 Title    Über die Bildung von Cholesterin durch Botrytis cinerea nach Lanosterinzugabe The Production of Cholesterol by Botrytis cinerea after Addition of Lanosterol  
 Abstract    The fungus Botrytis cinerea, which is found on the grapes, is able to produce cholesterol after addition of lanosterol to the culture medium. The identification o f cholesterol is carried out with different analytical methods including mass spectrometry. U nder the same conditions ergosterol arises from squalene and not cholesterol.

 Title    Oxidative Metabolism of Ambrox and Sclareolide by Botrytis cinerea  
 Abstract    Ambrox (1), a perfumery diterpene, was oxidatively metabolised by a plant pathogenic fungus Botrytis cinerea in a xenobiotic fashion to afford a major product, i.e., lß-hydroxy-8-epiambrox (13) (60%) along with three minor metabolites 3ß-hydroxyambrox (2), sclareolide (5) and 3ß-hydroxysclareolide (7). Sclareolide (5), a cytotoxic diterpenoidal lactone was fer­ mented with the same fungus to yield 3ß-hydroxysclareolide (7) (59%) as a major metabolite together with two minor metabolites characterised as 1-ketosclareolide (15), and 3ß,14-dihy-droxysclareolide (16).

 Title    Isolierung und Identifizierung von Sterinen im Metabolismus des Pilzes Botrytis cinerea  
 Abstract    The fungus Botrytis cinerea, which belongs to the class of ascomycetes, has been analysed for its sterol composition. It is able to produce ergosterol, cerevisterol, lanosterol/dihydrolanosterol and cholesterol besides /2-sitosterol. The identification o f the sterols is carried out with different a n a­ lytical methods including mass spectrometry. In the extracts of the mycelium also squalene has been identified.

 Title    Transformationen von trans-2-Hexenal durch Botrytis cinerea PERS. als Entgiftungsmechanismen Transformations of trans-2-H exenal by Botrytis cinerea PERS. as Detoxification M echanisms  
 Abstract    The m etabolization of /rö«5-2-hexenal — one of the main components of plant wound gases with antibiotic activity — was investigated for 5 different isolates of Botrytis cinerea PERS. The transform ation products as well as the kinetics of their formation were analyzed. Isolates exclusively mycelium forming (Be 1 and Be 13) transform ed rr-2-hexenal into tr-2-hexenol, while sporulating isolates (Be 3, Be 9 and Be 10) converted rr-2-hexenal to hexanol-1. Basically the m etabolization of rr-2-hexenal proceeded in the same way via the aqueous phase as in the gas phase. The transform ation products fr-2-hexenol and hexanol-1 showed significantly lower toxicity against the tested B. cinerea isolates than ?/--2-hexenal. In each isolate the end product of tr-2-hexenal conversion had the weakest inhibitory activity. The transform ation reactions thus repre­ sent detoxification mechanisms for these fungi.

 Title    Biotransformation of Two Cytotoxic Terpenes, a-Santonin and Sclareol by Botrytis cinerea  
 Abstract    Two cytotoxic terpenes, a-santonin (1) and sclareol (3) were biotransformed by a plant pathogenic fungus Botrytis cinerea to produce oxidized metabolites in high yields. a-Santonin (1) on fermentation with the fungus for ten days afforded a hydroxylated metabolite iden­ tified as llß-hydroxy-a-santonin (2) in a high yield (83%), while sclareol (3) was metabolized to epoxysclareol (4) (64%) and a new compound 8-deoxy-14,15-dihydro-15-chloro-14-hy-droxy-8,9-dehydrosclareol (5) (7%), representing a rare example of microbial halogenation.

 Title    Substrate Specificity in the Fungal Metabolism of Prenylated Flavonoids  
 Abstract    The prenylated flavonoids, topazolin [5,7,4'-trihydroxy-3-methoxy-6-(3,3-dimethylaIlyl)-flavone], piscerythrone [5,7,2',4'-tetrahydroxy-5'-methoxy-3'-(3,3-dimethylallyl)isoflavone] and piscidone [5,7,4',5'-tetrahydroxy-2'-methoxy-6'-(3,3-dimethylallyl)isoflavone] were meta­ bolized by Aspergillus flavus and Botrytis cinerea to give a variety of products. Topazolin and piscerythrone were converted by both fungi to com pounds similar to those previously ob­ tained from luteone (6-prenyl) and licoisoflavone A (3'-prenyl) respectively. The 6'-prenylated isoflavone piscidone was metabolized only by B. cinerea to give the corresponding dihydro-pyrano-isoflavone as a m ajor product. N either fungus was found to metabolize the 8-prenylated pyranoflavanonol lupinifolinol.
