Even formerly the
discovery of the life of microorganisms, human being produced fermented foods.
Also degrading activity of microorganisms has been used in human waste, which
is naturally biodegradable.
However, for
large-scale treatment, human being had to devise artificial processes of competition
degrading activity of naturally occurring microorganisms.
Microbiologists,
engineers and chemists have worked hand in hand in this regard, now we know
that for biodegradable materials, other than human waste, the process is also
true. These biological systems for waste management belong to one of the
largest area for biotechnological applications.
