July is the most beautiful season in Qingdao, blowing cool sea breeze, enjoy the beauty of the seaside, a wave rushed in, alas?Why are waves green?It's enteromorpha, here it comes again
Impression from the 2008 Qingdao Olympic sailing competition,enteromorpha visit Qingdao every year, and this year the scale has been the most in history, should be clean beach layer by layer of Margin covered, which makes the seaside tourist city of Qingdao famous tourist experience worse a lot.Today we talk about enteromorpha ~
Part1 What is Enteromorpha ?
Enteromorpha is a kind of bright green algae of the genus Enteromorpha prolifera in the family Ulva, consisting of a single layer of cells that are enclosed in tubes or bands of adhesion.Enteromorpha green algae mainly distributed in coastal waters, especially luxuriant growth near the nutrient rich river estuaries, is a kind of euryhaline algae.China's coastal wild Enteromorpha green algae resources are very rich, mainly distributed in fujian, Zhejiang, Jiangsu coastal.
Part 2 Enteromorpha why flood in Qingdao?
Enteromorpha green tide has been breaking out in the South Yellow Sea for more than a decade, which is characterized by large scale and heavy damage, causing serious damage to the Marine ecosystem.The green tide of Enteromorpha in the Yellow Sea first appears in the form of floating green algae in the vicinity of the northern Jiangsu shoal sea area in March and April every year, and gradually gathers under the action of wind and current, and gradually drifts northward. Finally, it appears in the waters around Qingdao in a large scale in June and July, and slowly rots and dies out after August.
Usually enteromorpha needs certain conditions will outbreak, for example, the water eutrophication, seawater N P excess ammonia nitrogen composition, in particular, this will cause the enteromorpha blooms, at the same time, combined with the global warming, increased carbon dioxide in the atmosphere composition makes when water and air exchange, increased the content of carbon in water, this could stimulate enteromorpha breeding.
Part3 The harm of enteromorpha overspread
Just like red tide, a large number of enteromorpha can also cover the sun, affect the growth of algae on the sea floor: death of Enteromorpha will also consume oxygen in the sea; Studies have also shown that chemicals secreted by Enteromorpha are likely to adversely affect other Marine life. A large number of Enteromorpha floating gathered to the shore, blocking the channel, and a large amount of accumulation of Enteromorpha rot breeding need to consume a lot of oxygen, and emit a foul smell.Damage Marine ecosystem, serious threat to coastal fisheries, tourism development.So, the foreign has been enteromorpha a large green algae outbreak called "green tide", as a Marine disaster and red tide.
Part 4 Dose Enteromorpha has the value that can be use?
Enteromorpha as a kind of green algae itself contains rich protein, amino acids, unsaturated fatty acids, minerals, dietary fiber content is high, iron and zinc content is significantly higher than other algae, enteromorpha can do food such as noodles, cosmetics such as enteromorpha mask, can also be used as feed and organic fertilizer.It is worth mentioning that enteromorpha polysaccharide extracted from Enteromorpha prolifera is a hot topic in academic research in recent years.In March 2020, Trends in Food Science & Technology, an international Food journal, published a report entitled "Polysaccharides from Marine Enteromorpha:Structure and function.
It has been reported that Marine Morphmorpha prolifera polysaccharides (EPPs) have a variety of physiological and biological activities due to their special chemical structure such as monosaccharide composition and glycosylic bonding.The modified enteromorpha prolifera polysaccharide has some strong biological activity function.It was found that low molecular weight ENTERomorpha vulcanis polysaccharide had excellent immune-related activity and antioxidant activity.Carboxymethylation, hydroxyl oxime acidification, phthalylation and acetylated derivatives could significantly improve the antioxidant and antibacterial activities and hygroscopicity of Entermorpha prolifera polysaccharide.Relative to general drugs, EPPs can be used as a natural agent, with outstanding efficacy.In addition, studies have shown that Entermorpha prolifera polysaccharides have antioxidant, anti-tumor activity, antibacterial activity, regulation of intestinal microbiome, blood lipid lowering activity, anticoagulant activity, entermorpha prolifera polysaccharides also show a variety of biological activities and potential health benefits, such as respiratory burst, anti-virus and anti-cancer.
Have seen so many believe that everyone on Entermargin understanding has been very full, I believe that through our efforts, Entermargin in the near future will no longer be a disaster, Qingdao still has blue sea and sky ~
