[The Palmier date palm and Fusarium infection. II. Report on the stereochemistry of monosaccharides and their various derivatives and the growth of Fusarium oxysporum f.sp. albedinis (Killian et Maire) Gordon].

Fusarium oxysporum albedinis was grown in the presence of 20 different sugars or their derivatives. The results obtained were correlated with the stereochemical structure of the main oses. Osmotic phenomena as well as active and selective transport were used to explain differences in utilization of oses of very near structure. Based on the affinity of the fungus for mannose, a hypothesis is formulated concerning the fungus action in the host.
