* M. testaceum B2 induced growth alteration in rice seedlings treated with 10⁸ and 10⁷ CFU mL⁻¹, bacterial suspension after seven days. (The data with the same alphabet in each column were significantly similar to each other, but the data with different alphabets were significantly different. The letter ns stands for non-significant.).
