Summary
Three different systems (bacterial, fungal, and yeast) of microbial
degradation of cellulose have been described. At the present state of the art,
the most promising technology is singlecell protein production by Aspergillus
terreus. Continuous cultivation of Aspergillus terreus on treated solka-floc
with more than 80 per cent utilization of cellulose indicates that SCP
production from cellulose is economically feasible on a commercial scale. The
importance of basic studies on the physiology of the organism under conditions
of continuous cultivation in a chemostat was
discussed.
