Symbiotic interrelationships of a pair of mesophilic and thermophilic bacilli

Physiological and taxonomic aspects of Clostridium thermocellum

“…More recently (Ljunger, 1968) , obligate thermophilic bacteria have been reported that grow at mesophilic temperatures when inhibitory substances are removed from the growth medium. But to the knowledge of the author the work of Oates et (1961Oates et ( , 1963Oates et ( , 1964 was the first known report of a mesophile being able to grow at elevated temperatures; however, recent work by Dowden et al (1968) suggests that a mesophilic strain of Bacillus subtilis can be adapted to grow at elevated tempera tures .…”
