Biochemistry of plant diseases

Abstract

When this organism is grown on xylose, arabinose, or rhamnose as sources of C, the main products of metabolism are mycelium, CO2, ethyl alcohol, and a small amount of organic substance precipitated by lead. Previous work (Anderson, Univ. of Minnesota Studies in Biol. Sci. No. 5, 1924) indicated that some other main product might exist. Since 95 to 99% of the C can be accounted for in the above products, it is unlikely that there is any other of major importance. Of these pentoses, xylose is utilized the most efficiently for alcohol production and arabinose for growth. Rhamnose is utilized very poorly for either. During the course of growth in a culture the ratio of CO2 to alcohol constantly shifts, due largely to consumption of alcohol by the fungus.
