Lots of Atriplex species offer a high benefit as non-traditional forages as well. The purpose of this study is to evaluate the habitat range of four Atriplex species in the coastal area of the Mediterranean Sea of Egypt. Two of these species have C 3 photosynthesis; they are namely: A. portulacoides and A. prostrata and the other two are C 4 photosynthesis ( A. halimus and A. nummularia) . The four species are growing in the different habitats along the Mediterranean Coast from New Damietta to Burullus Lake. Associated species with Atriplex were determined and soil samples were collected to identify the types of habitats. Soil samples were analyzed to compare between C 3 and C 4 species on the basis of habitat. Results of soil analysis indicated that EC of the soil in which C 4 species grow is more than that of C 3 species and the percentages (%) of Cl - , CO 3 - and organic carbon of the soil in which C 4 species grow are more than that of C 3 species, moreover, the moisture content of the soil in which C 3 species grow is higher than that of the soil in which C 4 species grow. The obtained results from the soil variables will be useful for the understanding of the optimal habitat for C 3 and C 4 Atriplex species in the Mediterranean Coast of Egypt . Furthermore, the obtained data will help for the agro-application of these important halophytes .","PeriodicalId":507464,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141815941","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 alga was exposed to salt concentrations of 0, 140, 270 and 340 mM NaCl in the BG11 basic growth medium with pH of 7.5 ± 0.20 for 43 d. Growth, in terms of the cell number, of Chlorella sorokiniana was progressively decreased with increasing salinity levels. Nevertheless, the salinity-induced reduction in the content of photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids) was most evident at 270 mM NaCl. Salinity led to progressive increase in the concentrations of protein, soluble sugars, starch and minerals (Na + and K + ) and lipids above the control. The present findings suggest that C. sorokiniana can withstand salinity stress up to 340 mM via enhancing production of lipids and compatible organic solutes such as proline with minor contribution of protein, soluble sugars and mineral ions (Na + and K + ) .","PeriodicalId":507464,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818247","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 water physicochemical parameters as well as the qualitative and quantitative investigations of microalgae were performed seasonally from Autumn 2021 to Summer 2022. Salinity values varied between 0.4 gL-1 at River Nile Dam (S6) to 400 gL-1 at Al-Diba pond (S10). The highest concentrations of ammonia and nitrite (3.7 mgL-1 and 0.5 mgL-1, respectively) were recorded at S1 while the highest concentration of nitrate (5.37 mgL-1) was estimated at S9. Although the orthophosphate concentrations were low, total phosphorus values were acceptable. A total of 137 microalgal taxa, belonging to 7 algal groups, were microscopically identified. Diversity index values indicated that the water status varied between mildly polluted at River Nile (S6) and heavily polluted water at stations 3, 5, 8, 9, and 10. The findings concluded that the species diversity decreases by increasing the pollution as well as increasing salinity. Furthermore, the results confirmed that high species diversity coincides with low dominancy and vice versa .","PeriodicalId":507464,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818657","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}

Blood and tissue samples were obtained for the physiological and histological investigations, and a comet assay was used to determine the amount of DNA damage. Administration of ACR increased MDA, creatinine, urea, ALT, and AST activities while decreasing SOD enzyme activity. M. oleifera nanoparticle treatment raised SOD enzyme activity and decreased the damaging effects of ACR on these levels. Rats with ACR injuries treated with M. oleifera nanoparticles had improved histological abnormalities in their liver and kidneys. Greater DNA damage was seen in the liver cells of the ACR group; however, M. oleifera nanoparticles may have repaired this damage in other groups. The study concluded that M. oleifera nanoparticles provide enhanced protection against ACR's effects on liver and kidney function in rats, potentially due to its diverse phytochemicals.","PeriodicalId":507464,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818356","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}

One very efficient way to get rid of impurities from water and industrial effluent is to use zeolite removal. TiO 2 is one of the special photophysical characteristics of zeolite, which is distinguished by its numerous microscopic pores, high absorption capacity, and thermochemical stability. Sol-gel was used to synthesise zeolite and TiO 2 quantum dots (TQD) with diameters ranging from 307 to 48 nanometers. In this work, zeolite microparticles were treated with TiO 2 nanoparticles. The zeolite/TiO 2 composites were assessed using SEM, diffuse reflectance spectroscopy, Brunauer-Emmett-Teller, and X-ray diffractometer investigations. The results showed that the presence of TiO 2 nanoparticles reduces the specific surface area. However, it results in the ability to absorb ultraviolet rays. Increasing the amount of TiO 2 will cause the absorption edge to move. The photocatalytic properties of the compounds were evaluated using Blue Dianix dye removal analysis. Zeolite-TQD, with a specific surface area of 292.39 m 2 /g and a band gap energy of 3.57 eV, is the most effective material. Evidence of enhanced photocatalytic performance was obtained through analysis of spent chemical oxygen. We also confirmed the photodegradation rate of real industrial effluents using COD limitations specified in the Egyptian Environmental Law. Nine recycled zeolite-TQD samples were examined using COD measurements.","PeriodicalId":507464,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141817972","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}
