Title: Timothy J. Herdendorf and Real-Time Bacterial Spore Detection

Introduction

Timothy J. Herdendorf is an inventor associated with Sullivan, Wisconsin, and the University of California. His patent work addresses the detection of viable bacterial spores, which can help distinguish living spores from those that are no longer viable.

Latest Patents

Herdendorf is named on 1 patent: “Real Time Viability Detection of Bacterial Spores.” The invention describes a process that places a sample in a germination medium long enough for viable spores to begin germination, then combines the sample with a lanthanide solution that forms a fluorescent complex with dipicolinic acid. Measuring for dipicolinic acid provides an indication of viable spores in the sample.

The patent also describes a detection system with a germination chamber, sample and reagent inlets, a filtering outlet, and a detection chamber. A fluorescence-promoting metal is introduced into the detection chamber, where an excitation source and emission-spectrum measurement are used to detect the sample. The system also includes a waste chamber. The invention further identifies a germination mixture containing L-alanine, L-asparagine, and D-glucose to promote commitment to germination by viable spores.
