Surprisingly, … Some xerophytes originate in jungle conditions, growing in the tree canopy - these are also referred to as epiphytes ; others are native to deserts, cliffs and other dry climates. Halophiles are all microorganisms. The most halophilic prokaryotes can survive in saturated NaCl, which has an a w value of less than 0.755. Conversely, microbial growth rates decrease rapidly as the temperature is lowered and, hence, food spoilage occurs much more slowly. It has been a Drummond tradition to alternately name the eldest son in each generation, Peter and George, making it a bit confusing to sort out the family tree. http://www.theaudiopedia.com What is XEROPHILE? 125 years later, scientists have shown that the lake is actually teeming with an abundant diversity of microbial life.

SUMMARY The term “alkaliphile” is used for microorganisms that grow optimally or very well at pH values above 9 but cannot grow or grow only slowly at the near-neutral pH value of 6.5. Microorganisms in sea ice were noted by early sailors and first studied as a scientific curiosity by Bunt (1964). Within the growth range, the rate of growth increases rapidly as the temperature is raised (Figure 2). Water has been considered to be a pre-requisite for life but xerophiles can withstand extremely dry conditions with very low water activity. These organisms do not necessarily feed on nutrients from the rock, but they may utilize nutrients found in groundwater. and showed that currently accepted species in Chrysosporium phylogenetically belong in six clades in three orders. thermophiles.
