In vivo stable isotope labeling and computer-assisted metabolic flux analysis were used to investigate the metabolic pathways in petunia (Petunia hybrida) cv Mitchell leading from Phe to benzenoid compounds, a process that requires the shortening of the side chain by a C(2) unit. Deuterium-labeled Phe ((2)H(5)-Phe) was supplied to excised petunia petals. The intracellular pools of benzenoid/phe...

The Urushibara Ni (U-Ni) hydrogenation catalyst and some modified forms, and for comparison Raney-Ni, were subjected to conventional (oil bath) and MW heating, and subsequently characterized by electron dispersive X-ray analysis (EDX), by BET surface area, and by scanning electron microscopy (SEM); yields of the catalyzed hydrogenation of acetophenone to 1-phenylethanol in 2-propanol by one of ...

Continuous operation of alcohol dehydrogenase (ADH) catalysed enantioselective reduction in a biphasic sytem showed gains in productivity and stability of the overall reaction system. The total turnover numbers obtained for the cofactor NADP + are high with up to 1.5 10 4 . Productivity for (R)-2-butanol with Lactobacillus brevis ADH was up to 26 kmol (mol enzyme) 1 . Enantioselectivity was gre...
