Abstract: The present disclosure generally relates to the production of natural vanillin by biocouversion using isoeugenol as the substrate. More specifically, the present methods utilize a filitgal isoeugenol monooxygenase to catalyze the bioconversion of isoeugenol to vanillin, which can be carried out in a cellular system (e.g., bacteria or yeasts) or in an enzymatic reaction mixture without a cellular system.

Abstract: The present disclosure generally relates to the production of natural vanillin by bioconversion using isoeugenol as the substrate. More specifically, the present methods utilize a fungal isoeugenol monooxygenase encoded by VpIEM gene from Violaceomyces palustris to catalyze the bioconversion of isoeugenol to vanillin, which can be carried out in a cellular system (e.g., bacteria or yeasts) or in an enzymatic reaction mixture without a cellular system.

Abstract: The present invention relates to methods and transformed host cells for the production of eriodictyol from naringenin via bioconversion.

Abstract: An ultrasonic probe coupling assembly (1) and an ultrasonic probe mechanism are disclosed. The ultrasonic probe coupling assembly (1) includes a probe sleeve (11) and a solid-state coupling member (12). The probe sleeve (11) is sleeved on an ultrasonic probe (2). The solid-state coupling member (12) is fixed in the probe sleeve (11). One side of the solid-state coupling member (12) is located in the probe sleeve (11) for fitting to the ultrasonic probe (2), and the other side is protruded from the probe sleeve (11) to be in contact with the skin. The ultrasonic probe mechanism includes the ultrasonic probe coupling assembly (1) and the ultrasonic probe (2).

Abstract: The present invention relates to the production of vanillin via the bioconversion of isoeugenol. The bioconversion can be mediated in a cellular system (e.g., an Escherichia coli bacterium), or in an enzymatic reaction mixture without a cellular system.
