Turbidometry
Turbidometry is
measuring
the
amount
of
light
that
passes
through
a.
suspension
of
microbe
with
a
spectrophotometer
or
other
optical
measuring
device
is
also
used
for
estimation
of
cell
mass,
since
the
amount
of
light
absorbed
or
scattered
by
the
microscope
is
proportional
to
its
cell
density.
Spectrophotometer
measures
absorbancy
units
(A),
defined
as
follows:
A
=
log(l0/l),
where
I0
is
the
intensity
of
light
striking
a
suspension
and
I,
the
intensity
of
light
transmitted
by
the
suspension.
