Description
Summary:Seasonal variation in bromophenol content and bromoperoxidase activity in the greenmarine alga, Ulva lactuca, was studied. Bromophenols were extracted from the alga bysimultaneous steam distillation-solvent extraction, followed by identification and quantificationby gas chromatography–mass spectrometry. A method for the extraction of bromoperoxidasesfrom the alga was developed, which includes homogenisation in Milli-Q water and addition ofglycerol. The results obtained show that both bromophenol content and bromoperoxidase activityexhibit extreme seasonal variation, with high values in summer and low ones in winter.
