Method 
P.5529 left column: "The metabolic capabilities of the in silico metabolic
genotype were partially defined by mass balance constraints mathematically represented by a matrix equation:
S•v=0. The matrix S is the m×n stoichiometric matrix, where m is the
number of metabolites and n is the number of reactions in the network. The E. coli stoichiometric matrix was 436×720."
