| Summary: | Interaction of microbes with human living in the nature are able to seen from their capabilities
improving the environmental by composting waste of agriculture to become organic fertilizer. In the
contrary, the epidemic and infectious phatogens are also its contribution. In agriculture sector, the living
of microbes has been explored to keep the soil fertile, and to improve growth and plant production.
The symbiosis of Rhizobium bacteria with the specific host plant from legumes is able to run because of
both side giving a signal, where host plant give an organic molecoles called inducer. From the bacteria
side, also give an organic materials called nod factor. The step of nitrogen fixation mechanism can be
described from infection of root legume as the first step, followed by the nitrogen fixation by the
bacteroid and synthesis of the nitrogen organic by host plant as the last step. These natural processes
inspire finding and development of the ecologically organic fertilizer technology.
