importance.Please address all requests for reprints to Dr. S.
