Chemical engineering

Microorganisms that exist in the nature of this has morphology, structure and
distinctive traits, as well as bacteria. Bacteria that live almost no
color and contrast it with water, in which bacterial cells are suspended.
One way to observe the shape of bacterial cells making it easy to
is identified with a method of painting or staining. It also
to know the nature of the physiological function that describes the reaction of the cell wall
bacteria through a series of painting (Dwidjoseputro, 1994).
The purpose of staining is to make it easier to see bacteria
with a microscope, to clarify the size and shape of bacteria, to see
outer structure and the structure of the bacterial cell wall and vacuole, such as,
produce the physical properties and chemical properties than the typical bacterial substances
color, and increase the contrast with surrounding microorganisms (Pelczar &
Chan, 1986).
Color staining technique for bacteria can be divided into three
kinds of simple painting, painting and staining differential
structural. Giving color to the bodies of bacteria or other microorganisms
using a single solution of a dye on a thin layer, or spreads, which
been fixed, called the simple stain (Pelczar & Chan, 1986).
Staining procedures that show the differences between cells or Microbe
Microbe cell parts called differential staining technique (Pelczar & Chan,
1986). . While the painting of structural coloring only one part of the cell
so that it can distinguish the parts of cells. Included in the painting
This is a painting endospore, flagella and capsule staining.
