Decimal reduction times (D values) for WT and Nis^r C. botulinum 169B spores at three different temperatures in the presence or absence of 10³ IU of nisin per ml^a

Strain and condition	D value (min) at temp (°C) of:
	80	100	110
WT control	883.7 ± 43.9	27.2 ± 7.9	1.4 ± 0.01
WT + nisin	577.0 ± 95.7b	16.5 ± 3.6b	0.8 ± 0.04b

Nisr + nisin	871.2 ± 53.6	22.9 ± 3.5	1.4 ± 0.06

^aResults represent the mean ± SD for three independent experiments. 

^bSignificantly different from values obtained with the other strains and conditions.
