Different bacteria have different metabolism and their rate also
differ .
- Bacteria role in ecosystem : microbes provide nutrition to the
plants by decomposing the organic matter present in the soil . If
we know the bacterial metabolism then we can increase the rate of
decomposition of the organic matter in the soil and increase the
plant growth and development.
- Bacteria role in immune system : all bacterial strains are not
infectious some are beneficial also. If we know the metabolism of
the disease causing bacteria then it is easy to develop the vaccine
against that pathogen or bacteria without affecting other
beneficial microbes.
- Phylogenetic analysis: To establish a relationship among or
between the organism it is important to exhibit similarities
between them. If we are aware of bacterial metabolism we can
identify the other bacterial species which are closely related to
that bacteria.
