Seasonal variation of components of Ulva pertusa by environmental parameters

Abstract

In recent years Ulva pertusa is the dominant group of the species forming “bloom” and have become even more frequent in the coastal waters of Jeju. Korea. U.pertusa are known to contain high amounts of protein, carbohydrate, abundant vitamins, dietary fibers and minerals. This study, we confirmed components of U.pertusa by seasonal variations during 2010 and 2011 for industrial production of commercial importance. The environmental parameters have shown clear seasonal variations from Jun to October. The nitrogen, carbon, amino acid, protein and lipid contents showed higher values in spring and lower values in summer. These values showed negative correlation with temperature and positive correlation with salinity. The patterns were decreased sharply towards summer and the increased during in autumn-winter months. On the other hand, the maximum ash contents occurred during summer and decreased during autumn-winter. Especially, Ca, Fe, Cu and Zn element contents observed high values in summer season. These components significantly related to environmental effect with temperature, rainfall and salinity.amins, dietary fibers and minerals.
