Natural Phage

Phages targeting specific bacteria have been used for control of bacterial pathogens in plants and humans. We report results of prophylactic use of a natural cocktail of phages on plants. Water was collected from upper reaches of the Alaknanda river where more than 200 isolates of phages have been reported. The river water was collected in April 2020 before the onset of monsoons and stored with sediments. The water was sprayed twice weekly on spinach, cabbage and coriander plants. We did not isolate, identify or multiply the phages. We sprayed the water in its natural condition after diluting it to 10 percent with normal spring water that is used for irrigation in the area. Control plots were sprayed with normal spring water only. We find 47 percent higher yields in spinach, 6 percent in cabbage and 40 percent in coriander. Natural phages of Ganga river could provide an inexpensive approach for the improvement of plant yields. Implications for prophylactic use of cocktail of phages for humans are discussed.

Abstract The structure of public water supply in Germany and the water resources used are briefly described. An overview over the legal requirements for drinking water is given, and the sources for contaminants are outlined. Then the multiple-barrier approach is discussed with respect to the resources groundwater and spring water, lake and reservoir water, and river water. Examples for treatment schemes are given and the principle of subsurface transport of river water as a first treatment step is described.

High Nitrogen Concentration

Nowadays, it has become very common to find in Japan that nitrate nitrogen concentrations are very high in spring water and in well water where the land use of a watershed is agricultural. We have often observed around 50 mg/L of nitrate nitrogen in the spring water where we live. Crops produced in those fields are mainly vegetables such as celery, cabbage, lettuce, carrots, and so on. Green tea is also popular in Japan. In order to produce good quality green tea, farmers apply a great amount of nitrogen fertilizer. This amount can reach up to 1,000 kg/ha in some areas, although the average application amounts to 628 kg/ha in Japan. As a result, ground water that is rich in nitrate flows into the river, which results in a high nitrogen concentration in river water and ground water. Further, this causes a low pH in river water in some tributary rivers in Japan, though this kind of case is very rare. We knew from field tests that if water contained a high nitrogen concentration and was introduced into paddy fields, high nitrogen removal would be performed. This paper presents the outline and results of a system on how to remove nitrogen using paddy fields (wetlands). Further, this paper presents the evaluated results of the removal quantity at the watershed level.

Purpose of the study:The purpose of this present study was determine the concentration of chloride ion in water sample which collected different site and season of river Ganga.Chloride ions in the environment can come from sodium chloride or from other chloride salts such as potassium chloride, calcium chloride and magnesium chloride. Methodology:Water sample was collected from different site(Bithor ghat, Siddnath ghat and Dhoni ghat) and different season(Pre monsoon, Monsoon and post monsoon) of river Ganga from Kanpur in 2016-2018 year. Mohr method (Argentometric method) was a very simple and highly selective method for the determination of chloride ion (Cl-) using silver nitrate as the titrant. Main Findings: In both the years 2016 till 2018, chloride concentration was within the limit at testing sites.  Applications of this study:To create awareness among the people to maintain the Ganga river water at its highest quality and purity levels. Originality: This project was done in the D G P G College C S J M University, Kanpur India.

Bacterial Degraders

Due to widespread utilization in many industrial spheres and agrochemicals, N-methyl-2-pyrrolidone (NMP) is a potential contaminant of different surface water ecosystems. Hence, investigation was made into its aerobic microbial degradability in samples of water from a river, wetland area and spring. The results showed that the compound was degradable in all water types, and that the fastest NMP removal occurred in 4 days in river water, while in the wetland and spring samples the process was relatively slow, requiring several months to complete. Key bacterial degraders were successfully isolated in all cases, and their identification proved that pseudomonads played a major role in NMP degradation in river water, while the genera Rhodococcus and Patulibacter fulfilled a similar task in the wetland sample. Regarding spring water, degrading members of the Mesorhizobium and Rhizobium genera were found.
