Abstract :Abstract
Microbial enhanced oil recovery is an ecofriendly approach used to enhance the recovery of oil.
In this investigation, formation water was collected from the oil wells of Gujarat. The formation
water was enriched with the desired nutrients, to facilitate the growth of indigenous microbial
species under reservoir conditions. The microbial species (TERIK) were morphologically analyzed
through scanning electron microscopy. The acute oral toxicity of the microbial species was screened.
Microbial species were appeared to be non-virulent and non-pathogenic. Hence, these species were
appeared to be safe for field implementation.
