Chiral Phosphinate Degradation by the Fusarium Species : Scope and Limitation of the Process

الملخص EN

Biodegradable capacities of fungal strains of Fusarium oxysporum (DSMZ 2018) and Fusarium culmorum (DSMZ 1094) were tested towards racemic mixture of chiral 2-hydroxy-2-(ethoxyphenylphosphinyl) acetic acid—a compound with two stereogenic centres.

The effectiveness of decomposition was dependent on external factors such as temperature and time of the process.

Optimal conditions of complete mineralization were established.

Both Fusarium species were able to biodegrade every isomer of tested compound at 30°C, but F.

culmorum required 10 days and F.

oxysporum 11 days to accomplish the process, which was continuously monitored using the 31P NMR technique.
