A novel polymeric bioflocculant was produced by a bacterium utilizing degradation of n-hexadecane as the energy source. The bioflocculant was produced with a bioflocculating activity of 87.8%. The hydrocarbon degradation was confirmed by gas chromatography-mass spectrometry analysis and was further supported with contact angle measurements for the changes in hydrophobic nature of the culture medium. A specific aerobic degradation pathway followed by the bacterium during the bioflocculant production and hydrocarbon utilization process has been proposed.

Surface level ozone is one of the important air pollutants. It is formed by the reaction of atmospheric pollutants in the presence of sunlight. The surface ozone shows temporal and spatial variations in the country. The levels are maximum during summer and minimum in monsoon seasons. The levels are maximum during daytime and minimum during night or early morning. In India, surface ozone levels are above the recommended threshold of 8 hour average of 100 μg/m3 for air quality monitoring at various stations. Exposure to high levels of surface ozone causes number of health problems.

Bioelectrochemical enhancement of direct interspecies electron transfer in upflow anaerobic reactor with effluent recirculation for acidic distillery wastewater

| 2017

Methane production in the upflow anaerobic bioelectrochemical reactor (UABE) treating acidic distillery wastewater was compared to the upflow anaerobic sludge blanket reactor (UASB), and the electron transfer pathways for methane production were also evaluated in the effluent recirculation. The methane productions from reactors were influenced by the low pH of influent wastewater. However, the methane production rate and yield of the UABE were 2.08 L/L.d and 320 mL/g CODr, which were higher than the UASB.

Microalgae have shown clear advantages for the production of biofuels compared with energy crops.Apart from their high growth rates and substantial lipid/triacylglycerol yields, microalgae can grow in wastewaters (animal, municipal and mining wastewaters) efficiently removing their primary nutrients (C, N, and P), heavy metals and micropollutants, and they do not compete with crops for arable lands.

An Assessment of Ground Water Potential for state of Kerala, India: A Case Study

The southern state of Kerala in India, known as ‘God’s Own Country’, is blessed with plenty of water resources that include chains of backwater bodies, rivers, reservoirs, lakes, ponds, springs and wells. Although, the state receives abundant rainfall throughout the year, the region’s topography and soil characteristics, combined with rapid urbanization are causing significant stress to its ground water level. Therefore, it has become imperative for researchers, scientists, administrators, and policy-makers to analyze the present ground water situation of the state.

Novel Targets and Advancements 18 in Drug Discovery: The Case of HIV-AIDS

Nihar Ranjan, Umesh Kumar, and Sunil K. Deshmukh
| 2017

Since the very first report of acquired immune deficiency syndrome (AIDS) in the early 1980s in the United States, a number of advancements have taken place both in the structural and functional aspects of the human immunodeficiency virus (HIV) life cycle as well as anti-HIV drug design. While new drugs have come to the market and combination therapies have increased life expectancy, resistance and viral mutations have mandated introduction of new drugs in the market. Apart from two main classes of HIV inhibitors (reverse transcriptase and

In this study, an ecofriendly and economically viable waste management approach have been attempted towards the biosynthesis of agriculturally important nanoparticles from jarosite waste. Aspergillus terreus strain J4 isolated from jarosite (waste from Debari Zinc Smelter, Udaipur, India), showed good leaching efficiency along with nanoparticles (NPs) formation under ambient conditions. Fourier-transform infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM) confirmed the formation of NPs.

​​Nonribosomal Peptides from Marine Microbes and Their Antimicrobial and Anticancer Potential.

| 2017

Marine environments are largely unexplored and can be a source of new molecules for the treatment of many diseases such as malaria, cancer, tuberculosis, HIV etc. The Marine environment is one of the untapped bioresource of getting pharmacologically active nonribosomal peptides (NRPs). Bioprospecting of marine microbes have achieved many remarkable milestones in pharmaceutics.

Tuberculosis is an endemic disease of the poverty ridden, undernourished and over populated countries of the world. It is also a systemic disease that is extremely dependent on the physiology of the system it invades and thus varies signifi cantly from person to person. New developments in the treatment of this d isease have rarely percolated down to the larger sections of the under privileged in our societies. The need for highly active, long acting, yet less expensive drugs against Multi-Drug Resistant (MDR) Mycobacterium tuberculosis still exists.
