A matrix method has been developed for calculating dissolved oxygen profiles near and within slimes of microorganisms bathed by flowing nutrient medium. The matrix manipulations and recursions necessitated by non-linearities in the equations are carried out in FORTRAN programming on an IBM-360 computer. The computer provides numerical output and plots of dissolved oxygen concentration versus either distance from the slime surface or distance along the slime. A diffusion mechanism is assumed, and equations are derived from mass balances for oxygen and from the laws of diffusion. Two situations which were studied in detail were the development of steady-state oxygen profiles as medium flowed past a microbial slime and the profile established at an infinite distance along a microbial slime.
