Isolation and enrichment of bacteriophages by membrane filtration immobilization technique.(Current protocol in cell Biology)
(Ghugare, G. S.,Nimkande, V
,e41. ,,,Year : 2017)
|
The method described here enables rapid bacteriophage isolation and enrichment of host-specific bacteriophages from an environmental sample. This is achieved by using a simple 0.45-µm Milli pore membrane where a specific host is immobilized on the membrane and a sample suspected of containing bacteriophages is exposed to the immobilized cells with the help of a membrane ltration unit. This filtration step facilitates host-specific interaction of bacteriophages with the host and maximization of this interaction using a classic membrane filtration method.Under the effect of vacuum from a vacuum pump, a filter assembly provides a chance for every bacteriophage in the sample to interact with the specific host on the membrane filter. Our technique allows retaining specific bacteriophages on the membrane along with its host cells via adsorption; these adsorbed bacteriophages (along with their hosts) on a filter disc are then enriched in regular nutritive broth, tryptone soya broth (TSB), by incubation. With help of a plaque assay method, host-specific phages of various bacterial species can be isolated, segregated, and enriched

A Mechanical Automatic Urinal-Toilet Flusher for Swach Bharat Mission(Procedia Environmental Sciences)
(,35 ,,185-192,Year : 2016)
|
A flush urinal-toilet disposes human waste by using water through a drainpipe to another location. A series of urinal-toilets are fitted in offices, malls, multiplexes, educational institutions, bus railway stations, airports, commercial complexes, stadia and other public places. Most have manual flushing systems like push button, trigger, pull chain, etc. however, use of such manually operated flush can spread germs and bacteria when contacted and thus users avoids to flush or lead to wastage of water if used. Now a day’s laser or infrared sensor operated flushes is also used in the places of high commercial value and importance but are expensive and required continuous O&M. Therefore, the sanitary facility may remain un-flushed leading to unhygienic conditions and foul smell. Thus need for a low cost automatic flushing apparatus which can flush the right-controlled amount of water and avoid direct contact thus conserving water as well as maintaining personal hygiene and sanitationThe present invention relates to a specially designed mechanical automatic urinal-toilet flusher and a mechanism thereof, which utilizes the weight load/pressure of the person using the urinal-toilet for automatic flushing the urinal- toilet with the specified or measured quantity of water to prevent odors, soil drain and scale buildup. It ensures the compulsory, regular and un-intentional flushing of the urinal-toilet without any direct hand contact of the user to the flush and also conserve water at the same time is simple and cheap, which can be fitted-retrofitted to new as well as existing water pipe line of the urinal-toilets.

Carbon footprint: current methods of estimation(Environmental Monitoring and Assessment)
(Divya Pandey, Madhoolika Agrawal
,,,178,Year : 2011)
|
"Increasing greenhouse gaseous concentration in the atmosphere is perturbing the environment to cause grievous global warming and associated consequences. Following the rule that only measurable is manageable, mensuration of greenhouse gas intensiveness of different products, bodies, and processes is going on worldwide, expressed as their carbon footprints. The methodologies for carbon footprint calculations are still evolving and it is emerging as an important tool for greenhouse gas management. The concept of carbon footprinting has permeated and is being commercialized in all the areas of life and economy, but there is little coherence in definitions and calculations of carbon footprints among the studies. There are disagreements in the selection of gases, and the order of emissions to be covered in footprint calculations. Standards of greenhouse gas accounting are the common resources used in footprint calculations, although there is no mandatory provision of footprint verification. Carbon footprinting is intended to be a tool to guide the relevant emission cuts and verifications, its standardization at international level are therefore necessary. Present review describes the prevailing carbon footprinting methods and raises the related issues."

Common Effluent Treatment Plants for Heterogeneous Cluster of Industries and Its Performance(National Journal of Life Sciences)
(Kishore Malviya and M. Suresh Kumar
, 11(2),,187-190,Year : 2014)
|
It has been almost over two decades since the concept of Common Ef?uent Treatment Plant (CETP), has been established successfully in India. CETPs have worked well for the cluster of similar type of Industries; however, the CETPs catering to a cluster of heterogeneous industries are still facing a problem of under performance resulting in regulatory issues. To address this problem, a CETP treating combined wastewater from heterogeneous cluster of 175 industries manufacturing different products, was studied. The CETP's performance and related problems were assessed by collecting wastewater samples from different stages of treatment and a detailed physico-chemical and bio-chemical analysis of these wastewater samples. The treat ability studies were conducted to address these problems, which were mostly pertaining to optimization of chemical additions in the primary treatment stages and addition of nutrients in the activated sludge process. The operational parameters were reset on the basis of outcome of the treatability studies and the performance of the CETP was again assessed after a period of 45 days of operation at reset operating conditions. The performance of the CETP substantially improved and the ?nal discharge could conform to the regulatory standards.

