Because of their huge biodiversity and metabolic capabilities, the
application of microorganisms as bioremediation agents is a way to enhance
pollutant degradation. The aim of this research was to investigate the
potential of five strains of Pseudomonas sp. as possible bioremediation
agents. Strains are from the Collection of the Microbiology Department,
Faculty of Agriculture, Novi Sad. Bacterial strains were cultivated in King?s
B liquid medium and incubated in shak?er at 28?C. Starter culture was
obtained after 24h, CFU 108. This 24h old bacterial culture was used for the
analysis of influence of five different natural naphthenic acids. Bacterial
growth was determined spectrophotometrically through optical density, after
24h and 48h of growth. Our results showed that two bacterial strains (PS V1
and PS2) had better growth after 48h as they used C from the petroleum
derivates. The growth of these strains was increased by 72% and 25% with
deri?vates concentration of 10-5 mol/cm3 and 10-6 mol/cm3, respectively. The
results of this research showed the potential of certain bacterial strains as
bioremediators.
