Experimental determinations were made with a specific aerobic microbial species and it was concluded that the cells can convert 2/3 of the glucose carbon present in the medium into biomass.

Knowing NH 3 is the source of nitrogen and that the elemental formula of biomass is C_4,4 H_7,3 O_1,2 N_0,86,

calculate:

a - Stoichiometric coefficients of the microchemical equation

b - Y xs (kg dry weight / kg glucose) and Y xo (kg dry weight / kg oxygen)
