A dry starter of
Tetragenococcus halophila was developed by fluidized-bed drying. Protective reagents from dehydration, cell supporting substances in fluidized-bed drying, and various conditions of the drying were investigated. Among the protective reagents tested, the highest cell viability wasderived from 20%(w/v) sucrose. Skim milk was adequate as a cell supporting substance. Good results were obtained at 8 m/
lmin for a flow rate of cell suspension and 11 m/sec as a hot air velocity under the conditions tested. Under the conditions, the viability of
T. halophila cells was 98.6%.
Development of a dry starter of
T. halophila is expected to provide an easy handling method of handling of the lactic acid bacterium for miso producers.
