Isolation and characterization of bacteria and yeasts from contaminated soil
Plant growth promoting (PGP) bacteria and yeasts play an important role in bioremediation processes. Thirty bacterial and ten yeast isolates were obtained from PAH and PCB contaminated soil with an aim of determining the presence of PGP mechanisms (production of ammonia, indoleacetic acid,...

| description | Plant growth promoting (PGP) bacteria and yeasts play an important role in
bioremediation processes. Thirty bacterial and ten yeast isolates were
obtained from PAH and PCB contaminated soil with an aim of determining the
presence of PGP mechanisms (production of ammonia, indoleacetic acid,
siderophores and solubilization of inorganic phosphate). As a result, three
bacterial (Serratia liquefaciens, Micrococcus sp. and Serratia sp.) and two
yeast isolates (Candida utilis and Candida tropicalis) were recognized as PGP
strains. Among them, Serratia sp. showed the highest indole production (25.5
μg/ml). Analyses of metal tolerance (Cu+2, Cr+6 and Ni+2) revealed that
Serratia liquefaciens, Micrococcus sp., Serratia sp. and Candida tropicalis
were capable to tolerate significant concentration of metals. As a result of
this study several bacterial and yeast strains were attributed as potential
plant growth promoters which can be applied in future remediation activities
and environmental quality improvements. [Projekat ministarstva nauke
