3.2 Physiological characteristics
3.2.1 Growth at various temperature
In all film yeast strains were tested the ability to grow at 0, 40, 50, 60, 70 and 80 oC. These film yeasts can grow at low temperature but they were not survived at higher than 60 oC within 15 min (Table 3). It was quite sensitive to heat. These results are also found in some yeasts spoilage which isolated from syrups and candied fruit nougats are a capability displayed at 37 oC. All strains tested were killed at 43 and 52.5 oC (14). This observation indicates that the ability of temperature at 60 oC or more had potential for control spoilage yeasts in food preservation.
