发明名称 Method for constructing a diversity index and a viability index of microorganisms in process samples
摘要 The invention is directed towards methods and compositions for identifying the specific microorganisms present in a particular portion of a papermaking processes. The method involves obtaining and comparing a diversity index of a sample from the process. Because no system is completely free from biological infestation, utilizing information taken from the changes in the populations provides information useful in protecting the system from unwanted effects. Not only does the diversity index allow for the distinguishing between biological and non-biological events, it even allows for the prediction of problems without previously knowing that a particular organism will cause a particular problem.

主权项 1. A method of addressing a microorganism infestation in an industrial process system, the method comprising the steps of: taking at least one first measurement which identifies the relative concentration of two or more organisms present in at least one portion of the industrial process system, taking at least one second measurement which identifies the relative concentration of two or more organisms present in the at least one portion of the industrial process system, the identifications at least partially defining a subsequent diversity index, the at least one second measurement taken later than the first measurement(s), noting any relative change in concentration of the two organisms, if the relative concentration of one of the measured organisms exceeds a pre-determined threshold amount, determining if the change is associated with an unwanted effect on the industrial process system, and implementing a remedy to remediate the unwanted effect wherein regardless of the identity of the at least one organisms, if their relative concentrations increase relative to the prior measurement by an amount more than the threshold even if the overall biological population remains the same, a biocide treatment is added to the system.