Domestic use of cooking Fuel in India: A Review on Emission Characteristics and Associated Health concerns(Asian Journal of Chemistry)
(Pervez S., Verma Madhuri, Dewangan S., Dipanjali Majumdar,30(2),,235-245,Year : 2018)
|
One out of every three Indians use biomass fuels such as wood, animal dung and coal cake, crop residues as their primary domestic energy source. About 23% and 61% of urban and rural Indian households, respectively, rely on traditional stoves (Chullah) for cooking practices. Household air pollution (HAP), which contains solid fuel burning emissions prominently, is reported to claim 4.3 million premature deaths yearly in developing country. But most of review studies to address air pollution scenario in India are focused on outdoor environments; major reason to review the current knowledge on emission estimates from household biomass burning and associated impacts on indoor air and human health. This review intends to critically discuss the variability associated with emission estimates and impacts of household air quality in different parts of India as presented in several research works, published during 2001-2015. About 27% and 11% increase in PM2.5 and PM10 has been observed in Indian house-indoors during the assessment period. Emission factors, emission budgets of aerosol fractions, carbonaceous matter and other chemical components for household biofuel burning emissions were also summarized for the period of 2001-2015. Health effects studies due HAP in India were also summarized and discussed. Improvement in ventilation system and modification in the pattern of fuels may contribute to reduce the effect of the pollution on national health. As there are no specific regulations or acts for controlling of HAP in India, urgent need is felt for implementing the strategies to create public awareness.

Reaction mechanisms and rate constants of waste degradation in landfill bioreactor systems with enzymatic-enhancement.(Bioresource Technology)
(Jayasinghe,P.A., Hettiaratchi, J.P.A.,Mehrotra, A.K.,&Kumar,162,,279-282,Year : 2014)

Augmenting leachate before recirculation with peroxidase enzymes is a novel method to increase the available carbon, and therefore the food supply to microorganisms at the declining phase of the anaerobic landfill bioreactor operation. In order to optimize the enzyme-catalyzed leachate recirculation process, it is necessary to identify the reaction mechanisms and determine rate constants. This paper presents a kinetic model developed to ascertain the reaction mechanisms and determine the rate constants for enzyme catalyzed anaerobic waste degradation. The maximum rate of reaction Vmax for MnP enzyme-catalyzed reactors was 0.076 gTOC/gDS.day. The catalytic turnover number kcat of the MnP enzyme-catalyzed was 506.7 per day while the rate constant k of the un-catalyzed reaction was 0.012 per day.

Urbanization, population and economic growth in Indian megacities like Delhi have resulted in an increase in energy and transportation demand leading to severe air pollution and related health impacts, as well as to the rapid growth in the greenhouse gas emissions. In this study, an integrated assessment of air quality and climate policiesfor Indiancities –withaparticularfocuson NationalCapital TerritoryofDelhi,hasbeencarriedout.We have developed emission inventory of air pollutants and greenhouse gases for the base year (2010) and evaluated the impact ofcurrent policieson emission projections by2030 in the business-as-usual scenario. Emissions of coarse and ?neparticulate matter areprojected to be51% and 15%higher in2030 as compared to present. As the current legislations do not indicate progress towards the achievement of the Indian National Ambient Air Quality Standards in Delhi, we explored the e?ectiveness of additional emission control strategies with either advanced end-of-pipe emission controls or low carbon policies. Relative to the baseline scenario, the set of alternativepolicystrategieswouldreduceemissionsrapidlyin2030.Theresultsrevealedthatairqualitypolicies under various scenarios could also have co-bene?ts of reducing carbon emissions. At the same time, the results suggest that low carbon policies would be more e?cient to cut emissions as compared to advanced end-of-pipe emission control policies. However, their implementation could be limited by the availability of clean fuels. In the climate policy scenario, carbon emission in 2030 is estimated to decrease by 19% relative to baseline. Additional controls combined with low carbon policies like controlling non-industrial emissions create an opportunity to further enhance the scope for co-bene?ts and to attain the air quality standards in Delhi.

