ABSTRACT
Bacteria play an important role in maintaining the health status of soil ecosystem by preforming many
biological processes. Among PGPR were Azotobacter sp and Pseudomonas sp are considered as an
important genus which is closely-associated with plants and shows potential to improve the plant health
and increase maize yield. Azotobacter sp and Pseudomonas sp was isolated from the maize rhizosphere
from Jatinangor, District Sumedang, Indonesia. The present study was carried out for the isolation of
Azotobacter sp and Pseudomonas sp which can be used as crop inoculants. Azotobacter sp and
Pseudomonas sp was purified and subcultured in their respective medium. The result showed that were
two isolates of Azotobacter sp and two isolates of Pseudomonas sp.
