For endorhizospheric sample the roots were surface sterilized with 70% ethanol and washed 2 to 3
times to remove excess disinfectant. Root material was
suspended in phosphate buffer and crushed with sterial scalpel.
The leaves and stem were washed with sterile distilled water
and their surface disinfected by washing with 70% ethanol. 10 g
of stems and leaves were macerated separately in sterile 10 mM
Tris-HCL, pH 8. All these suspension were serially diluted up to
10-8. One hundred micro liters of appropriate dilutions was taken
and performed spread plate on different media viz. king’s B
medium (KBM), ashby’s mannitol agar (AMA), nitrogen free
medium(NFM), yeast extract mannitol agar (YMA),
azospirillum medium (AZ), pikovskaya medium (PM), bacillus
medium(BM). The plates prepared were incubated in room
temperature for 48 h. Bacterial cultures were maintained on the
respective slants and stored at 4°C for further use.
