Table 2 Efficiency of lysogenisation by phage λ cI857 S7 of E. coli cells cultivated in different media

Medium	Efficiency of lysogenisation^a
	m.o.i. = 1	m.o.i. = 10
LB	0.44	0.72
M9GluCaa	0.06	0.14
M9Glu	0.02	0.14
M9Gly	0.82	0.96

^a An efficiency of lysogenisation of 1 would represent 100% lysogens among survivors and presented values reflect this value. The results are average values from three experiments. In all cases, the standard deviation was below 10%
