[Thermophilic Myceliophthora thermophila decomposes cellulose].

A thermophilic microscopic fungus was isolated from cattle rumen and identified as Myceliophthora thermophila (Apinis) van Oorschot. The culture synthesized cellulolytic enzymes and xylanase when it was grown in media containing cellulase at 50 degrees C under the conditions of submerged cultivation. The morphological and physiological characteristics of the culture are described and its taxonomic position is discussed.

[Biosynthesis of cellulolytic enzymes and xylanase during submerged cultivation of the fungus Aspergillus terreus 17P].

The fungus Aspergillus terreus 17P--producer of cellulolytic enzymes--was cultivated in the Biotec 10 l fermenter on the medium containing minced and heated (at 200 degrees) wheat straw aerated with a different rate. At the mixing rate of 350 rpm and aeration rate of 0.7 r/rpm on the fourth day the culture liquid was obtained whose filtrate contained an active complex of cellulolytic enzymes and xylanase: CI--3.