3D printing of high surface area ceramic honeycombs substrates and comparative evaluation for treatment of sewage in Phytorid application(Journal of Water Process Engineering)
(Papiya Biswas,Sirisala Mamatha, Kezil Varghesea, Roy Johnsona, Ritesh Vijay, Rakesh Kumar,Vol 37 ,,101503 ,Year : 2020)

Substrates properties play an important role in immobilization of bio-organisms and hence in optimizing design of the bioreactor to maximize the performance. Highly flexible 3D printing process based on virtual Computer Aided Design (CAD) is used for producing honeycomb substrates with desired properties. Clay based honeycomb with square, triangular and hexagonal configurations are 3D printed in order to achieve substrates with pre-designed geometrical surface areas. Laboratory reactors were fabricated with engineered properties using 3D printed honeycombs and a combination of honeycombs and commonly used stones for performance evaluation. Additionally, reactor based on commonly used gravel stones also fabricated for sake of comparison of performance. In order to elucidate the performance, sewage mix was fed into the reactors and the space velocity of all the three reactors were maintained at 0.041 h?1. The sewage before and after treatment was tested for the performance markers such as pH, TSS, BOD and COD. Treated water met the stipulated standards prescribed by American Public Health Association with respect to all parameters studied. Though the difference in the performance of the reactors was marginal, with honeycombs a substantial reduction in the weight of the reactor can be accrued along with high mass transfer due to low pressure drop which can be attributed to the inherent higher surface to volume ratio. Further, by engineering the surface porosity of the honeycombs, it is possible reduce TSS as demonstrated in this study. These advantages offer flexibility in scaling up the reactors for larger capacities for de-centralized requirements.

Hydrodynamic and Advection-Dispersion Simulation of Cool Seawater Discharges from an LNG Facility(Indian Journal of Geo-Marine Sciences)
(Ankit Gupta, Ritesh Vijay, Rakesh Kumar,49,,7-14,Year : 2015)
|
The impact of cool seawater discharge in the coastal waters from a Liquefied Natural Gas (LNG) plant has been simulated using MIKE21. In this work, hydrodynamics conditions of the coastal waters were calibrated and corroborated to predict the cool seawater discharge under two plant design scenarios by selecting flow rate 15 m3 /s and 10 m3 /s with a temperature drop of 5 °C and 7 °C, respectively. The simulations were carried out under different scenarios, to arrive at the best possible case to minimize the potential impact on the coastal environment. Both the simulated scenarios complied with the available World Bank guidelines for LNG facilities. However, the designed scenario of flow rate 10 m3 /s with a temperature drop of 7 °C between inlet and outlet presents a better choice as it reduces the pumping power of seawater intake. As there are no Indian guidelines for cool seawater discharges from LNG plant, the present work can support the policymakers and regulators to formulate coherent discharge standards.

Root transcripts associated with arsenic accumulation in hyperaccumulator Pteris vittata(Journal of Biosciences)
(Rasika M Potdukhe, Priyanka Bedi, Bijaya K Sarangi, Ram A Pandey and Sanjog T Thul
, 431,,105–115 ,Year : 2018)
|
Hyperaccumulation of arsenic (As) by brake fern Pteris vittata has been described as an important genetic trait that provides an option for development of a sustainable phytoremediation process for As mitigation. Accumulation of very high concentration of arsenic in above-ground tissues may be the result of arsenic vacuole compartmentalization, but the mechanism(s) of arsenic uptake and transport by underground tissues are largely unknown. In this study, we made an attempt towards understanding the molecular mechanism of As hyperaccumulation in this plant. A time-dependent As accumulation study indicates an exponential accumulation of As from 7 to 30 days of arsenic exposure in fronds, and day 3–7 in roots. Root transcriptome analysis identified 554,973 transcripts. Further, subsets of 824 transcripts were differ- entially expressed between treated and control samples. Many of the genes of critical As-stress response, transcription factors and metal transporters, biosynthesis of chelating compounds involved in uptake and accumulation mechanisms were identified. The genes that were highly expressed such as cysteine-rich RLK, and ABC transporter G family member 26 needs further studies along with arsenite transmembrane transporter. The analysis of generated transcriptome dataset has provided valuable information and platform for further functional studies.
