- Xerophile
Xerophiles are extremophilic
organism s that can grow and reproduce in conditions with a low availability of water, also known aswater activity .Water activity (aw) is a measure of the amount of water within a that an organism can use to supportgrowth . Xerophiles are often said to be "xerotolerant", meaning tolerant of dry conditions. They can survive in environments withwater activity below 0.8.Endolith s andhalophile s are often xerotolerant.The common food preservation method of reducing water activities may not prevent the growth of xerophilic organisms, often resulting in food spoilage. Many
mold andyeast species are xerophilic.Mold growth onbread is an example of food spoilage by xerophilic organisms.Examples:
