AB  - The Cr (VI) reducing capacity of bacteria has been investigated in many different soils and waters but little or no information is available from soils originating from bauxite mine areas. From soil, mud and rhizospheres of the floating aquatic plant Potamogeton natans L. and the terrestrial plant Carduus acanthoides L., the Cr content was determined and the microbial populations were sampled. The highest total chromium concentration (204.6 mgkg(-1)) was found in the rhizosphere of C. acanthoides. To determine the numbers and percentages of chromate-resistant bacteria, the autochthonous microbial populations were subjected to different Cr (VI) concentrations (40, 100, 300 and 1000 mM as K2Cr2O7). At 1000 mM Cr (VI) in the medium, about 25% of bacteria from soil and 45% of bacteria from the rhizospheres were resistant. Of 34 bacterial isolates, within 24 h, only Bacillus stearothermophilus 12 ms, Pseudomonas sp. 12 bk3 and Serratia fonticola 7 be were able to reduce 50 mu M Cr (VI). Using prolonged 72 h incubation, they were able to reduce 500 mu M Cr (VI) concentrations added to the medium. These chromate-resistant bacteria isolated from rhizosphere of plants growing in bauxite mine soil have great potential for bioremediation of Cr (VI)-polluted wastes.

AB  - Mine exploitation often produce heavy divested soils without any vegetation and biological potential. However, the most mine soils contents heavy metals too. In this study first we were investigate the metal contents in soil, water and plants samples taken from bauxite mine in Milici (B&H) at two locations. Results showed that total contents of Ni (50.4 - 99.2) and Cr (10.6-209.6 mg/kg) in the soil samples exceeded their maximum allowed for unpolluted soils. Such divested lands could be biological active only if the different microorganisms are present in a soil as a first step in recultivation. Due its, dominantly systematic group of microorganisms were determined. Results showed that bacterial populations were highest in the rhizosphere (21.6 x 105 - 91 x 105). Lower content of bacterial populations were found in the water samples (5.3 x104 - 14 x 104). Activity of the enzyme dehydrogenize (as soil healthy indicator) was highest in the mud samples (33.62 μgTPF/l0gr).
AB  - Eksploatacijom uglja se često dobijaju jako osiromašena zemljišta bez vegetacije i biološkog potencijala. Pored toga, većina ovih zemljišta sadrži i teške metale. U ovom istraživanju je prvenstveno analiziran sadržaj metala u uzorcima zemljišta, vode i biljaka koji su uzeti sa dve lokacije iz okoline rudnika boksita u Milićima (BiH). Rezultati analize su pokazali da je ukupan sadržaj Ni (50.4-99.2) i Cr (10.6-209.6 mg/kg) u uzorcima zemljišta prelazio maksimalne dozvoljene količine za nezagađena zemljišta. Ovako osiromašena zemljišta mogu biti biološki aktivna samo u slučaju da su u njima prisutni drugačiji mikroorganizmi, što predstavlja prvi korak u rekultivaciji ovih zemljišta. Zbog toga su određene dominantne sistematske grupe mikroorganizama. Rezultati su pokazali da su bakterijske populacije bile najbrojnije u rizosferi (21.6xl05-91xl05). Niže koncentracije bakterijskih populacija su nađene u uzorcima vode (5.3x10 -14x10 ). Najveća dehidrogenazna aktivnost (kao indikatora zdravstvenog stanja zemljišta) je bila u uzorcima mulja (33.62 μgTPF/l0gr).
