By Jay Shankar Singh, Gamini Seneviratne

This two-volume paintings is a testomony to the expanding curiosity within the function of microbes in sustainable agriculture and foodstuff protection. Advances in microbial applied sciences are explored in chapters facing subject matters reminiscent of plant-microbe interactions, rhizoremediation and cyanoremediation, and bio-immobilization. quantity II is a suite of analysis findings that invitations readers to check the appliance of microbes in toxins aid, decontamination of agro- and aquatic ecosystems, and remediation of assorted poisonous compounds. hugely readable entries try and shut the data hole among soil microbial institutions and sustainable agriculture.

conventional agricultural administration strategies have relied seriously on software of chemical fertilizers and insecticides; and up to date land use switch practices have resulted in over exploitation of typical assets. concepts defined the following simplify a sophisticated photo of ways microbial groups can enhance the standard of setting and dispose of nutrients shortage within the coming generations. This paintings is an important contribution to investigate during this more and more vital self-discipline of soil sciences, and may entice researchers in microbiology, agriculture, environmental sciences, and soil and crop sciences.

Environmental and Technology Policy in Europe: Technological Innovation and Policy Integration

This booklet comprises six reviews on quite a few nationwide environmental guidelines and setting -oriented expertise coverage platforms in Austria, Denmark, Germany, the Netherlands, Spain, and the uk, sandwiched among this introductory and a concluding bankruptcy. those reports have been performed as a part of the ENVINNO study undertaking, "Towards an Integration of Environmental and Ecology-Oriented expertise coverage: Stimulus and reaction in atmosphere comparable Innovation Networks", which shaped a part of the certain Social and monetary learn (TSER) Programme of Directorate-General XII of the ecu fee, now 1 Directorate-General for study.

Atmospheric Environmental Research: Critical Decisions Between Technological Progress and Preservation of Nature

This can be a longer model of lectures that have been held on the summer season workshop Atmosphiirische Umweltforschung im Spannungsfeld zwischen Technik und Natur (At­ mospheric Environmental learn among expertise and Nature) on the Techni­ sixteen, 1996. We have been more than happy to have Paul J. Crutzen, cal college in Cottbus on July winner of the Nobel Prize for chemistry in 1995, providing the major lecture on glo­ bally altering chemistry within the surroundings.

Endocrine Disrupters: Environmental Health and Policies

In the course of fresh a long time, hundreds of thousands of tonnes of synthetic chemical compounds were produced and published into the surroundings, with little or no defense trying out. a lot of those chemical compounds were chanced on to intervene with the endocrine approach and modulate its functionality. This e-book not just overviews the consequences of endocrine/disrupting ingredients on human health and wellbeing, but in addition addresses the regulatory difficulties from the perspective of overseas corporations, together with the WHO, the european, and the ecu Chlorine undefined.

1977; Schuetz et al. 2003; Smith and Dalton 2004). The enzymes can transform C1-C8 n-alkanes into 1- and 2-­alcohols, terminal alkenes into 1,2-epoxides and diethyl ether into ethanol/ethanal (Colby et al. 1977). Alkanes are hydroxylated mostly at the terminal and sub-­terminal positions, while ring hydroxylation of aromatics occurs primarily at the meta position. The sMMO oxygenates alkenes to epoxides with retention of stereochemistry around the C=C double bond (Smith and Murrell 2009). Chlorinated compounds that are degradable by MMOs include chloroform (Alvarez-Cohen and McCarty 1991a), trichloroethylene (Alvarez-Cohen and McCarty 1991a, b; Henry and Grbic-Galic 1990, 1991; Koh et al.

Methanotrophs can directly or indirectly participate in denitrification, especially in wastewater treatment systems. Modern wastewater treatment systems frequently supplement with costly external carbon sources, such as methanol, to achieve more stringent N discharge limits (Strong et al. 2011). Using methane as a low-cost carbon source to facilitate denitrification would be highly beneficial (Modin et al. 2007). Incorporating methane into the denitrification process was suggested by various researchers in the 1970s (Harremoes and Henze Christensen 1971; Davies 1973; Mason 1977), and four decades later, there have been striking discoveries and substantial progress regarding this coupled process.
