|Environmental Biotechnology, a sub discipline of Biotechnology is the application of biotechnology used to study the natural environment. It is useful in treating waste water and preventing pollution. Environmental biotechnology is more efficient in cleaning up wastes than conventional methods. Bioremediation is the broadest application employed by Environmental engineers to clean up the environment. They either add the nutrients to the soil at waste site that stimulate the activity of bacteria or add new bacteria to the soil that digest the waste and clean up the site. Bioremediation is an interesting area of Environmental biotechnology; its applications are vast and reliable. Open access (OA) means unrestricted on-line access to peer-reviewed bookish analysis. Open access is primarily meant for educational journal articles, but is in addition provided for a growing vary of theses, book chapters, and learned monographs.

The cheap distribution technology has fueled the open access movement, and prompted every the inexperienced open access self-archiving of non-open access journal articles and so the creation of gold open access journals. Open access to learned analysis is argued to be necessary to the overall public for type of reasons.
