Rapeseed meal is a cheap and abundant raw material, particularly rich in phenolic compounds of biotechnological interest. In this study, we developed a two-step bioconversion process of naturally occurring sinapic acid (4-hydroxy-3,5-dimethoxycinnamic acid) from rapeseed meal into canolol by combining the complementary potentialities of two filamentous fungi, the micromycete Aspergillus niger a...
In the present work, we tried to identify mechanism why by which steroid alcohols accumulated when hydroxypropyl-β-cyclodextrin (HP-β-CD) was enhance sterol conversion rate. Compared with bioconversion system without HP-β-CD, reaction rate greatly improved in presence of but largely concurrently. a an enhanced rate, higher intracellular NADH/NAD+ level detected, and production increased also. M...
• EAEP increased extractability and bioaccessibility of soy isoflavone aglycones. phenolic compounds. resulted in extracts with higher antioxidant potential. improved the functional biological properties extracts. The effects enzymatic extraction strategies on extractability, bioconversion, biologically active aglycones, total content, activity aqueous from full-fat flour were evaluated. Protea...
Mary E H Mandels, who spearheaded the US Army's national bioconversion studies for four decades and was an early proponent of conversion of waste biomass to readily bioconvertible sugars for the production of chemicals and transportation fuels such as ethanol, died 17 February 2008 at Natick, MA, USA. She was 90.
The enzymatic bioconversion of xylose into xylitol by xylose reductase (XR) is an alternative for chemical and microbiological processes. The partial purified XR was obtained by using the following three procedures: an agarose column, a membrane reactor or an Amicon Ultra-15 50K Centrifugal Filter device at yields of 40%, 7% and 67%, respectively.
The gene encoding an acetylxylan esterase (AXE1) from the thermophilic ascomycete Talaromyces emersonii was cloned, expressed in Escherichia coli, and characterized. This form of AXE1, rTeAXE1, exhibits increased thermostability and activity at a higher temperature than other known fungal acetyl esterases, thus having huge potential application in biomass bioconversion to high value chemicals o...
