Impact Of Carbon Sources On Growth And Oxalate Synthesis By The Phytopathogenic Fungus Sclerotinia Sclerotiorum, Bryan J. Culbertson, Jaymie Krone, Erastus Gatebe, Norbert C. Furumo, Steven L. Daniel
Impact Of Carbon Sources On Growth And Oxalate Synthesis By The Phytopathogenic Fungus Sclerotinia Sclerotiorum, Bryan J. Culbertson, Jaymie Krone, Erastus Gatebe, Norbert C. Furumo, Steven L. Daniel
Steven L. Daniel
The impact of various supplemental carbon sources (oxalate, glyoxylate, glycolate, pyruvate, formate, malate, acetate, and succinate) on growth and oxalate formation (i.e., oxalogenesis) by Sclerotinia sclerotiorum was studied. With isolates D-E7, 105, W-B10, and Arg-L of S. sclerotiorum, growth in an undefined broth medium (0.1% soytone; pH 5) with 25 mM glucose and 25 mM supplemental carbon source was increased by the addition of malate and succinate. Oxalate accumulation occurred in the presence of glucose and a supplemental carbon source, with malate, acetate, and succinate supporting the most oxalate synthesis. With S. sclerotiorum Arg-L, oxalate-to-biomass ratios, an indicator of oxalogenic …

Impact Of Nutritional Supplements And Monosaccharides On Growth, Oxalate Accumulation, And Culture Ph By Sclerotinia Sclerotiorum, Steven L. Daniel, Bryan J. Culbertson, Norbert C. Furumo
Impact Of Nutritional Supplements And Monosaccharides On Growth, Oxalate Accumulation, And Culture Ph By Sclerotinia Sclerotiorum, Steven L. Daniel, Bryan J. Culbertson, Norbert C. Furumo

Sclerotinia sclerotiorum D-E7 was studied to determine the impact of nutritional supplements and monosaccharides on growth, oxalate accumulation, and culture pH in broth media (initial pH c. 5). Cultures with 0.1% nutritional supplement (tryptone, yeast extract, or soytone) yielded minimal growth, 2–3 mM oxalate, and a final culture pH of 4.2–4.8. In contrast, cultures with 0.1% nutritional supplement and 25 mM glucose yielded significant growth, minimal oxalate (<1 mM), and a final culture pH of 2.8–3.7. Similar trends were observed when glucose in 0.1% soytone cultures was replaced with 25 mM d-mannose, l-arabinose, or d-xylose. With 1% soytone-25 mM glucose cultures, growth and oxalate accumulation (∼21 mM) occurred with little change in initial pH. This was not the case with 1% soytone-250 mM glucose cultures; increased glucose levels resulted in a decrease in oxalate accumulation (∼7 mM) and in final culture pH (3.4). Time-course studies with these cultures revealed that oxalate accumulation was suppressed during growth when the culture pH dropped to <4. Overall, these results indicate that (1) the decrease in external pH (i.e. acidification) was independent of oxalate accumulation and (2) acidification coupled to glucose-dependent growth regulated oxalate accumulation by Sclerotinia sclerotiorum.
