Insight Into

Geothermal springs are model ecosystems to systematically investigate microbial biogeography as they i) represent discrete, homogenous habitats; ii) are abundantly distributed across multiple geographical scales; iii) span broad geochemical gradients; and iv) have simple community structures with reduced metazoan interactions. Taking advantage of these traits, we undertook the largest known consolidated study of geothermal ecosystems (http://1000springs.org.nz) to determine factors that influence biogeographical patterns. Rigorously standardised methodologies were used to measure microbial communities, 46 physicochemical parameters, and metadata from 1,019 hotspring samples across New Zealand. pH was found to be the primary influence on diversity in springs < 70 °C with community similarity decreasing with geographic distance. Surprisingly, community composition was dominated by two genera (VenenivibrioandAcidithiobacillus) in both average relative abundance (11.2 and 11.1 %) and prevalence (74.2 and 62.9 % respectively) across physicochemical spectrums of 13.9 – 100.6 °C and pH < 1 – 9.7. This study provides an unprecedented insight into the ecological conditions that drive community assembly in geothermal springs, and can be used as a foundation to improve the characterisation of global microbial biogeographical processes.

India is a developing nation and is dependent on its natural resources for growth and development. Water, being one of the vital natural resource, must be used judicially for the sustainable development. Present study focuses on the analysis of physicochemical parameters (pH, Turbidity, Alkalinity, Total Hardness, Total dissolved solids, Conductivity, Chloride, Sulfate, Fluoride contents) of ground water and surface water in Kota City (Rajasthan). The study shows the adverse impact of exploitation and urbanization on water resources of Kota City (Rajasthan). Some physicochemical parameters exceed the desirable limits as defined by WHO and Indian Standards in the selected sites. The level of pollution in ground water and surface water of Kota City is increasing due to urbanization.

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.

Background: Sneha Kalpana is one among the several highly established Kalpana of Ayurvedic system of medicine. Many types of Taila Kalpana are mentioned in Ayurvedic classics and used effectively in therapeutic practice. Tila Taila is the most commonly using Taila. However Narikelataila, Erandataila, Sarshapataila, etc, are also used in special conditions. It is interesting to note that certain preparations are available in the market based on both TilaTaila and Narikela Taila. This is an attempt to comparatively evaluate the formulation Dhutturadi Taila prepared in Tila Taila and Narikela Taila as the bases. Dhutturadi Taila mentioned in Sahasrayogam is taken for the present study. Objectives: To comparatively analyse Dhutturadi Taila samples with classical and advanced analytical techniques. Materials and Methods: Dhutturadi Taila was prepared using two media i.e. Narikela Taila and Tila Taila. Both Taila samples were comparatively analysed with suitable physicochemical parameters and advanced instrumental methods of analysis. Conclusion: As per the existing result it seems that more amount of marker components are extracted into Tila Taila medium when compared with Narikela Taila.
