Continuous fermentations were carried out with a recombinant flocculent Saccharomyces cerevisiae strain in an airlift bioreactor. Once operating under steady state at a dilution rate of 0.45 h(-1), the bioreactor was contaminated with Escherichia coli cells. The faster growing E. coli strain was washed out of the bioreactor and the recombinant, slower growing flocculating S. cerevisiae strain r...

ZnCl2 forms a 1 : 1 double salt with phosphatidylcholine. This compound resembles the long-known double salt of CdCl2 and phosphatidylcholine except that the latter has the composition (CdCl2)3(phosphatidylcholine)2. Treatment of phosphatidylcholine with a mixture of equimolar amounts of ZnCl2 and CdCl2 yields the ZnCl2 double salt. The ZnCl2 double salt can be obtained as an amorphous floccule...

Koch (1886) studied the effect of cholera vibrios on guinea-pigs by feeding the animals with big doses of the organisms and then paralysing the gut by intraperitoneal injection of 1 c.cm. of tincture of opium so as to delay evacuation. Out of 35 animals, 30 died showing weakness of the hind limbs and collapse. The small intestine was deeply injected and filled with a;flocculent colourless fluid...

In this study, the degree of goodness fit presented by San model is determined to calculate percentage removal flocculent particles, when initial turbidity in problem water low. For this, frequency analysis historical data that enters four drinking treatment plants located department Cundinamarca (Colombia) made, which show values range between 0.60 and 15.08 NTU (Nephelometric Turbidity Units)...

Sulfamethoxazole is a widely—used antibiotic with high water solubility and low biodegradability, which was considered refractory environmental pollutant. Hence, series of functionalized hybrids uniting Cu3P TiN were prepared. The Cu3P/TiN—x composites remarkably removed the sulfamethoxazole in solution compared alone. All as—prepared integrated advantages strong adsorption photocatalysis achie...
