| oxalate production by wood-rotting fungi growing in toxic metal-amended medium. | in this report, we have identified oxalic acid as an important metabolite elaborated in the response of wood-rotting fungi to toxic metal stress. the formation of oxalate crystals by white rot fungi (bjerkandera fumosa, phlebia radiata and trametes versicolor) and the brown rot fungus fomitopsis pinicola, grown on media containing high levels of toxic metal ions has been visualized using scanning electron microscopy (sem) with energy-dispersive x-ray micro-analysis (edxa) and hplc. there were no ... | 2003 | 12738291 |
| oxalic acid, versatile peroxidase secretion and chelating ability of bjerkandera fumosa in rich and limited culture conditions. | efficient ligninolytic systems of wood-degrading fungi include not only oxidizing enzymes, but also low-molecular-weight effectors. the ability of bjerkandera fumosa to secrete oxalic acid and versatile peroxidase (vp) in nitrogen-rich and nitrogen-limited media was studied. higher activity of vp was determined in the nitrogen-limited media but greater concentration of oxalic acid was observed in the cultures of b. fumosa without nitrogen limitation. ferric ions chelating ability of bjerkandera ... | 2011 | 21892253 |
