Abstract

An on-line glucose flow injection analysis system was developed and used for the automatic analysis and addition of glucose in the cultivationof a Saccharomyces cerevisiae in a korean paper digestion wastewater in order to increase the cell concentration. The system was composed of a ceramic sampler a sampling valve an injection valve an immobilized glucose oxidase column a debbble a flow cell with platinum electrodes a potentiostat a computer and interface system and tubing pumps. The glucose concentration of the wastewater medium was mainitained at the low concentration of $176{\pm}31 mg/L$ with the on-line FIA system and by adding glucose and $>(NH_4)_2S0_4$ the cell concentration as total cell count can be increased by 3.1times.

한지자숙폐액을 이용한 Saccharomyces cerevisiae의 배양에 서 glucose의 자동분석 및 첨가에 의해 균농도를 증가시킴으로써 폐액의 재이용성을 향상시키파 하였다 배양액의 glucose를 자동분석하고 자동첨가하기 위하여 ceramic sampler, sampling, ralve, injection valve, glucose oxidase column, debubbler, flow cell과 백금전극, potentiostat, computer와 interface card, 및 tubing pump블로 구성된 glucose 자동분석 및 첨가시스템을 제작하였으며, glucose의 자동분석에는 glucose oxidase를 이용한 on-line FIA법을 채택하였다. 효모의 배양중 glucose자 동분석 및 첨가시스템을 사용하여 glucose를 자동첨가한 결과 배양액의 포도당농도가 $176{\pm}31 mg/L$ 의 낮은 농도로 제어 되었으며, glucose와 $>(NH_4)_2S0_4$의 첨가에 의해 총균수가 3.1 배 증가하였다.
