Tabular Form of Bacterial Classification From David Bergey's Manual
This
group
consists
of
Gram
negative
bacteria
in
which
products
of
binary
fission
are
not
equal
although
reproduction
is
either
by
budding
or
by
binary
fission.
Some
have
excreted
appendages
and
hold
fasts.
Budding
occurs
by
the
formation
of
small
tube
like
outgrowth
(prostheca)
on
the
surface
of
the
mothercell.
The
tip
of
the
tube
like
structure
grows
until
it
attains
a
volume
similar
to
that
of
mother
cell
and
then
becomes
detached
from
it
.
In
some,
where
cell
division
occurs
by,
binary
fission,
(as
in
Caulobacter)
two
dissimilar
daughter
cells
are
formed.
Important
genera
include
Hyphomicrobillm.
Caulobacter
and
Gallionella.
Majority
are
chemoheterotrophic.
