Hormonema. isolate

Botrytis allii converted (+)-pulegone (119) to (-)-(l/ )-8-hydroxy-4-p-menthen-3-one (121) and piperitenone (112) (Miyazawa et al., 1991a, 1991b). Hormonema isolate (UOFS Y-0067) quantitatively reduced (+)-pulegone (119) and (-)-menthone (149a) to (+)-neomenthol (137a) (van Dyk et al., 1998) (Figure 14.125). 

Hormonema species occasionally are confused with Aureoba-sidium spp. In the genus Hormonema, the conidia arise in a basipetal succession from either hyaline or dematiaceous hyphalike conidiogenous cells. In contrast, A. pullulans produces its conidia in a synchronous manner. Because of the confusion which has surrounded these two genera, some of the reported cases of infection ascribed to A. pullulans may have been caused by misidentified isolates of Hormonema spp. This speculation is based upon the fact that several authors have illustrated Hormonema spp. under the name Aureobasidium.
