Growth-Promoting Potential of Rhizobacteria Isolated From Sugarcane

The search for plant growth-promoting rhizobacteria (PGPRs) addresses the ongoing need new bioinoculants to be used on various agricultural crop species, including sugarcane. Bacterial strains were isolated from rhizosphere of sugarcane plants and identified by sequencing 16S ribosomal gene. main indole acetic acid producers Enterobacter sp. IP11, IP14, E. asburiae IP24. Achromobacter spanius IP23 presented highest levels cellulolytic activity potassium solubilization. Bacillus thuringiensis IP21 Staphylococcus saprophyticus IJ8 showed fixed nitrogen. calcium phosphate aluminum in B. notable, as this strain solubilized 481.00 39.33 mg phosphorus mL −1 , respectively; however, Araxá apatite, results anthracis IP17 notable (622.99 ), while iron solubilization, which 105.66 was notable. IP11 isolates promoted growth tallest plants, inducing increases 14.1 10.4% relative control respectively. For shoot dry matter, root total inoculated with IP17, A. higher values than controls. Furthermore, matter values, those IP14 also values. These indicate that bacteria potential use future inoculants should investigated since growth-related characteristics may not impact promotion.
