| Abstract: | Strains of different origins belonging to the two species of fungi imperfecti Cylindrocarpon ianothele and Calcarisporium arbuscula exhibit difference in their morphological or physiological appearances. We have attempted to determine if these variabilities could also be observed at the level of other phenotypic markers, the enzymes glucose-6-phosphate dehydrogenase, alcohol dehydrogenase, octanol dehydrogenase and malate dehydrogenase. Isozymes were separated by polyacrylamide gel electrophoresis and demonstrated isozyme variability as a function of growth and physiological states of a given strain. At the same state of development, the different strains exhibited highly heterogeneous isozyme groups which appear difficult to use for taxonomic purposes. |
