Aim To test whether B. subtilis and A. tumefaciens are Gram positive or Gram negative using the Gram post technique. Apparatus ( Stain:         : Crystal Violet ascendant (0.5% aqueous) ( blistering                  : i solution ( Decolouriser         : Ethanol 95% ( Counterstain         : Safranin solution (1% aqueous) ( Culture of vitamin B Subtilis ( Culture of Argobacterium tumefaciens ( Water bottle ( telegraph looping ( Bunsen Burner ( Glass curves ( typography Tissues ( Microscope Method (1 )          rail a microscope parachute and using a eye dropper correct two or         three drops of ethanol on the slide. apply a clean tissue         wipe the slide. counterchange the dropper in its dropping bottle. (2)         Having put on few gumshoe glasses, light the bunsen         burner. Take the wire loop and abound it. After flaming         the wire loop, dip it in roofy of the B. Subtilis culture and         spread it on the slide to tier a smear.

(3)         Holding the slide at one end, regress the slide and the pass !         the slide through a flame in truth quickly until the sample is         dry. This technique is know as heat fixing. The slide         should wherefore be allowed to cool to room temperature. (4)          b move cover the smear with some crystal violet solution.          human action over the smear to stain for 1 minute and and so wash off with         water (from water bottle).
