在接下来的研究中，我们研究了生物分子积累的季节模式，矿物灰分的含量，大量营养素同化和超氧化物歧化酶，过氧化氢酶和过氧化物酶的活性在一个棕色的海洋padina pavonica从研究地点在Haql，红海。总蛋白质、碳水化合物和脂肪含量在7月份最高。矿物质灰分、常量营养素和膳食纤维的值在这个月也很高，表明藻类处于营养阶段，这是收获的最佳时间。我们研究了酶活性和脯氨酸积累的变化与孔雀草季节性胁迫反应的相关性。显着更高的值为三个研究的抗氧化酶和脯氨酸积累增加在1月表明应激反应。鉴于海藻在食品和工业中的应用需求日益增长，本研究为孔雀藻的开发提供了有益的信息。在这方面，亚喀巴湾的原始自然保护区十分重要。有必要制定方法和技术，从这些资源中获得最大利益。(C)2019国家海洋学和渔业研究所。由Elsevier B.V.提供
In the following research we studied the seasonal pattern of biomolecule accumulation, content of mineral ashes, macronutrient assimilation and activity of superoxide dismutase, catalase and peroxidase in a brown marine alga Padina pavonica from the study site at Haql, Red Sea. The total protein, carbohydrate and lipid contents were highest in the month of July. The values for mineral ashes, macronutrients and dietary fibers were also high in this month suggesting that the algae is in vegetative phase and this is the best time for harvesting. We studied the changes in enzymatic activity and proline accumulation to correlate with the seasonal stress response in P. pavonica. Significantly higher values for three studied antioxidant enzymes and increased proline accumulation in January suggest stress response. Considering the growing demands for application of algae in food and industry, the present study put forward useful information for the development of P. pavonica as a good option. The pristine natural reserves of the Gulf of Aqaba are important in this regard. There is a need to develop methods and techniques to obtain maximal benefits from these resources.
