Transcriptomics extract the key chromium resistance genes of Cellulomonas
Abstract
Cellulomonas
fimi
Clb-11
can
reduce
high
toxic
Cr

to
low

In
this
study,
transcriptomics
was
used
analyze
the
key
genes,
which
involved
in
uptake
and
reduction
C.
fimi
Clb-11 .
The
results
showed
that
when
C.
fimi
Clb-11
subjected
0.5
mM
stress,
654
genes
were
upregulated.
Among
them,
phosphate
