METHOD FOR PROVISIONALLY DETERMINING QUALITY OF BALLAST WATER, METHOD FOR TREATING BALLAST WATER, METHOD FOR PROVISIONALLY DETERMINING COMPOSITION OF ORGANISMS, METHOD FOR EVALUATING BIOLOGICAL ACTIVITY, AND METHOD FOR PREDICTING CONCENTRATION OF ORGANISMS

摘要

The purpose of the present invention is to provide: a method for provisionally determining the quality of ballast water, which comprises provisionally determining whether or not the composition of organism in the ballast water meets a standard; a method for treating ballast water, which comprises treating the ballast water on the basis of the determination method; a method for provisionally determining the composition of organisms, which comprises provisionally determining whether or not the composition of organisms in a sample of interest meets a standard; a method for evaluating a biological activity, which comprises directly and rapidly evaluating organisms occurring in a culture medium of interest as an activity; and a method for predicting the concentration of organisms, which comprises rapidly predicting the concentration of organisms occurring in the culture medium. The purpose can be achieved by evaluating organisms occurring in a culture medium of interest as an activity or predicting the concentration of organisms occurring in the culture medium on the basis of the amount of a substrate consumed in accordance with the progress of culturing in the culture medium.
