Abstract: Mutant TR-M30-1 of Klebsilla oxytoca showing 1-2 times stronger chemotaxis than its wild strain to the exudates of mycorrhiza of Eucalyptus-Pisolithus tinnctorius was screened by first using 0.1 mL/L and 0.01 μL/mL of Eucalyptus oil suspensions as the chemotaxin then the secretions of Pisolithus tinctorius, root of Eucalyptus seedings and mycorrhiza of Eucalyptus-Pisolithus tinnctorius. These results provided the initial possibility for establishing three-way mutualism system of Eucalyptus-Pisolithus tinctorius-K. oxytoca.

Key words: Eucalyptus, Klebsilla oxytoca, mycorrhiza, secretion, chemotaxis
