What makes a heavy metal resistant bacterium heavy metal resistant? The mechanisms of
action, physiological functions, and distribution of metal-exporting proteins are outlined …

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 …

We present an analysis of over 1,100 of the∼ 10,000 predicted proteins encoded by the
genome sequence of the filamentous fungus Neurospora crassa. Seven major areas of …

Chromium is a non-essential and well-known toxic metal for microorganisms and plants. The
widespread industrial use of this heavy metal has caused it to be considered as a serious …

An Gram negative strain of S. maltophilia, indigenous to environments contaminated by Cr
(VI) and identified by biochemical methods and 16S rRNA gene analysis, reduced chromate …

Abstract Background Some Pseudomonas strains function as predominant plant growth-
promoting rhizobacteria (PGPR). Within this group, Pseudomonas chlororaphis and …

Sulfur is an essential element for microorganisms and it can be obtained from varied
compounds, sulfate being the preferred source. The first step for sulfate assimilation, sulfate …

The plant growth-promoting bacterium (PGPB) Pseudomonas sp. UW4, previously isolated
from the rhizosphere of common reeds growing on the campus of the University of Waterloo …

Two bioflocculant producing bacterial isolates from mining soil samples were investigated
for their application in heavy metal removal. The bacterial isolates were identified as …

Chromium pollution is increasing incessantly due to continuing industrialization. Of various
oxidation states, Cr 6+ is very toxic due to its carcinogenic and mutagenic nature. It also has …
