Abstract
The survival of Salmonella typhimurium was investigated by bioluminesc ence and standard plating techniques in pure cultures and in the prese nce of competitors after the cultures were heated to 55 degrees C for increasing lengths of time. Decimal reduction (D) values increased fro m 0.43 to 2.09 min in the presence of 10(8) CFU of competitors ml(-1), indicating a significant protective effect.
