The current exploration is anticipated for isolation and characterization of diversified plant growth promoting activities of coleus rhizobacteria and augmentation of coleus plant growth. Anincongruous group of bacteria known as the plant growth promoting bacteria are found in the rhizosphere, they are seen at the root surfaces and in union with roots. Thereafter, they directly or indirectly improve the scope and quality in the growth of the plant. Though the mechanism of them whether directly or indirectly is not well understood, but its production of plant growth regulators viz., indole 3-acetic acid, gibberellic acid, indole butyric acid and their enmity against plant pathogenic microorganisms by bearing siderophores, antibiotics, phosphates and other nutrients. In this paper we reported the isolation of Stenotrophomonas maltophilia from rhizosphere of coleus forskohlii Briq. Procured from the district of Anand, Gujarat. The isolate was characterized for morphological and biochemical attributes and was identified as Stenotrophomonas maltophilia MTP42 on the basis of 16S-rRNA partial sequence analysis. The bacterial isolate MTP42 (KT428130) showed of inorganic phosphate solubilization (818ppm), Acid phosphatase activity (1.62 IU/ml), IAA production (93μg/ml), Ammonia production (80 μg/ml) and able to produce siderophore and HCN under optimized growth conditions and Trehalose, as carbon source. The following research revealed that Stenotrophomonas maltophiliaMTP42 is a propitious plant growth promoting rhizobacteria with wide array of components. Leading report of using Stenotrophomonas maltophilia MTP42 as plant growth promoting rhizobacteria from Coleus rhizosphere and use of this isolate MTP42 as Plant growth promoting rhizobacteria attempts attractive way to replace chemical fertilizers and pesticides.
