Degenerative diseases related to inappropriate FAs consumption cause the two thirds cases of the population death who are living in affluent, industrialized nations. Marine algae represent a considerable part of the littoral biomass. Many algal species have long been used as human food, animal fodder and source of valuable substances. In addition, algal species are of interest from the pharmaceutical point of view. Marine algae are rich in essential fatty acids (FAs) especially polyunsaturated fatty acids (PUFAs) such as Omega-3(n-3 seri) and Omega-6 (n-6 seri),which are important in the nutrition of humans and animals. Because of high n-3 content, the n-6/n-3 ratio in macroalgae is lower than 10 which is congruent with WHO nutritional recommendations. Although each member of marine macrophytic algae has its characteristic FA pattern, but up to now, only a limited numbers of algal species have been investigated for their FAs composition. Hence, the objective of this review study is to explain briefly the FAs content and composition in some investigated marine macroalgae and also to assess the potential of some members of three phylum macroalgae, green (Chlorophyta), Brown (Phaeophyta) and red (Rhodophyta), as the sources of FAs especially PUFAs and very long chain PUFAs (VLCPUFAs) and their beneficial effects to cure and remedy some of the human diseases.","PeriodicalId":228118,"journal":{"name":"Journal of Phycological Research","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management and protection of these variable ecosystems depend on understanding the influence of salinity on biological productivity and community structure. The object of the present study is to investigate the relationships between two basic components in Urmia Lake i.e. microalgae and physico-chemical parameters, particularly salinity level in order to provide a better understanding dynamics of this unique ecosystem. 3 sampling sites were selected in north and south of Urmia Lake. Samplings (2 samples in each site) were carried out monthly from April 2018 to October 2019. Water level, salinity, Electrical Conductivity (EC), Total Disolved Solids (TDS), pH, transparency, Phosphate and Nitrate (PO4 -3 and NO3 -) were analyzed. phytoplankton species composition and density were also determined. Statiscal analysis were performed by PAleontological STatistics (PAST) version 3.04. Totally, seven algal species were identified in Urmia Lake in this study. Bacillariophyta with 5 species was the most abundant algal group in the lake. Chlorophyta and Cyanobacteria both had 1 species, however, Dunaliella salina as the only representative of green alga alone composed about 99.5 percent of total algal density of Urmia Lake. This study indicated that salinity, TDS and EC have the highest effects on phytoplankton population structure and Dunaliella spp. dominance in Urmia Lake. However, other factors such as PO4 -3 and NO3 might have been masked by three main factors.","PeriodicalId":228118,"journal":{"name":"Journal of Phycological Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115426945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, study of springs’ algal flora biodiversity leads us to know more about conservation process. In this research, the diatom biodiversity of Tizab Spring and the spring-fed river was studied in summer and autumn 2017 for the first time. Thirty-three species were identified from which two species (Achnanthidium pyrenicum (Hustedt) H. Kobayasi and Caloneis aerophila W. Bock) are new records for diatom flora of Iran. The data revealed the flora is much similar to Karaj River flora. This similarity can be due to close geographical locations, as both rivers are located in the Central Alborz region. The distribution pattern of species was studied in Iran based on present references on Iranian aquatic ecosystems. This study presented that two-third of diatom species had a widespread distribution. Iranian flora data in comparison with European and American database showed that most species are the elements of the northern hemisphere. Diatom biodiversity studies in Central Alborz region is in its first steps. Therefore, much research is needed to reveal the diatom biodiversity and the potentiality of new species in this region.","PeriodicalId":228118,"journal":{"name":"Journal of Phycological Research","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129048671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of Phormidium sp. ISC108 was evaluate on seed germination, seedling growth criteria and photosynthetic efficiency of maize. Phormidium sp. ISC108 was applied to soil via irrigation whereas control group was irrigated via sterilized water. A significant promotion in seed germination was observed in Phormidium sp. ISC108 treated maize seeds. Similarly, seedling growth indices of treated plants including biomass production, plant heights and leaf area significantly enhanced. Chlorophyll content as well as chlorophyll a fluorescence kinetics was also positively influenced by Phormidium sp. ISC108 application. Quantum yield of photosynthesis, primary photochemical reactions, rate of exiton transfer to electron transport chain, yield of electron transport and performance index of photosynthetic apparatus significantly increased in response to Phormidium sp. ISC108 application in soil. However, values of thermal dissipation of absorbed light showed a significant reduction as a result of Phormidium sp. ISC108 treatment. Considering remarkable growth promoting properties, Phormidium sp.
