[Effect of nitrogenous sources on the growth and morphogenesis of Scopulariopsis brevicaulis Bainier].
Growth and morphology of hyphae grown on a synthetic amino-acid supplemented medium were compared with those grown on a control medium. Dry weight was lower in the amino-acids-containing medium and some ultrastructural changes were observed. Cell wall thickness increase, and the cultures were seen to colonize the cellophane support. These observations may be related to a physiological requirement of this organism when grown on amino-acids of keratin.
