Mangrove swamps, mudflats and related estuarine environments provide a habitat for animals and encourage plant growth. For the people of coastal areas, estuaries are one of the vital sources of food and other economic activity. The imbalance in the quality and quantity of Estuarine water in terms of its physicochemical parameters causes adverse effects on marine life. In the present study, an attempt has been made to estimate the physicochemical properties of the estuarine water of Mithbav tidal mud flats (downstream part) of coastal Maharashtra. Several methods have been used to evaluate the variations in physical and chemical properties of estuarine water in Mithbav including standard water testing,1 the titration method and Winkler's method. Salinity, turbidity, pH, total hardness, DO, TDS, EC, nitrate, fluoride, phosphate, ammonium, magnesium, calcium, carbonate, chloride, sodium, potassium and sulphate were examined for the seven cross-sectional sites of Mithbav estuarine water. Some parameters show levels of contamination that exceed the maximum limit. For instance, during the post-monsoon season, the average value of dissolved oxygen (DO) was recorded as 11.57mg/L whereas it has been recorded as 8.07mg/L during the summer season. The total dissolved solids (TDS) showed an average increase from 141.54 to 348.57ppt between pre and post-monsoon seasons. The electrical conductivity (EC) also increased from 45558.17μ S/Cm to 31445.85 μ S/Cm respectively from the dry to the wet season. The fluoride levels during the post-monsoon season ranged from 1.07 mg/L at CS-1 to 4.2 mg/L at CS-6. The study shows that the Mithbav coastal ecosystem and nearby areas are at significant risk of contamination from physiochemical parameters that could harm the environment.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486731","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}

Biosynthesized AgNPs significantly inhibited and reduced the growth of medically important survival microorganisms (Streptomyces viridodiastaticus MGR 23 against Streptomyces toxytricini D2, Acidothermus cellulolyticus CA16, Streptomyces sp.

Our data elucidated that the biosynthesized Ag-NPs had a highly cytotoxic effect against the cancerous L6 cell line under in vitro conditions, revealing a maximum IC50 value of 1.0 μg/mL and no known anticancer drug was used as a positive regulation. AgNPs have a remarkable synergistic impact that points to their considerable potential in nanomedicine for future clinical use as a combination therapy.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486734","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}

It has been used as herbal remedy for healing several ailments like diarrhea, skin rash, sore throat, rheumatism, fever and injury sterilization. This study was conducted to estimate the medicinal and nutritional values of R. reatam plant by determining some essential contents, minerals, vitamin C and preliminary phytochemical compounds in its leaves. The primary analysis showed that the pH value of water extract was 7.18 ± 0.03 while the percentages of essential contents in leaves were 50.83 ± 1.04 crude fiber, 12.33 ± 0.76 crud lipids, 6.02 ± 0.01 crude protein, 5.00 ± 0.00 total ash content, 10.00 ± 0.00 ash soluble in water, 5.00 ± 0.00 ash insoluble in acid and 19.67 ± 0.58 moisture content. Primary tests of the crude aqueous extract revealed the presence of tannins , saponines, alkaloids flavonoids, glycosides, resins, terpenoids and steroids, while the ethanolic extract showed positive results for tannins, alkaloids, flavonoids, glycosides, terpenoids and steroids, but negative results for saponines and resins. The percentages of phytochemical compounds in the air dried leaves powder were 5.67 ± 0.58 tannins, 10.42 ± 0.72 saponines, 8.33 ± 0.76 alkaloids and 9.80 ± 1.13 flavonoids. The amounts of minerals and vitamins (mg/100) that were determined in the R. raetam dried leaves powder were 333.75 ± 1.77 potassium, 501.25 ± 1.77 sodium, 235.50 ± 6.36 magnesium, 500.00 ± 0.00 calcium and 35.33 ± 0.29 vitamin C. The obtained results prove the traditional medicinal use of R. raetam in North and East Mediterranean regions. In addition, knowing the amounts of the essential components and bioactive compounds may help in the preparation of the exact dosages for the treatment of diseases or for livestock feeding.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486576","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}

Many factors are responsible for water pollution, among the various reasons, one of the major reason is the dyes released from the textile industry, as they contains numerous numbers of chemicals and heavy metals which affect the water and its habitats which are responsible for health problems in humans like cancer and other diseases in humans. In order to control this, elimination of azo dyes which is being released from the textile industries is necessary. In order to eliminate this, biological approach has been applied. In the present investigation, we isolated around 5 different bacterial strains from the textile effluents collected from industrial area of Solapur, Maharashtra. India in which the strain KL (SN) was found to decolorize the malachite green upto 40mg/1000ml with a 70.39% decolourization at a temperature of 280C and at a pH of 7 at 120 rpm for 4 days which was found to be highest than other strains.
