Abstract Hexavalent chromium [Cr (VI)] contamination is one of the main problems of
environmental protection because the Cr (VI) is a hazard to human health. The Cr (VI) form …

Chromium consists of four stable isotopes (50 Cr, 52 Cr, 53 Cr and 54 Cr) with natural
abundances of 4.35%, 83.79%, 9.50% and 2.36%, respectively (Rossman and Taylor 1998) …

from the rhizosphere of common reeds growing on the campus of the University of Waterloo …

The aerotolerant anaerobe Streptococcus pneumoniae is part of the normal nasopharyngeal
microbiota of humans and one of the most important invasive pathogens. A genomic survey …

The understanding of bacterial resistance to hexavalent chromium [Cr (VI)] are crucial for the
enhancement of Cr (VI)-polluted soil bioremediation. However, the mechanisms related to …

We have isolated a heavy metal resistance Pseudomonas sp.(designated as strain EJ01)
