Isolation and Analysis of the Enzymatic Properties of Thermophilic Fungi from Compost
To the best of our knowledge, this is the first report on thermophilic fungi isolated in Korea. Three species of thermophiles were isolated from compost and were identified as Myriococcum thermophilum, Thermoascus aurantiacus, and Thermomyces lanuginosus. They can grow at temperatures above 50 o C and produce high levels of cellulolytic and xylanolytic enzymes at high temperatures. Notably, the considerable thermostability of the endo-glucanase produced by T. aurantiacus has made the fungus an
... ttractive source of industrial enzymes. Thermophilic fungi can grow at temperatures ranging from a minimum of 20 o C to a maximum of 50 o C or at even higher temperatures. Thermophilic species are present in the natural environment in composts, aquatic sediments, piles of hay, stored grains, wood chip piles, and other accumulations of organic matter wherein the conditions are warm, humid, and aerobic  . A number of thermophilic fungi can survive in harsh conditions such as those with increased water pressure, an absence of oxygen, and under desiccation  . In a previous study, most thermophiles were isolated from composts ; their prevalence in composts can be explained by the high temperatures, humidity, and aerobic conditions within the compost. Moreover, the supply of carbohydrates and nitrogen in this mass of organic matter favors the development of thermophilic microflora . Research Note Mycobiology 2014 June, 42(2): 181-184 http://dx.
