The mechanism of repression of induction of nitrate reductase by ammonium in fungal systems is not understood. It has been suggested (Dantzig et al., 1978 Premakumar et al., 1978 Subramanian et al., 1%8) that glutamine or... 

The mechanistic aspect of the fungal reduction of metal ions led by colloidal suspension is still an open question. However, in the fungal case, this process occurs probably either by reductase action or by electron shuttle quinines, or both. To elucidate the mechanism of nanoparticles formation, a novel fungal/enzyme-based in vitro approach was for the first time explained by Mukherjee et al. (2002). They successfully used species-specific NADH-dependent reductase, released by the F. oxysporum, to carry out the reduction of AuClJ ions to gold nanoparticles. Duran et al. (2005) later reported that the reduction of the metal ions occnrs by a nitrate-dependent reductase and a shuttle quinone extracellular process. The same...
