Indonesia is one of the mega diversity countries in the world endowed with rich and unique biodiversity of microorganisms, including plant growth promoting rhizo bacteria (PGPR). PGPR is considered as more sustainable, economical, and environmentally friendly alternatives to chemical fertilizers in various industries including pine plantation industries. This research aims to explore the biodiversity of PGPR in the rhizosphere of Pinus sp and Casuarina sp at Raden Soerjo Forest Park, East Java, Indonesia. Researchers successfully isolated a number of morphologically distinct microbial colonies; nitrogen fixing-, phosphate solubilizing,cellulose degrading-, and plant hormone producing- bacteria from the rhizosphere of Pinus sp and cellulose degrading, and plant hormone producing- bacteria from the rhizosphere of Casuarina sp. This research is one of the initial efforts to utilize native PGPR from Indonesia to increase the yield of farming, plantation,and other related industries in Indonesia.
