Octylphenol (OP) is an estrogenic detergent breakdown product. Structurally similar nonylphenols are transformed via type II ispo substitution, resulting in the production of hydroquinone and removal of the branched side chain. Nothing is known, however, about the gene(s) encoding this activity. We report here on our efforts to clone the gene(s) encoding OP(More)
A comparison of testing methods for constituents of Ginkgo biloba was performed as part of the process for determining which of the many available analytical methods was most appropriate for inclusion in the American Herbal Pharmacopoeia (AHP). Three primary methods were reviewed: those adopted by the European Pharmacopoeia, the National Science(More)
We previously showed that opdA from Sphingomonas sp. PWE1 encodes a putative flavin monooxygenase capable of transforming octylphenol (OP) via type II ipso substitution. Here, we demonstrate that an opdA homolog is responsible for OP and related alkyl/alkoxyphenol degradation in the nonylphenol degrader Sphingomonas sp. TTNP3. PCR and Southern blot analyses(More)
The lack of deployed wave farms means direct measurement of the effects of Wave Energy Converter (WEC) arrays on near-field and nearshore wave propagation is not possible. As a result, environmental impacts of wave farms are largely determined through simulations using numerical wave models. Sandia National Laboratories has developed the SNLSWAN code, an(More)
