Abstract

Advances in technology and industrialization, bring with them, their unpleasant partners, pollution and degradation of the environment. The effects on the environment connected with industrial activities are mainly related to the production of industrial wastes. Because of problem associated with pollutant treatment by conventional methods, such as chemical treatment, incineration or landfills, an alternative approach, bioremediation, or the use of organisms for the removal of contamination or pollutants has become a popular option. Bioremediation is considered as one of the safer, cleaner, cost effective and environmental friendly technology for decontaminating sites which are contaminated with wide range of pollutants. As microorganisms show wide range of mechanisms, there are still few mechanisms which are not known, therefore, bioremediation is still considered as a developing technology. Thus, there is an urgent need for us to review and modify the available options for environmental clean-up. The objective of this paper is to conduct a comprehensive review on various indigenous microorganisms extracted from contaminated soil and capable of bioremediation of hydrocarbons present in the sludge.

Abstract

The physico-chemical characteristics of effluents from two different industries, viz. textile and sugar factory, were assessed and the effect of various concentrations (0%, 25%, 50%, 75 % and 100%) on mineral uptake in Triticum aestivum and Raphanus sativus was determined. The study revealed that the germination % of wheat and radish was severely affected by these effluents at higher concentration, where a maximum germination was recorded at 25% effluent concentration. The uptake of iron, phosphate, zinc and copper was found in increasing order and was highest at 100% effluent concentration. The above study reveals the feasibility of using industrial effluent for growing vegetables and crops with proper dilution.

Keywords
