These bacteria
were isolated from corn roots samples by Ikeda et al.
(2013). For the isolation, corn roots from field trial
conducted at Semilia Genetics and Breeding LTDA,
located in the southern Brazilian region of Campo Largo-
PR, were surface-sterilized (Petrini, 1986) and aseptically
cut, then transferred to Petri dish plates containing
solid culture media. Several controls confirmed that the
sterilization procedure was effective.
