Two isolates of Sclerotinia sclerotiorum , the highly aggressive (B24) and the weakly aggressive (SS41), were grown on liquid media containing one of the following carbon sources: purified cell walls obtained from onion or sunflower, pectin, polygalacturonic acid, carboxymethylcellulose, xylan or arabinogalactan. Isolates were equally able to utilize these substrates for mycelial growth but differed in their ability to utilize them for oxalate production. B24 produces oxalic acid always to a substantial extent, SS41 only in traces. The poor ability to produce oxalic acid by SS41 seems to be due to a lower efficiency in the synthetic pathway.
