“…In the last years, a lot of legislative actions for environmental pollution control have been grown due the social concern in this area ( on the basis of the transducing element, they can be named as electrochemical, optical, piezoelectric or thermal sensors; according to the bio recognition principle, biosensors are classified into antibodies and antigens, enzymatic, non-enzymatic, whole-cell and nucleic acids biosensors (Marazuela & Moreno-Bondi, 2002;Rodriguez-Mozaz et al, 2006).…”

A number of species of Haloferax genus (halophilic Archaea) are able to grow micro aerobically or even anaerobically using different alternative electron acceptors such as fumarate, nitrate, chlorate, dimethyl sulphoxide, sulphide and/or trimethylamine. This metabolic capability is also shown by other species of the Halobacteriaceae and Haloferacaceae families (Archaea domain) and it has been mainly tested by physiological studies where cells growth is observed under anaerobic conditions in the presence of the mentioned compounds. This work summarises the main reported features on anaerobic metabolism in the Haloferax, one of the better described haloarchaeal genus with significant potential uses in Biotechnology and Bioremediation. Special attention has been paid to denitrification, also called nitrate respiration. This pathway has been studied so far from KEY WORDSHaloarchaea, denitrification, anaerobic metabolism, Nox emissions, bioremediation.

Infectious diseases are one of the greatest threats to animal and human population living in the developing world. These diseases have capacity to instigate in a small area and then open out very fast to the rest of the world and causing a heavy pandemic situation, for example; avian influenza pandemic. Such diseases infect large masses of population and may lead to loss of lives and also incur huge economic losses. Therefore, the best way to control these diseases is by diagnosing it at a very primary level and taking necessary precautionary measures so as to avoid the spread. Since last few years, the diagnostic approach has changed from tedious molecular biological techniques, to easy and rapid diagnostic techniques. Nanotechnology has extended the molecular diagnostics limit to nanoscale. These developed techniques do not require sophisticated laboratories and expert personnel, and hence are a cheap diagnostic approach. These assays can also be performed at the field level where the patient is present and get the results there itself. Hence, they are also called as pen side test or lab on chip diagnostic assays. The biological tests using nanotechnology become quicker, more flexible and more sensitive. These techniques have greatly influenced the diagnostic approach in the veterinary as well as medical field. Especially in the developing countries such as India, where the laboratory services are not

Optical biosensors for food quality and safety assurance—a review

et al. 2011

View full text Add to dashboard Cite

Food quality and safety is a scientific discipline describing handling, preparation and storage of food in ways that prevent food borne illness. Food serves as a growth medium for microorganisms that can be pathogenic or cause food spoilage. Therefore, it is imperative to have stringent laws and standards for the preparation, packaging and transportation of food. The conventional methods for detection of food contamination based on culturing, colony counting, chromatography and immunoassay are tedious and time consuming while biosensors have overcome some of these disadvantages. There is growing interest in biosensors due to high specificity, convenience and quick response. Optical biosensors show greater potential for the detection of pathogens, pesticide and drug residues, hygiene monitoring, heavy metals and other toxic substances in the food to check whether it is safe for consumption or not. This review focuses on optical biosensors, the recent developments in the associated instrumentation with emphasis on fiber optic and surface plasmon resonance (SPR) based biosensors for detecting a range of analytes in food samples, the major advantages and challenges associated with optical biosensors. It also briefly covers the different methods employed for the immobilization of bio-molecules used in developing biosensors.
