Oxidation of linear terpenes and squalene variants by Arthrobacter sp

Cells of Arthrobacter sp. that had been isolated from soil were used to study oxidation of some linear terpenes and squalene variants. The cells oxidized geraniol, nerol, and farnesol to the corresponding aldehydes, with partial conversion of the geometrical isomerism of the alpha,beta-double bond. The squalene variant, squalene-2,3-oxide, was cleaved to 9,10-epoxygeranylacetone and geranylacetone. Squalene-2,3-22,23-dioxide was cleaved to 9,10-epoxygeranylacetone. These products were optically active, and their stereochemistry and optical purity were determined.
