Sulfate reducing bacteria (SRB), which have relatively simple
growth requirements in sulfate and carbon as energy sources,
play a very negative role in MEOR [19,46]. Also it is well
known that the cationic surfactants were commonly used to
control the SRB growth [47,48]. Table 6 shows the effect of
different concentrations of crude biosurfactant produced by
B. licheniformis as antimicrobial activity on the growth of sulfate reducing bacteria (SRB). Biosurfactants can graduall
