One of the world's seven most notorious weeds, parthenium has dominated five million hectares in India. Biocontrol agents could help, says Rohini Rangarajan Congress grass or parthenium, a native of tropical America, came to India accidentally in 1955. A rapidly growing invasive species, this grass competes well for nutrients and …
The disposal of biomedical waste is a burning problem in developing countries due to scarcity of resources and funds in view of its high cost involved. In this paper, a very cheap, easily available and effective method by using fungus - Periconiella sp. isolated from cow dung was successfully tried, …
Anaerobic digestion of municipal solid waste was carried out in the laboratory at room temperature to assess the bio-energy production from municipal solid waste (MSW) with high total solids content. The total biogas production from the municipal garbage was found to be 3.2 L in 120 days. The results from …
The stomatal response of cassia (Cassia streata L.) and dhaincha (Sesbania rostrata L.) to a coalmine overburden (OB) substrate was studied with a view to rehabilitate such areas. Plants raised in unmined soil were used as controls. The mine OB induced significant increase in stomatal index (SI) with diminished stomatal …
The goal of this study was to assess the phytoremediation potential of transgenic Indian mustard plants. The increase in metal accumulation as a result of these genetic engineering approaches is typically two-to-threefold more metal per plant, which potentially enhances phytoremediation efficiency by the same factor. The significance of this finding …
Bioremediation seems to be a good alternative to conventional clean-up technologies. Bioremediation has advantage over conventional physical and chemical methods such as precipitation, adsorption, electrodialysis and reverse osmosis. The aim of this work was to remove ammonia, nickel and hexavalent chromium from synthetic solutions by bioremediation technique.
Lead from paints, plumbing materials,waste crankcase oil, batteries, etc. pollute the environment and become available to animals as contaminated forage and water.Effective pollution mitigation requires an understanding of the sources and quantities of heavy-metal inputs.In the present study, a lead-responsive biosensor has been made by placing the green fluorescent protein …
Three trees, including Cassia siamea (Cassia), Azadirachta indica (Neem), Holoptelia integrifolia (Holoptelia)belonging to three different families were identified from a manganese mine tailing dump. Manganese content in dump soil and in the stem, green leaves and dry, fallen leaves of the plants was determined. Values were compared with similar samples …
Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of …
Aqueous wastes containing thiocyanate (SCN) are frequently encountered from variety of industrial processes. If improperly managed, these wastes can cause reversible or irreversible impact on the soil and water environment. In the process of developing a microbial technology for the SCN removal from aqueous waste, heterotrophic bacterial consortium's capable of …
Teak leaves (Tectona grandis) abundantly available in India showed high sorption capacity for lead ions and were found efficient for the removal of lead ions from aqueous solutions. The extent of removal was found to be dependent on pH, temperature, concentration of metal ions and the dose of adsorbent.
Chromium is one of the toxic and hazardous pollutants in industrial wastewaters leading to soil contamination. In this study, the feasibility study of remediating chromium contaminated soil using indigenous microorganisms and Pseudomanas fluorescens was evaluated.
Tannery waste disposal problem leads to environmental disharmony, which makes it one of the major industrial pollution facing the country. The tannery industries, release a lot of wastes in the form of liquid (effluent) and solid (sludge). Biological sludge is one of the wastes, which has been utilized for recycling …
Mining is generally followed by a revegetation programme carried by the Forest Department. In such programmes, often exotic plant species are also used along with native tree species. Since the last one and half decades an exotic tree species, Prosopis juliflora has gained tremendous popularity among forest officials due to …
cattle egret which is widely found in India is a natural scavenger. A study from Kerala says that the wetland egret, Bubulcus ibis, can be used as bio-control agent in solid-waste dumping sites. The research has been published in the October 2007 issue of the Zoo's Print Journal (Vol 22, …
Crude oil is of organic origin and is an extremely complex structure of hydrocarbons. Besides carbon, hydrogen, nitrogen and sulphur many other elements are present in crude oil. In oil fields, during drilling, gathering, transporting or in some other operations, some quantity of the crude oil gets spilled over the …
Contamination of chromium is considered a serious environmental pollutant due to wide industrilization. The two largest sources of chromium emission in the atmosphere are from the chemical manufacturing industry and combustion of natural gas, oil and coal. 2007
