Saccharomyces cerevisiae M30, a high ethanol producing flocculent strain, was hybridized with Zygosaccharomyces rouxii TISTR1750, a halotolerant non-flocculent strain, by polyethylene glycol induced protoplast fusion. The protoplast fusion of these two yeast genera occurred with frequency of 5.89X10-5. Three fusants, namely RM11, RM37 and RM58, were selected based on their high ethanol fermenta...

The behaviour of the flocculent Kloeckera apiculata strain in coculture with the nonflocculent Saccharomyces cerevisiae strain, both yeasts isolated from wine, has been analyzed. Pure culture of Kloeckera apiculata (apiculate yeast) exhibits 75 % flocculation in the yeast extract/peptone/glucose (containing 20 g/L of glucose, YPG20) medium after 24-hour incubation at 28 °C. This yeast expresses...

Lignin fibers typically influence the mixture performance of stone matrix asphalt (SMA), such as strength, stability, durability, noise level, rutting resistance, fatigue life, and water sensitivity. However, limited studies were conducted to analyze the influence of fibers on the percent voids in mineral aggregate in bituminous mixture (VMA) during the mixture design. This study analyzed the e...

OBJECTIVES To evaluate the effectiveness of point of use water treatment with flocculent-disinfectant on reducing diarrhoea and the additional benefit of promoting hand washing with soap. METHODS The study was conducted in squatter settlements of Karachi, Pakistan, where diarrhoea is a leading cause of childhood death. Interventions were randomly assigned to 47 neighbourhoods. Households in 1...

Gas and stars in spiral galaxies are modelled with the dual code, using hydrodynamic and N-body techniques. The simulations reveal morphological differences mirroring the dual morphologies seen in B and K ′ band observations of many spiral galaxies. In particular, the gaseous images are more flocculent with lower pitch angles than the stellar images, and the stellar arm-interarm contrast correl...
