Electronic computer solution for the MPN equation used in the determination of bacterial populations

The utility and the practical precision of the Most Probable Number method for determining bacterial populations is currently restricted by a lack of adequate tables of solved examples or alternatively by an easy and quick solution to individual problems. Where an electronic computer is available, these restrictions need not apply. A computer programme and example solution for tabulated data and individual problems are presented in this paper.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38438/1/390020205_ftp.pd

Combined irradiation–heat processing of canned foods: Green peas inoculated with anaerobic bacterial spores

Combined irradiation–heat processing is shown to be syner-gistic for killing anaerobic bacterial spores inoculated into canned green peas. Following 1·2 megarad of gamma irradiation an F 0 of 0·5 sterilized green peas inoculated with either 5,000,000 Clostridium botulinum 213 B or 300 PA 3679 spores per can. This processing schedule must be considered a minimum since it is based on a limited number of cans. Because sterilization by either irradiation or heat alone can damage the organoleptic properties of canned foods, the lowered schedules possible with combined processing may prove to be of value for preserving vegetables as well as meats.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38436/1/390020102_ftp.pd
