This invention relates to the bioproduction of substituted or unsubstituted phenylacetaldehyde, 2-phenylethanol, phenylacetic acid or phenylethylamine by subjecting a starting material comprising glucose, L-phenylalanine, substituted L-phenylalanine, styrene or substituted styrene to a plurality of enzyme catalyzed chemical transformations in a one-pot reaction system, using recombinant microbial cells overexpressing the enzymes. To produce phenylacetaldehyde from styrene, the cells are modified to overexpress styrene monooxygenase (SMO) and styrene oxide isomerase (SOI). To produce phenylacetic acid from styrene, SMO, SOI and aldehyde dehydrogenase are overexpressed. Alternatively, to produce 2-phenylethanol, SMO, SOI and aldehyde reductase or alcohol dehydrogenase are overexpressed, while to produce phenylethylamine, SMO, SOI and transaminase are overexpressed.

Bioproduction of phenethyl alcohol, aldehyde, acid, amine, and related compounds

Method and apparatus for receiving coded signals with the aid of CSI are provided. The method comprises: performing channel estimation to obtain a CFR estimation vector; computing a squared magnitude of the CFR estimation vector, and obtaining a normalization factor &#x3b1; by averaging the squared magnitudes of CFR estimations on all N subcarriers; finding a norm-shift operand m satisfying the condition that &#x3b1;=2is a power of 2 number closest to the normalization factor &#x3b1;; performing a CSI-aided one-tap channel equalization on an output signal vector from a DFT processor by using the norm-shift operand m; performing constellation demapping; and performing channel decoding. The method further comprises obtaining a weighting factor vector by right shifting m bits of the squared magnitude of the CFR estimation vector so that the constellation demapping can use the weighted decision boundary values in case that its input signal is sensitive to both amplitude and phase.
