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

From: Proposal for a method to estimate nutrient shock effects in bacteria

Bacterium A.I. in water P value for water A.I. in TSB P value for medium Nutrient shock index
S. capsulata 147a <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
