Correction

  1. 1.

    On page 4 of the original publication [1], the correct sentence should read:

    Quantitative measurement was performed by dissolving CV stained pellicle in 4 ml of 85% ethanol and the OD570 was measured using microplate reader at 200 μl per well.

     
  2. 2.

    Table 2 of this original publication contained some errors. The updated Table 2 is published in this correction article.

aValues are shown as mean of biofilm production ± standard error on polystyrene surfaces, SS: stainless steel, GS: glass slide at 25 °C. According to the biofilm

mass quantified with crystal violet staining assay at 570 nm isolates were labelled as the following: low, medium and thick biofilm formers

bVisible biofilms on stainless steel and glass slides and was scored as 0: no visible biofilm, scored on a scale from 1 to 3 to a thick biofilm at the air-liquid

cThe presence and absence of visible pellicles biofilms was scored visually before staining with CV. Strains with visible pellicles at the air-liquid interface had OD570 ≥0.48
