Isolation and characterization of plant growth promoting potential of Acinetobacter sp. RSC7 isolated from Saccharum officinarum cultivar Co 671
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Genus Acinetobacter can be exploiting as an ecofriendly plant-growth promoting rhizobacteria and as an alternative to chemical fertilizers. In present study, Acinetobacter strain RSC7 isolated from the rhizosphere of sugarcane cultivar Co671 has been used for the characterization of plant growth potential and molecular identification through 16S rRNA gene sequence. The phosphate solubilisation Index (SI) of the isolate strain was tested on the Pikovskaya agar and recorded 3.5 and quantitative estimation of isolated strain revealed that maximum 27.10μg/ml phosphate was releases in NBRIP broth with 1.5% tricalcium phosphate after 120 hr incubation at 37°C. Further, IAA production was also estimated and it was reported 20.89μg/ml after 24 hr and within 48 hr production significantly increase to 43.85μg/ml. Acinetobacter strain has potential to act as plant-growth promoting rhizobacteria and can enhance the growth of Vigna radiate, Vigna unguiculata, Abelmoschus esculentus, Dolichos lablab. The improved seedling growth parameters of the treated crop seeds indicated the potential of Acinetobacter sp. RSC7 to be used in a bio-fertilizer formulation for sustainable production.
