Improved cadmium resistance and removal capacity in Pichia kudriavzevii A16 by sucrose preincubation.

abstract：:The fungal population of Aswan High Dam Lake showed marked vertical variations during the period of study which extended from July 1985 to December 1986. High fungal counts were observed at the surface water which were mainly due to the high counts of Aspergillus fumigatus and A. terreus. Going deeper the fungal popul...
