Different kinds of changes are occurring in the organizations for enhancing the work flow performances. Some of those changes are either continuous or episodic. These changes have been noticed as a catalyst to start the processes of unlearning and new learning at any level of the organization starting from the higher levels up to the grassroots levels. Talking about the change, the concept of the unlearning has primary connection with successful implementation of change. It has been noticeable in the health organization, where people often spend half of their lives not to welcome any new routines and demands of the connected tasks with such a change. As a result a numbers of psychological, social, cognitive and intellectual barriers and hurdles stand firm in unlearning the old ways.It has been observed in health organization that any new learning practices for operating on the new IT devices will have to occur when the unlearning starts at both the organizational and individual levels.

This book is a guide for microbiologists and environmentalists in their incursions into the study of microbial genomes and their role in the degradation of harmful & carcinogenic compounds in the environment. It attempts to organize current affairs in biotechnology through a survey of current methods. During the last few decades environmental pollution control microbiology has become an important field of science due to continuous industrialization in both worlds. So it's a little effort in this rapid expanding field. Aniline is a carcinogenic compound and extensively used in taxtile industry for dying, causing serious threat to the environment with a danger to reach in the food chain as well as in water bodies. Its removal or degradation into harmless compounds is of supreme priority in such areas suffering from taxtile effluents and such. This work will serve as a guide line for the future studies concerning biological or microbial degradation of harmful or carcinogenic compounds like aniline.
