MUSÍLKOVÁ M., UJCOVÁ E., SEICHERT L., SIKYTA B., KRUMPHANZL V. (1982): A comparison of the effect of mutagens on a high citric acid producing strain of Aspergillus niger. Česká Mykologie 36(1): 47-51 (published: 1982)
abstract
Effects of three mutagens on spores of Aspergillus niger NG 233 were compared. After treatment with UV light and N-Methyl-N’-nitro-N-nitrosoguanidine, significant differences of citric acid production amongst isolates were detected; N-Ethyl-N-nitrosourea was the least effective mutagen. A maximum increase of 13% over the high productivity of the original strain was recorded for UV light as mutagen. In general, storage of spores decreased the activity of a series of strains with the exception of the isolate UV 6, which retained its activity of citric acid production.
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.
MUSÍLKOVÁ M., MUSÍLEK V., ŠAŠEK V. (1975): Release of yeast spheroplasts by an enzyme complex from Lycoperdon perlatum Pers. ex Pers. Česká Mykologie 29(3): 153-156 (published: 1975)
abstract
Fruit bodies of some Basidiomycetes, e.g. Lycoperdon periatum, contain enzymes capable of destroying cell walls of yeasts and filamentous fungi, thereby releasing spheroplasts. A lyophilized enzyme preparation from L. periatum remained active over long storage in cold. The study elaborates on the potential of lytic enzyme complexes from higher fungi for degrading the cell walls of viable yeast cells.
