biotechnology environmental issues

Environmental monitoring deals with the as­sessment of environmental quality, essentially by measuring a set of selected parameters on a regular basis. Biomarkers that have potential for use in bio monitoring are: a. Molecular (gene expression, DNA integ­rity), b. Biochemical (enzymatic, specific proteins or indicator compounds), c. Histo-cytopathological (cytological, histopathological). Bioremediation technologies offer a num­ber of advantages even when bioremediation processes have been established for both in situ and ex situ treatment, such as: 1. Factors affecting hydro­carbon biodegradation in contaminated soils can be: a. Biosorptive accumulation of uranium and other radionuclides is of great interest for the development of microbe based bioremedia­tion strategies. In addition, drought resistant crops are being developed by Pioneer, Syngenta, and Monsanto. The mechanisms involved in metal re­moval from waste water include: b. Complexation and solubilisation of metals. The damage caused by oil spills in marine or freshwater systems is usually caused by the water-in-oil emulsion. In this context, source tracking of environmental pollutants and its treatment using biological-based methods is becoming increasingly important, mainly, owing to the accuracy and robustness of such techniques. The risk level posed to human health or environment, 5. It is not a new area of interest, because some of the issues of concern are familiar examples of “old” technologies, such as: composting, wastewater treatment, etc. Find out about Lean Library here, If you have access to journal via a society or associations, read the instructions below. Easily biodegradable organic matter can be treated by this system. Solid waste can be treated by biochemical means, either in situ or ex situ . Heavy metal pollution is usually gene­rated from electroplating, plastics manufactur­ing, fertilizers, pigments, mining, and metal­lurgical processes. <> View or download all content the institution has subscribed to. 5 0 obj endobj Limited degradation, instability of the re­combinant strains of interest in the en­vironment, public concern about deliber­ate or accidental release of genetic modi­fied microorganisms, etc. By continuing to browse If you want Biotechnology & Environmental Issues- Question paper Notes | EduRev Environmental Biotechnology in Pollution Detection and Monitoring: Essay # 9.

The use of microorganisms to remove contami­nants from waste water is largely dependent on wastewater source and characteristics. endobj Biosensors based on a com­bination of a biological sensing element and an electronic signal-transducing element that offer high selectivity, high sensitivity, short- response time, portability and low cost, are ideal for monitoring pollutants in environment. The bio-sorption offers an alternative to the remediation of industrial effluents as well as the recovery of metals contained in other media. Four processes can be considered as acting on the contaminant: A process that physically re­moves the contaminant or contaminated medium from the site without the need for separation from the host medium.
