According to Collins and Hartlein (1982), lactobacillus growth rate declines rapidly (from more than one generation per hour at optimum to less than one generation per day) below about 15 C and above 55 C or so, but survivorship and optimal temperature vary among strains. At 63 C, almost 93% of one strain died while less than 30% of individuals of another strain died at this temperature.
On the cold end of the spectrum, freezing seems to be okay. Lactobacilli survive cryopreservation and freeze-drying. Although they won't die, their growth is predicted to stop absolutely around -4 C (Wijtzes et al, 1995).

What are the side effects of lactobacillus ferment when in contact in skin?
Lactobacillus ferment is a compound created by the fermentation of the Lactobacillus bacteria. It is used in skin treatments like acne since the good bacteria will help cut back on the bad acne causing bacteria.
Does a lactobacillus have animal cells?
No. They are bacteria and all bacteria are prokaryotes not eukaryotes.
Why does milk sour faster at room temperature than when refrigerated?
When milk is left at room temperature the reason it spoils is due to the bacteria in the air. The bacteria called Lactobacillus converts the lactose in milk into lactic acid which makes it sour. When milk is refrigerated the bacteria growth is prevented.
What is the name of bacteria use in the formation of yogurt?
Lactobacillus bulgaricus and Streptococcus thermophilus are the two main types of bacteria used in the fermentation of yogurt. They convert lactose (milk sugar) into lactic acid, which gives yogurt its tangy flavor and helps in the thickening process.
