Direct fermentation of unhydrolyzed potato starch to ethanol by monocultures of an amylolytic fungus, Aspergilus niger, and cocultures ofA. niger and Saccharomyces cerevisiae was investigated. Amylolytic activity, rate and amount of starch utilization, and ethanol yields increased several-fold in coculture versus the monoculture due to the synergistic metabolic interactions between the species....

The effects of acute ethanol administration on blood pressure, heart rate and the baroreceptor reflex control of heart rate were studied in normotensive subjects who served as their own control. Baroreceptor reflex control of heart rate was measured by two methods: the ramp method and the steady state method. None of the doses of ethanol had any effect on blood pressure during the observation p...

In the considered foundry emits offgas containing VOCs (especially ethanol). In order to reduce the VOC content, a compost based biofilter has been installed. In this approach, the polluted air stream enters a pre-conditioning chamber where temperature and humidity is adjusted for asphalt factories. Biofilteration has already been well established as an air pollutant control alternative. There ...

Sixteen healthy volunteers took part in a cross-over study examining the effect of ethanol on the rate of sulphadimidine acetylation (blood ethanol concentration about 1 g/1). In both rapid and slow acetylators the apparent half life of the drug decreased by about 20% after ethanol (mean reduction 39 +/- SE 8 min) and the amount of drug acetylated, measured in blood and urine, increased. In thr...

considered to be the cleanest liquid fuel, bioethanol can be a reliable alternative to fossil fuels. it is produced by fermentation of sugar components of plant materials. the common onions are considered to be a favorable source of fermentation products as they have high sugar contents as well as contain various nutrients. this study focused on the effective production of ethanol from an endem...

High performance liquid chromatography coupled with photodiode array detector (HPLC-DAD) has been reported to quantify isolated flavonoids or these compounds in complex biological matrices, such as Chinese herbal drugs and products from factories. This work was designed, therefore, to develop an HPLC-DAD system to separate quercetin, luteolin and apigenin and to quantify them in extractive solu...

Objective(s): Oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. Licochalcone B, an extract of licorice root, has shown antioxidative properties. This study was to investigate the effects and mechanisms of licochalcone B in ethanol-induced hepatic injury in an in vitro study. Materials and Methods: An in vitro model of Ethanol-induced cytotoxicity in BRL cel...

The yeast cells of Saccharomyces cerevisiae immobilized on Nypa fruticans leaf sheath pieces were tested for ethanol tolerance (0, 23.7, 47.4, 71.0 and 94.7 g/L). Increase in the initial ethanol concentration from 23.7 to 94.7 g/L decreased the average growth rate and concentration of ethanol produced by the immobilized yeast by 5.2 and 4.1 times, respectively. However, in the medium with initi...
