Abstract
A cell culturing system includes an enzyme sensor that detects a concentration of a predetermined component of a culture medium used for culturing of cells, a sensor flow path in which the enzyme sensor is disposed, and a bioreactor that performs culturing of cells while causing the culture medium to flow through the sensor flow path, and further includes a deterioration index calculation unit that determines a deterioration index of the enzyme sensor, based on a detected concentration value of the enzyme sensor, and a detection period during which the detected concentration value is detected, and a lifespan determination unit that detects whether or not an integrated value of the deterioration index has reached a threshold value, and thereby determines the lifespan of the enzyme sensor.
