A method of monitoring cell culture which comprises digitizing an image of cultured cells inputted to an image processing equipment through a TV camera connected with an observing means and measuring the number and cell proliferation of cultured cells by a processing with using a spatial filter, can treat a large amount of cells in a short time and give a precise number of the cells.

Method of monitoring cell culture

A method of detecting undesired microorganisms when cells are cultured in a light permeable container is disclosed. TV camera monitors the image of a well containing microorganisms through a microscope. The output of the TV camera is processed by a picture digital processor so as to count the number of cultured living cells. On the other hand, change of the light absorption of the visible light by the cultured solution is measured. Then the number of undesired microorganisms can be calculated by the number of the living cells and change of the light absorption.
