Microbial fuel cells (MFC) offer the direct generation of electricity from different sources of waste water, simultaneously accomplishing waste water treatment. MFC converts organic matter to electricity with the help of microorganisms as biocatalysts. While electricity generation using bacteria has been known to be possible for over a decade, only recent studies have shown that mediators are not...
Conventional treatment methods available to remove organic matter are a combination of physical, chemical and biological processes. The limiting nutrients such as nitrates and phosphates are responsible for eutrophication in water bodies. But all the said above existing conventional methods result in negligible reduction nitrogen removal. In this paper, a study is carried out to compare the nitrogen...
Energy crisis is considered to be one of the greatest problems faced by mankind. During the last decade the prices of fossil fuels like oil, coal has risen sharply and there is a continuous depletion of these scarce resources. Hence there is an urgent need to develop and exploit other alternative sources of energy. In this study, biomethanation of vegetable waste with water hyacinth and cow dung was...
Contamination of soil and ground water by Petroleum hydrocarbons is a serious and wide spread environmental problem. The United State Environmental Protection Agency (U.S EPA) has proposed various technological approaches for treating soil contaminated by petroleum hydrocarbons. Among them, bioremediation is a promising technology used to remediate oil contaminated soil that involves indigenous oil...
Solid waste arising from human and animal activities, comprises of countless different materials which are difficult to name them all. Sanitary landfills have been and continue to be an economical method for solid waste disposal especially in developing countries. The solid waste management problem is getting aggravated in the capital city of Kerala, Trivandrum with current generation of around 280–300...
Cell programs as growth and differentiation are determined by the chemical and physical characteristics of the extra cellular matrix (ECM). Changes in the stiffness of the ECM have been reported to affect cell differentiation. On the other hand several cell types spend most of their life moving from anatomical compartment having radically different ECM physical characteristic as for the white blood...
