Pollution in soil is caused by persistent toxic compounds, chemicals, salts, radioactive materials, or disease-causing agents, which have adverse effects on plant growth and animal health. Students following this career path typically pursue degrees in ecology or environmental engineering. To comply with this trend, industrial development has to change to sustainable style from degradative type and for such a purpose cleaner technologies have to be adopted. Environmental biotechnology in particular is the application of processes for the protection and restoration of the quality of the environment. While the above is a clear example of how scientists are already genetically modifying bacteria, bacteria can also be used to help the process of genetic engineering of plants. Our mission is to provide an online platform to help students to share notes in Biology. These are currently being used to remove pharmaceutical drug residue from wastewater, which is a big problem because it harms the environment and has even been found to disrupt sex hormones and organs in fish. Environmental scientists and specialists, including biotechnologists, are employed nationwide. Pollutants also come from other sources. Environmental impacts of biotechnologies are considered through two venues: successful biological treatment processes and biotechnologies in non-environmental applications. This process is used for treatment and removal of dissolved and biodegradable wastes, such as organic chemicals, petroleum refining wastes textile wastes and municipal sewage. 1. People have been harnessing biological processes to improve their quality of life for some 10,000 years, beginning with the first agricultural communities. The aim of environmental biotechnology is to prevent, arrest and reverse environmental degradation through the appropriate use of biotechnology in combination with other technologies, while supporting safety procedures as a primary component of the programme. The use of living microorganism to degrade environmental pollutants is called, 3. Geographic Information Systems have improved the management and understanding of geographical areas. Cows (with human genes) More recently in 2011 Chinese scientist have been breeding cows genetically engineered with genes from human beings to produce milk that would be the same as human breast milk. the book introduces environmental biotechnology as a tool to progress towards sustainable development goals and covers green technologies such as bio-plastics, third generation hybrid. Environmental biotechnology aims at the protection of the environment and purification of the environment from toxic contaminants and helps in the prevention of the degradation of precious natural resources such as soil, air, water and mineral resources. Addition of nutrients, terminal electron acceptors (O2/NO2), temperature, moisture to promote the growth of a particular organism may be required for the microbial activity in the polluted site. Biological off-gas treatment is generally based on the absorption of the VOC in the waste gases into the aqueous phase followed by direct oxidation by a wide range of voracious bacteria, which include Nocardia sp. Pollution control by genetic engineering is likely to work best when pollutants are a known mixture of relatively concentrated organic compounds that are related to each other in structure, where conventional alternative organic nutrients are absent, and when there is no competition from indigenous microorganisms.

Education and training requirements vary greatly depending on the type of position. In the USA some genetically modified bacteria have been approved for bioremediation purposes but large scale applications have not yet been reported. A river drains the lake at a rate of 22.64 $m^{3} \cdot s^{-1}$. The most prominent area of biotechnology is the production of therapeutic proteins and other drugs through genetic engineering. [3] Contents This can be effected in a number of ways, either in situ or by mechanically removing the soil for treatment elsewhere. While careers in biotechnology have typically required Master's and doctoral degrees, the rapid growth of the field has opened up opportunities for those with bachelor's and associate's degrees. It does not store any personal data. a) the use of microbes to clean up the environment, c) the study of benefits and hazards associated with GMMs, 2. In 1995, the Environmental Protection Agency (EPA) gave clearance for development of transgenic corn seed, cotton seed, and seed potatoes that contain the genetic material to resist certain insects.
