Environmental
Factors
Afftecting
Microbial
Growth.
It
can
be
seen
that
this
growth
is
very
rapid
and
the
high
growth
rates
require
suitable
control
of
nutrients
and
physical
and
chemical
conditions
of
the
environ
ment.
The
physico
chemical
factors
of
natural
environment
determine
the
rates
of
microbial
growth
and
the
nature
and
size
of
the
indigenous
population.
1.
Temperature.
Environmental
temperature
is
one
of
the
most
important
factors
affecting
the
growth
rate
of
microbes.
There
is
a
minimum
temperature,
below
which
growth
does
not
occur.
