Two bacteria were isolated from sand RQ30, characterized as Bacillus simplex and Bacillus sp. strain 05 (GenBank EU399813), and were used as biocatalysts for a hydrolytic assay of stability of the cis or trans isomers of ethyl N-2-4-[2-(butanoyl)oxycyclohexyl]methyl}phenoxy}ethyl}carbamate, which are among insect hormonogen substances (juvenogens). The stability tests were performed using simple modeling under laboratory conditions. The structures of the products were assigned as ethyl (1R,2R)-N-2-4-[(2-hydroxycyclohexyl)methyl]phenoxy}ethyl}carbamate and ethyl (1S,2R)-N-2-4-[(2-hydroxycyclohexyl)methyl]phenoxy}ethyl}carbamate on the basis of H-1 and C-13 NMR, IR, and FAB-MS analyses.
