Comparison of data calculated for M. fortuitum grown in Middlebrook 7H9 with E. coli B/r grown in succinate medium.

, data for E. coli B/r [20]. The value for n RNAP(rrs) was calculated using equations (1) and (2): n R(i)(av) and n R(j)(av) were calculated using equations (8) and (9); n tr(i)(av) and n tr(j)(av) were derived from n R(i)(av) and n R(j)(av) by means of n R(i)/tr(i) and n R(j)/tr(j). The value of ε aa(av) was assigned to ε aa(i) as reported for rpsA [23].
