Proposal for a method to estimate nutrient shock effects in bacteria

BMC Research Notes

Table 2 Nutrient shock index obtained for the four species used in this study

Bacterium	A.I. in water	P value for water	A.I. in TSB	P value for medium	Nutrient shock index
S. capsulata	147^a	<0.001	38	0.065	109
E. coli CECT 434	6.25	<0.001	−1.62	1.000	7.87
Methylobacterium sp.	8.71	<0.001	−1.09	1.000	9.78
P. fluorescens ATCC 13525	−0.47	1.000	−6.30	<0.001	5.83

^aFor the two time points where readings of CFU for TSA were 0, logCFU was considered to be 1.
