MUSÍLKOVÁ M., FENCL Z., UJCOVÁ E., SEICHERT L. (1979): The viability and physiological activity of spores of Aspergillus niger under different methods of preservation. Česká Mykologie 33(3): 181-184 (published: 1979)
abstract
Spores of the Aspergillus niger mutant MBU 90, producing high quantities of citric acid under submerged conditions, will keep their viability during a period of 4 years when stored in talc or in lyophilized form (using inactive horse serum or dried milk). When spores are stored in active coal a decrease in spore viability was noted after 3–4 years of storage. Moreover, an increase in the frequency of different morphological modifications was observed.
