Alleviation of osmotic stress by exogenous sucrose in S. meliloti 102F34

Osmotic agent addeda	Growth parameter in LAS medium containingb:
	No addition		0.5 mM sucrose
	μ	ODmax	μ	ODmax
None	0.200	1.9	0.200	1.9
0.5 M NaCl	0.051	0.9	0.120	1.9
0.5 M KCl	0.042	0.8	0.105	1.7
0.45 M K2SO4	0.020	0.4	0.060	1.2
0.8 M mannitol	0.060	1.1	0.100	1.8
0.8 M glycerol	0.250	2.1	0.250	2.1

^aEach was added to LAS medium at a concentration which developed the same osmotic pressure as 0.5 M NaCl.
