A non-linear kinetic model to predict the consumption of different sugars (glucose, fructose and sucrose) as a substrate, during an apple wine yeast fermentation with Saccharomyces cerevisiae strain CCTCC M201022 is proposed. This was used sugar utilization by this beginning at various initial concentrations. After observation experimental data, based on logistic equation growth, growth-associated production ethanol lag time, for biomass formation maintenance, developed. fitting, parameters...
Flavor volatiles are important components of alcoholic beverages. In this study, headspace solid-phase microextraction and gas chromatography—mass spectrometry (HS-SPME-GC-MS) were investigated for the determination flavor-contributing apple wine. HS-SPME parameters defined, including fiber coatings, extraction time, temperature. Good linearity, recoveries, repeatability SPME method using carboxen-polydimethylsiloxane (carboxen-PDMS) obtained with r2 values, relative standard deviations...
The aim of this study was to enhance the production vitamin K2 by using N-methyl-N-nitro-N-nitroso-guanidine (NTG) and low energy ion beam implantation optimizing fermentation medium. Mutation resulted in 1.66-fold higher than that parentl strain. mutant BN-P15-11-1was increased 55% reached 3.593±0.107 mg/L Plackett-Burman Box-Behnken designs optimize optimal culture medium composed (g/L) glycerol 69.6, sucrose 34.5, K2HPO4 4.0, peptone 20, yeast extract 25 fermented at 37 °C 150 rpm for 72...
Vitamin K2, a natural fat-soluble vitamin, is potent neuroprotective molecule, owing to its antioxidant effect, but mechanism has not been fully elucidated. Therefore, we stimulated SH-SY5Y cells with 6-hydroxydopamine (6-OHDA) in proper dose-dependent manner, followed by treatment of vitamin K2. In the presence 6-OHDA, cell viability was reduced, mitochondrial membrane potential decreased, and accumulation reactive oxygen species (ROS) increased. Moreover, 6-OHDA promoted...
Menaquinone-7 (MK-7), which is associated with complex and tightly regulated pathways redox imbalances, produced at low titres in Bacillus subtilis. Synthetic biology provides a rational engineering principle for the transcriptional optimisation of key enzymes artificial creation cofactor regeneration systems without regulatory interference. This holds great promise alleviating pathway bottlenecks improving efficiency carbon energy utilisation.We used bottom-up synthetic approach redesign...
A method for the preparation of volatile compounds in Changyu XO brandy was established. The were extracted using liquid-liquid extraction and then separated into two fractions, namely, acidic/water-soluble fraction neutral/basic fraction. furthermore 4 fractions silica gel normal phase chromatography, each concentrated analyzed gas chromatography-mass spectrometry (GC-MS). In comparison with pure standards retention indices (RIs) reported literature, a total 302 identified brandy, including...
