Abstract

A dynamic programing method was applied for maximizing a production yield in controlling the process of aerobic bacteria fermentation. An optimal control was carried out by air flow rate under a sufficient sugar supply condition, using the bacteria amount as a state variable and the air flow rate as an operation variable, under conditions where the sugar consuming rate is not a limiting factor. The growth and production were modelled, and the relationship of both the specific growth rate and the specific production rate to the specific respiration rate was was expressed as functional tables. A simulation was carried out, which provided an optimum air flow pattern. This relationship between the bacteria amount and the optimum air flow rate was mapped to perform a map control. Conditions other than the air flow pattern were made to agree with the previous empirical cultivation method, and experiments were conducted using a cultivation tank of 0.03 m {sup 3}. A yield increase of 13.6% over the conventional method was attained, thus the reasonability of the modelling was verified. It was found that there are portions where the width of the optimum air flow control is wide and narrow, and it is possible to  More>>
