Stachybotrys spp

If any filters or straining bags made firm natural materials such as canvas, muslin or paper are used, care must be taken to ensure that they are cleaned and sterilized regularly to prevent the growth of moulds such as Cladosporium spp., Stachybotrys spp., ardAureobasidium (Pullularia)pullulans, which utilize cellulose and would impair them. 

The trichoverroids and fungal macrocycles are products of Myrothecium and Stachybotrys spp., and one species each of Acremonium, Ceratopycnidium, Cercophora, Cylindrocarpon, Phoma, Phomopsis, and Verticinimonosporium. Acremonium, Ceratopycnidium, Cercophora and Phoma are new sources reported since 1991. 

The simple trichothecenes are products of Acremonium, Fusarium, Myrothecium, Stachybotrys and Trichoderma spp., and one species each of Cephalosporium, Cylindrocladium, Dendrostilbella, Gliocladium, Memnoniella, Microdocium, Spicellum and Trichothecium. Trichothecium roseum is, nevertheless, responsible for 12 metabolic products with... 

Trichodiene (49 Scheme 1) has been detected as a volatile product of Monascus purpureus and of Stachybotrys atra, but the trichothecene relatives (Table 8), including, possibly, the loukacinols (see note c), are essentially products of Fusarium spp. and T. roseum. 

Trichodiene (49), the last hydrocarbon intermediate in the pathway, has been isolated from T. roseum, from Fusarium spp., and also from S. atra (Table 8). Specific labelling experiments have shown it to be a precursor of trichodiol (55) and 12,13-epoxy trichothecene (73), in addition to trichothecolone (101), in T. roseum (277) it is also a precursor of isotrichodiol (53) (219) and 3-acetylvomitoxin (104) in F. culmorum (278). However, relatively little work has been done on this stage of the pathway to simple trichothecenes in Myrothecium, Stachybotrys and Trichoderma spp.
