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 mining wastewaters) efficiently removing primary nutrients (C, N, P), heavy metals micropollutants, they do not compete crops arable lands. However, fundamental barriers to industrial application biofuel still include costs algae water which account up 30–40%...
The quest for sustainable production of renewable and cheap biofuels has triggered an intensive search domestication the next generation bioenergy crops. Aquatic plants which can rapidly colonize wetlands are attracting attention because their ability to grow in wastewaters produce large amounts biomass. Representatives Azolla species some fastest growing plants, producing substantial biomass when contaminated water natural ecosystems. Together with evolutional symbiont, cyanobacterium...
ABSTRACT Hexachlorocyclohexane (HCH) has been used extensively against agricultural pests and in public health programs for the control of mosquitoes. Commercial formulations HCH consist a mixture four isomers, α, β, γ, δ. While all these isomers pose serious environmental problems, β-HCH is more problematic due to its longer persistence environment. We have studied degradation by Sphingomonas paucimobilis strain B90 characterized lin genes encoding enzymes from responsible isomers. Two...
A novel polymeric bioflocculant was produced by a bacterium utilizing degradation of n-hexadecane as the energy source. The with bioflocculating activity 87.8 %. hydrocarbon confirmed GC/MS analysis and further supported contact angle measurements for changes in hydrophobic nature culture medium. specific aerobic pathway followed during production utilization process has been proposed. FT-IR, SEM-EDX, LC/MS 1H NMR indicated presence carbohydrates proteins major components bioflocculant....
Currently, only the mass of sub 2.5 μm and 10 particles (PM2.5, PM10) in ambient air is regulated monitored closely, but same increase PM2.5 can cause different degrees health effects cities (sometimes more harmful per unit less polluted cities) (Li et al., 2019). In addition to concentration, other measurement metrics are needed connect particle pollution data effects. our measurements made traffic-influenced environments Helsinki, Finland (a relatively clean city), Delhi-National Capital...
Arthrospira platensis is a cyanobacterium that extensively cultivated outdoors on large commercial scale for consumption as food humans and animals. It can be grown in monoculture under highly alkaline conditions, making it attractive industrial production. Here we describe the complete genome sequence of A. C1 strain its annotation. The contains 6,089,210 bp including 6,108 protein-coding genes 45 RNA genes, no plasmids. information has been used further comparative analysis, particularly...
A bacterium isolated from the activated sludge of an oil refinery Assam, India retained efficient bioflocculating activity through production bioflocculant when it was grown on a crude amended medium void any other carbon source.
The aquatic plants, Azolla filiculoides, and Landoltia punctate, were used as complementing phytoremediators of wastewater containing high levels phosphate, which simulates the effluents from textile, dyeing, laundry detergent industries. Their complementarities are based on differences in capacities to uptake nitrogen phosphate components wastewater. Sequential treatment by L. punctata followed A. filiculoides led complete removal NH4, NO3, up 93% reduction PO4. In experiments where was...
Diesel engines contribute significantly to deteriorating air quality. Tightening legislation has led various technological advances, but developments differ between countries. In India, quality not improved and fine particle (PM2.5) related premature deaths are predicted increase. this study, we characterized the emissions of an Indian-manufactured BS IV (Bharat Stage, comparable Euro emission standards) heavy-duty diesel vehicle studied effects different fuels, fuel blends lubricating oils....
