Figure 2. Growth of A. hydrophila XY-16 (A), A. hydrophila NJ-1 (B) and A. media NJ-8 (C) co-cultured in the presence or absence of T. thermophila.

Bacterial growth was determined by measuring the absorbance at 450 nm (A₄₅₀) during 12 h and (T. thermophila cells had only a negligible effect on A₄₅₀). Data are expressed as the mean ± SD of four observations per time point.
