title: Cell wall analysis in Aspergillus niger strains characterized by different tolerance to toxic compounds of beet molasses.
abstract: Aspergillus niger strains, sensitive or resistant to toxic compounds of beet molasses, were the object of the present studies. Between the studied strains differences existed in the cell wall dry mass and wall components content, chitin synthesis, activity of enzymes involved in cell wall synthesis, and in the wall ultrastructure. Higher content of proteins and lipids but lower of glucan and chitin; less or lack of fibrillar components, thinner cell wall as well as lower level of glucanase and chitinase, diminished [3H] glucosamine incorporation into cytoplasm and cell wall characterized the sensitive strains of A. niger.
