Production techniques and market of propionic aldehyde and propionic acid and propanol are introduced in this paper. 本文综述了丙醛、丙酸、丙醇的工艺技术及市场前景。 —— 给力词典精选 4. The direct oxidization directly is forming 2,2-dimethylolbutyraldehyde by anode; ...
1-Propanol production was also detected from the promiscuous activity of the native alcohol dehydrogenase (AdhE). We also show that aerobic conditions are favourable for propionic acid production. Finally, we increase titre 65 times using a combination of promoter engineering and process optimisation. ...
When 3-nitropropanol (NPOH) was injected into the rumen (30 mg/kg), abomasum (10 mg kg) or small intestine (10 mg/kg) of sheep, it was rapidly absorbed and converted to 3-nitropropionic acid (NPA). The reticulo-rumen was the major site of absorption for the miserotoxin aglycone but...
