Abstract
In this study, 21 environmental bacterial isolates isolated from different environmental sources in Basra Governorate identified phenotypically and genetically based on 16 rRNA gene sequence analysis were screened to reveal their ability to produce biopolymer based on the viscosity scale formed in the cultural media and use of Sudan Black stain. Six isolates showed their ability to produce biopolymer, and the two isolates of Bacillus licheniformis strain CC91, Bacillus thuringiensis strain LU3 recorded the best results. The isolate of the Bacillus licheniformis strain CC91 was tested in the process of sealing fractures and openings with high permeability for samples of oil reservoir rocks.
