Actinomyces; Thermophilic fungi
The results of this investigation show that a definite relationship exists between the number of actinomycete colonies that develop on a nutrient agar growth medium and the temperature to which the organisms have first been exposed. It is shown that a steady increase in temperature is accompanied by a steady decrease in the number of developing actinomycete colonies. It is also shown that even though a majority of the actinomycete colonies resulting from a 50°C-heated soil sample are mesophilic types, a high percentage—more than one-third— are true thermophiles. Finally, this investigation shows that Actinomycete Isolation agar results in far fewer bacterial and fungal contaminants than does Czapek's growth medium.
