Fungi linalool

The biotransformation of (/f,5)-Iinalool by fungi is a useful method for the preparation of natural linalool oxides. The stereospecific conversion of (J ,5)-linalool by Corynespora cassiicola DSM 62475 led to 5/f-configured furanoid linalool oxides and 55-configured pyranoid linalool oxides, both via bS -configured epoxylinalool as postulated intermediate (Figure 12.6). The biotransformation protocol affords an almost total conversion of the substrate with high enantioselectivities and a molar conversion yield close to 100% (Table 12.4). Pure linalool oxides are of interest for lavender notes in perfumery. ... 

Yeast, fungi, insects widespread among higher plants. (-)-linalool >80% in Shiu oils (Cinnamomum camphora) (+)-linalool 60-70% in coriander oil. 

In the eighties, the bioconversion of monoterpene alcohols by fungi had not been studied intensively [32]. However, a strain of Aspergillus niger was isolated from garden soil, able to transform geraniol, citronellol and linalool to their respective 8-hydroxy derivatives. This reaction was called fu-hydroxylation [39,40]. 

Adding S. fruticosa Mill. (Lamiaceae) compost to soil decreases the high C/N rates and raises the pH of the soil. Moreover, it increases the number of microbes in the soil, such as bacteria and fungi (Chalkos et al, 2010). S. sclarea (Lamiaceae) volatile oil s compounds are linalyl acetate, linalool, geranyl acetate, and a-terpineol. The essential oil is able to cause fungicidal activity on S. sclerotiorum, a soilborne pathogen. It also inhibits growth of Sclerotium cepivorum and Fusarium oxysporum f.sp. Dianthi (Pitarokili et al., 2002).
