Table 1:

Classification of biofilm formation abilities by microtiter plate method

Cut-off value calculation	Mean of OD values results	Biofilm formation abilities
OD > 4×ODc	OD > 0.236	Strong
2×ODc < OD ≤4×ODc	0.118< OD ≤ 0.236	Moderate
ODc< OD ≤ 2×ODc	0.059< OD ≤ 0.118	Weak
OD ≤ 0.059	OD ≤ 0.059	None
