Viable cell counts without (grey) and with (black) treatment with SaBeH (100 M) over 60 min given in percentage. Negative values denote total counts of dead bacterial cells obtained by subtracting counts of viable bacteria grown without SaBeH (100%) from counts of viable bacteria grown with SaBeH. Data are presented as the percentage of the total counts of dead bacteria with standard deviations for three independent biological replicates ( n = 3): SaBeH treated E. coli (-40 19) and S. aureus (-87 43).
