In recent years, both processes have seen remarkable developments in terms of process design and control. Algae and plants proved to be suitable to absorb nitrogen, phosphorus, sulphur, and many minerals and metals from the environments. Because biotechnological processes, once set up, are considered cheaper than traditional methods and changes in production processes will not only contribute to environmental protection, but also help companies save money and continuously improve their public image. <> Bio-waste is generated from various anthropogenic activities (households, agriculture, horticulture, forestry, waste water treatment plants), and can be categorized as: manures, raw plant matter, process waste. These are as follows: 1. Metal ions can bind to cells by different physiochemical mechanisms, depending on the bacterial strain and environmental conditions. By continuing, I agree that I am at least 13 years old and have read and agree to the. Bio-treatment can be used to detoxify waste streams at the source-before they contaminate the environment-rather than at the point of disposal. To reduce the quantity and maximize the quality of effluent waste streams that are created during production of goods. In addition, bio augmentation involves the deliberate addition of microorganisms that have been cultured, adapted, and enhanced for specific contaminants and conditions at the site. As a recognition of the strateg ic value of biotechn ology, i n-tegrated plans are formulating and implementing in many . a. g. Design waste water treatment based on decentralized sanitation and re-use. You can be signed in via any or all of the methods shown below at the same time. <> <> The signal may be electrical or in the form of a dye that changes colour. It is also known that the activity of bacteria and fungi able to oxidize hydrocarbons could be improved by supplementation with various nutrients (sources of nitrogen and phosphorous). It is concerned with the application of biotechnology as an emerging technology in the context of environmental protection, since rapid industrialization, urbanization and other developments have resulted in a threatened clean environment and depleted natural resources. The co-fermentation of separately collected biodegradable waste with agricultural and/or industrial solid and liquid waste, c. Co-fermentation of separately collected biodegradable waste in the digesting towers of municipal waste treatment facilities. Do check out the sample questions Biosorptive accumulation of uranium and other radionuclides is of great interest for the development of microbe based bioremediation strategies. More recently, environmental monitoring programmes have, apart from chemical measurements in physical compartments, included the determination of contaminant levels in biota, as well as the assessment of various responses of biological/ecological systems. However, the use of DNA technology in pollution control showed to have some disadvantages and limitations such as: a. Multistep pathways in xenobiotics biodegradation. The occurrence of optimal environmental conditions to stimulate bio-degradative activity, b. 5. The formation of public perceptions of science is a very complex and problematic process, but a major factor is the information that is available and presented most frequently to the public. Nowadays, temporal and spatial changes in selected biological systems/parameters can and are used to reflect changes in environmental quality through bio-monitoring. Solid Waste Bio-Treatment 6. The prime controlling factors are air (oxygen) availability, moisture content, nutrient levels, matrix pH, and ambient temperature. One of the most significant key aspects in the design of biological wastewater treatment systems is the microbial community structures in activated sludge’s, constituted from activated sludge floes, which enclose various microorganism types. d. Fermentation of the residual mixed waste fraction within the scope of a mechanical- biological waste-treatment concept. Metals from waste water such as iron, copper, cadmium, nickel, uranium can be mostly complexed by extracellular polymers produced by several types of bacteria (B. licheniformis, Zooglearamigera). c. Designing strains for enhanced biodegradation. Anaerobic treatment of wastewater does not generally lead to low pollution standards, and it is often considered a pre-treatment process, devoted to minimization of oxygen demand and excessive formation of sludge. <>>> Issues of public concern over agricultural and environmental biotechnology were identified from opinion surveys, the popular press and technical/regulatory sources.

Issues of public concern over agricultural and environmental biotechnology were identified from opinion surveys, the popular press and technical/regulatory sources. Exploitation of interactions with other technologies. Sometimes, immobilization can be a major problem in remediation because it can lead to aged contamination and a lot of research effort needs to be applied to find methods to turn over the process. Evolutionary and genomic approaches to biodegradation.
