Anthropogenic activity has clearly altered the N cycle contributing (among other factors) to climate change. This book aims to provide new biotechnological approach representing innovative strategies to solve specific problems related to the imbalance originating in the N cycle. Aspects such as new conceptions in agriculture, wastewater treatment, and greenhouse gas emissions are discussed in this book with a multidisciplinary vision. A team of international authors with wide experience have contributed up-to-date reviews, highlighting scientific principles and their environmental importance and integrating different biotechnological processes in environmental technology.

Prof. Jesus Gonzalez-Lopez Head of the Environmental Microbiology and Engineering Research Group (University of Granada), has extensive experience in water technology and environmental research. He has 396 publications, with h-index of 53, 12 patents and is consultant for companies such as Veolia, SACYR and Repsol-YPF, among others. He has coordinated EU projects (11 framework programmes, 3 training networks, cost actions, and 1 Marie Curie grant holders, an ASEAN-EU environmental biotechnology network program).

Dr. Alejandro Gonzalez-Martinez is an assistant professor in the Department of Microbiology at the University of Granada. Among the researcher’s scientific achievements, he has 70 peer-reviewed publications, an H-index of 21 and 1 patent. He has been working in several European public-funded R&D projects (i.e Life+, Grundvig, FP7, Leonardo da Vinci-Transfer of Innovation) and has cooperated with International private companies (i.e Hidralia, Sacyr-Valoriza, Cetaqua, CLH, Ekokem, Fortum, among others).
