Seasonal Changes in Biochemical Content of Green Algae Ulva intestinalis Linnaeus, 1753 From Sinop Coastal Environments
Abstract
In this study, it was aimed to determine the ecological characteristics of the green algae Ulva intestinalis and the change in nutrient composition. The study material was collected seasonally from four different locations along the coast of Sinop. At the end of the analysis, statistically significant differences (P<0.05) were found between seasons and stations, and a significant increase was observed in winter protein values (11.63±2.30%) compared to other seasons. In U. intestinalis, 71.25%±1.13% carbohydrate was detected, followed by 20.50±0.16% ash, 7.82±1.16% protein and 0.44±0.04% fat detected. According to the correlation analysis between the physicochemical parameters of sea water and the nutritional composition of U. intestinalis, a positive correlation was observed between the pH and protein values only in summer. In addition, a negative correlation was found between pH and carbohydrate value throughout the year. It is believed that the data obtained as a result of this study will be an important data source in determining the most useful periods of U. intestinalis.
