Abstract
X-ray microanalysis of thin sections of the red alga Odonthalia dentata (L.) Lyngby shows bromine to be located to the chloroplasts, the middle lamellae and the outer cell walls. Bacteria attached to the outer cell wall also contained bromine. Three energy peaks were observed for bromine during the analysis L α a t 1.48 k e V , K α a t 11.92 k e V a n d K β a t 13.28 k e V The bromine peaks in the X-ray microanalysis probably originate from bromophenols as no other bromine-containing compounds have been identified in sufficient concentrations in this alga. The bromophenols probably migrate in the middle lamella from the chloroplasts to the cuticle.
