With the development of the chemical industry, more and more high-salinity sewage that contains the pollutant phenol. The research in this paper tested Microbial Fuel Cell (MFC) phenol degradation with a focus on the Staphylococcus caprae strain SHBCC D10058 ATCC 35538 as the degrading bacteria. In conditions with a 5% salinity medium and 100mg/L initial phenol concentration, after three days of degradation, 46.25% phenol remained. The phenol concentration was initially 220mg/L; after three days of degradation in a 5% salinity condition, 64.74% phenol remained. 65.93% of phenol remained in the medium with an initial phenol concentration of 300mg/L after three days' degradation. When the Microbial Fuel Cell was utilized with only polycarbonate brine (1.6%salinity, 4.07mg/L phenol), the cell had a maximum power output of 30.070mW/m2, and after three days of degradation, 32.31% phenol remained.

This study was designed to determine the effects of five different salinity levels (25, 30, 35, 40 and 45 ppt) on the survival rate of Farfantepenaeus aztecus larvae from Nauplius5 to post-larvae1 (N5-PL1). For this purpose, 50 larvae that reached the N5 stage were stocked in 2-L round bottom glass flasks in five replications and were grown up to the PL1 stage at 27.6±0.4°C. At the end of the study, as the highest survival (44.00±23.15) in protozoal stages were obtained at 35 ppt salinity levels, the lowest survival 14.00±4.89) were found at 25 ppt salinity levels (P<0.05). The highest survival rates from the M1 stage to the PL1 stage was obtained at 35 ppt (24.40±19.51), 30 ppt (23.20±18.14) and 40 ppt, respectively. The survival rates at 25 and 45 ppt salinity levels were found statistically different from those of 30, 35, and 40 ppt (P<0.05). The results of this study show for the first time that the optimum salinity level is the range of 30-40 ppt for larval culture obtained from the North-eastern Mediterranean population of brown shrimp that is the West Atlantic natural origin.

In the past few years, a water quality testing system has been commonly used in almost every country which is known to have issues related to water contamination. The old system uses the physical inspection of water by taking numerous samples from different water sources. These samples are then verified in the research laboratory using diagnostic technologies. Such techniques are time taking and are not deemed as powerful. Furthermore, new techniques not only inspect the physical qualities of water but also measure the total amount of germs and other infectious items present in the water. Old methods of water testing have drawbacks like complex processing, long result time & low accuracy etc. So, to eradicate all these issues, we must find out an economical and fast way to determine the quality of water. Such a device is called a "Water Salinity Tester (WST)". WST is a device that is used to calculate the amount of Total Dissolved Solids (TDS) in water. The reason for developing this sort of tool is to provide equipment that can help the users to measure the salinity of water so that it can be controlled if the salinity increases to a certain limit. The tool can be used both domestically and industrially. [ABSTRACT FROM AUTHOR]
