Abstract EN
The biotransformation of hexavalent chromium [Cr(VI)] via Cr(VI)-reducing microorganisms is considered an ecofriendly approach to detoxify Cr(VI).
A new Cr(VI)-reducing bacterium named Microbacterium sp.
QH-2 was isolated in this study.
Scanning electron microscopy (SEM) images showed protrusions on the bacterial surface of strain QH-2 after an 18 h incubation in media under 10 mM Cr(VI) treatment.
Results of the experiments on the capacity of reducing Cr(VI) indicated that strain QH-2 could reduce 100% Cr(VI) less than 48-96 h.
When media with 4 mM Cr(VI) were incubated, the fastest reduction rate of strain QH-2 could come up to 2.17 mg/L Cr(VI) h−1.
Furthermore, strain QH-2 could reduce Cr(VI) over the pH between 7 and 10.
The optimum pH to reduce Cr(VI) by strain QH-2 was 9.
Strain QH-2 also exhibited a relatively high tolerance even to 20 mM Cr(VI).
These results declared that strain QH-2 had the potential to detoxify Cr(VI) in the Cr(VI)-contaminated soil or effluent.
