Positive:
The decrease in bacterial colonization will prevent the plant from the diseases caused by the bacteria and this will promote plant growth. Like, black rot in Brassica caused by Xanthomonas campestris, bacterial canker in tomato, capsicum and chilli caused by Clavibacter michiganesis.
Negative:
Plants remains in symbiotic relationship with bacteria in order to obtain impermeable inorganic minerals from the soil. In the absence of bacteria, the plants will not receive these nutrients, and their growth may be hampered. Example bacteria fixes atmospheric nitrogen which is taken up by the root nodules of leguminous plants. In return these bacteria gets the food like carbohydrates produce by the plants.
