Abstract


Bacteria come across a large number of stresses in their natural environments. In order to ensure their survival, highly regulated adaptive responses gets activated in bacteria which protects them from different types of stress. Thus exposure to biotic and abiotic stresses impact bacterial susceptibility to a variety of antimicrobials through their initiation of stress responses. Pro-biotic bacteria have a history of research for combating the pathogenic enterobacters. The point at the early stages behind the idea was the production of acidic environment. But was it exactly the acidic environment which denied the growth of the pathogen? This was our point of interest in present study to determine a possible way which may lead us to focus further research activities in the use of pro-biotic organism in overcoming diseases which are caused by enterobacters. Surprising results were shown from the given study. Better results are shown by lactic acid working at pH 5.5 as compared to sulphuric acid. Further acetic acid at the same pH proved midway.
