IDENTIFIKASI BAKTERI TANAH DI KEBUN BOTANI BIOLOGI FKIP UNIVERSITAS JAMBI
Abstract: Soil bacteria has
important role in the life cycle of an ecosystem. Their life activities affect
the characteristics of the biologic, physical, and chemical environment.
Biology study program of education faculty in Jambi University has a plot of
land made into a botanical garden. Thus, this botanical garden needs some
information about the fertility of the land used, and one of them is to know
the type of bacteria in its soil as a biological factor. The purpose of this
research is to determine the genus of bacteria found in soil of Biology
Botanical Garden at Education Faculty (FKIP) of Jambi University, Mendalo. This
research was conducted from April to July of 2015, in both biology botanical
garden and biology laboratory at Education Faculty of Jambi University. The
kind of this research is explorative descriptive. Soil sample was collected by
using 4 squared plots measuring 12 m x 12 m. In each plot made 5 subplots and
soil samples was taken from 3 points of each subplot by random sampling. The
identification was done by observing colony morphology, gram staining, and
biochemical tests. The result of this research was gained gained 9 genus of
bacteria, they were Paracoccus, Nitrosococcus, Bacillus, Cellulomonas,
Acinetobacter, Micrococcus, Pseudomonas, Azotobacter, and Zymomonas. It is
suggested to further researchers to study about other microorganisms in the
soil Biology Botanical Garden that have role in maintaining and improving soil
fertility there.
