Microbes in harsh environment
The situation of microbes in the natural habitat with complex organic and inorganic constituents is very akin to the plight. Every organism is coping up with the problem of becoming fittest for survival. To stay viable in all such harsh condition adaptation is the key factors for every individual organism {79(P)}. Understanding adaptation mechanisms of microbes sustaining in harsh environments were opened up a new research way to employ microbes in process of environmental remediation. It is well understood that, metals like cobalt, copper, manganese, molybdenum, iron and zinc are key components for normal physiological functioning of every living form at desired concentrations scientific investigations focused on understanding microbial behaviour with essential and non-essential metals from the recent decades, opened up new research area ‘Metal Biotechnology’ to deal with risk posed by widespread environment pollutions {19P, 17P,}. By enchasing metabolic potentials of microbes termed as bioremediation. Microbes usually have central role in phenomenon of bioremediation, with their pre-existing proficiencies to degrade or to convert xenobiotic compounds into less toxic forms (Kapri et al., 2011in review). In this review the effort has been made to document the research finding in order to understand the interaction between bacteria and the metals and its significance in developing biological tool to treat heavy metal wastes.
Ability of altering chemical properties of metals by microbes, with highly specific reduction and detoxification mechanisms to recognise and detoxify the target metals assures the researchers to employ microbes in clean-up of metal ions (Jonathan R. Lloyd, 2002). Which also lead in a new research opening for biotechnologists termed as bioremediation.
