Application of microarray technology to environmental samples though known broadly are neither widely understood nor studied in detail. With increasing awareness of environmental status and for sustainable development without environmental degradation much care is being taken particularly in respect of analyzing microbial community composition and function in natural environments. "Environmental applications of microarray technology" deals with all aspects, provide an in-depth description of the basis and principles of microarray-based technologies. This book thus covers all the aspects of technology and its wide applications.
