The influence of some pentoses on the ability of the fungus Ophiostoma multiannulatum to grow on d ‐galactose was investigated. There is no measurable growth of the wild type Ophiostoma when galactose is the sole carhon source, d ‐xylose has a stimulating effect on the utilization of galactose in this fungus. Even when d ‐xylose is added in low concentrations as compared to the concentration of galactose in the mixtures the growth‐promoting effect is high. The xylose can be added in amounts which are directly growth‐limiting. The addition of l ‐arabinose also results in growth on gatactose if the concentration ratio arabinose: galactose is selected high enough. The results are discussed and compared to previously published data on stimulating effects from other hexoses on the utitization of galactose in this fungus.
