C/N ratios of the PSI-less control and the PSI-less/ScpABCDE⁻ mutant in the presence or absence of NaCl calculated after ATR FT-IR

	C/N
PSI-less	0.63 (± 0.12)
PSI-less+NaCl	0.44* (± 0.1)
PSI-less/ScpABCDE−	1.38*** (± 0.06)
PSI-less/ScpABCDE−+NaCl	0.75*** (± 0.05)

Standard deviations with n ≥ 3 are given in brackets

P values are classified as: *0.01 to 0.05 significant; **0.001 to 0.01 very significant; ***< 0.001 extremely significant
