Probiotics as a Potential Alternative for Relieving Peripheral Neuropathies: a Case for Guillain-Barré Syndrome
Trillions of microorganisms form the “natural flora” of the human body. These microorganisms outnumber the host cells 10 to 1, essentially making humans a microbial ecosystem of sorts. Before the advent of the high-throughput sequencing technologies such elusive microorganisms were uncultivable and could not be studied using traditional microbiological techniques. However, since the past decade, with the establishment of the Human Microbiome Project reference database in 2012, research in this area has grown logarithmically (Grogan, 2015).
Production of biodiesel from freshwater microalgae and evaluation of fuel properties based on fatty acid methyl ester profile
Sinha Swapan Kumar, Gupta Arghyadeep, Bharalee Raju
Eleven freshwater microalgal strains of Chlorella sorokiniana BTA4015; Chlorella sp. BTA4032, C. variabilis BTA4036; Chlorella sp. BTA4071; C. variabilis BTA4109; C. variabilis BTA4121; Chlorella sp. BTA4146; Chlamydomonas asymmetrica BTA4028; C. asymmetrica BTA4154; Scenedesmus armatus BTA4076 and Scenedesmus regularis BTA4112 were isolated from northeast India and identified through internal transcribed spacer 2 region sequence alignment.
Purification and characterization of exopolysaccharide bioflocculant produced by heavy metal resistant Achromobacter xylosoxidans
Subudhi Sanjukta,Bishta Varsha, Batta Neha, Pathak Mihirjyoti, Devi Arundhuti, Lal Banwari
Optimization of process parameters enhanced bioflocculating activity of 'Achromobacter xylosoxidans strain TERI L1' from 75% to 83.3% in absence of heavy metals, which decreased to 73% in presence of multi-metals. 'TERI L1' could adsorb 90% of multi-metals when grown in presence of 1250 mg L(-1) Zn, 2 mg L(-1) Cd, 30 mg L(-1) Pb, 200 mg L(-1) Ni and 90 mg L(-1) Cu and could adsorb 1100 mg L(-1) of Pb when grown in presence of 1500 ppm lead nitrate. The bioflocculant was purified and characterized. Bioflocculant yield was 5 g L(-1).
Climate cooperation has been discussed for long, but little is achieved on the ground in South Asia. The Paris Agreement is an opportunity to renew the commitments.

Despite the historical priority to grid-based electrification in South Asia, two out of every five people in the region still live without access to electricity. Due to various limitations of conventional grid-based rural electrification, as brought out by a number of studies and reports, demand for alternative models such as renewable energy based off-grid and distributed generation solutions are gaining increasing attention globally.

Ground level ozone is emerging as a pollutant of concern in India. Limited surface monitoring data reveals that ozone concentrations are well above the prescribed national standards. This study aims to simulate the regional and urban scale ozone concentrations in India using WRF-CMAQ models. Sector-specific emission inventories are prepared for the ozone precursor species at a finer resolution (36 × 36 km2) than used in previous studies.

Zinc oxide (ZnO) nanoparticles are used for the synthesis of various materials. The nanoparticles, when entering into the environment, affect aquatic life. Their antibacterial properties deter the biological treatment process of wastewater treatment plants. The study focuses on the effectiveness of ultrafiltration (UF) membranes for the removal of ZnO nanoparticles. In this study, a commercial membrane was used for the separation of ZnO nanoparticles in the presence of natural organic matter (NOM) and alkalinity.
Sustainable Development: A Critical Review of Construction and Demolition Waste Management Rules 2016
Manuja Sourabh, Siddiqui Faisal Zia, Breu Sandra, Tripathi Raj Deep
The Ministry of Environment, Forest and Climate Change(MoEFCC), Government of India has notified the Construction and Demolition Waste Management (CDWM) Rules in March, 2016. The new notification supersedes the existing Municipal Solid Waste (Management and Handling) Rules, 2000 which was addressing limited issues related to Construction and Demolition (C&D) waste. This paper summarises the salient features of the gazette notification and discusses the shortcomings in the existing CDWM rules?
In the literature on sustainability of agriculture, both labourers and workers are conspicuously absent. Here, the sustainability of agriculture has been defined in terms of whether the farm household in question is able to yield an energy surplus when its members and the animals in its possession are obtaining an adequate ‘energy income’ or Calorie intake. To evaluate the sustainability of 590 farming households in the state of West Bengal, India, during 2004–5, four progressively stricter definitions of sustainability have been proposed, defined and applied.
More than 20% of the electricity generated in India is lost to rampant thefts. Drawing data from 28 states of India over a time span of ?ve years (2005–2009, this paper examines the role played by socio-eco-nomic and governance factors in determining the extent of electricity thefts in Indian states.
