Effects of Temperature and Relative Humidity on the Growth of and Enzyme Production by Actinomucor taiwanensis during Sufu Pehtze Preparation.

abstract：:The effects of water activity (aw, 0.955 to 0.970), pH (4.75 to 5.75), and storage time (up to 60 days) on toxin production by Clostridium botulinum in cooked, vacuum-packed potatoes were studied by using factorial design experiments and most-probable-number methodology. Samples were inoculated with 10(3), 10(4), or 1...
