MICROORGANISM :FRIEND AND FOE
Throw lights on the long standing
debate of whether microorganisms
Are good or bad. Thus, this chapter
will help,
to an extent, in clearing this matter.
You can
easily learn about various forms of
microorganisms
and their shapes and sizes. Other than
that, you will
learn about where they live as well.
Furthermore, it
discusses the various uses of
microorganisms in commercial and
medicinal sectors.
After that, it also covers the subject of harmful microorganisms
and tells about them in detail. You will also learn about the various
techniques of food preservation and the role of microorganisms in it. In addition, the
student will be made familiar with Nitrogen fixation
and the Nitrogen cycle in a brief manner. Thus, it assists the students
in getting a fair idea about the advantages and disadvantages of microorganism.
INTRODUCTION OF MICROORGANISM
M any microorganisms are present in soil, water and air around us. Some of these
organisms are so small that we cannot see with our naked eyes. We need a magnifying
instrument called microscope to see these extremely small organisms
, (micro=extremely small). We can now say: Those microorganisms that we cannot see
with our naked eyes are known as microorganisms or microbes .
MAJOR GROUPS OF MICROORGANISM
Microorganism are classified into four major groups
1.BACTERIA
2.FUNGI
3.PROTOZOA
4.ALGAE
BACTERIA
Bacteria are tiny, single-celled living organisms. There are millions of different types of
bacteria. Many can be found in and on your body and are beneficial to you. These
bacteria make up your microbiome, which keeps your body healthy. Other bacteria can
make you sick.
TYPES OF
BACTERIA
1. ROD SHAPED
2.SPIRAL SHAPED
3.SPHERE SHAPED
FUNGI
Fungi are eukaryotic microorganisms.Fungi can occur as yeasts, molds, or as a
combination of both forms.
