Construction of bottom-fermenting yeasts that over express the ubiquitin ligase RSP5 gene and their effects on high-gravity fermentation

  It has been reported that over expression of the ubiquitin ligase RSP5 gene conferred tolerance to various stresses in laboratory yeast Saccharomyces cereivisiae. We constructed strains of bottom-fermenting yeast, natural hybrid, in which the S. cerevisiae(SC)-RSP5 or Saccharomyces bayanus (SB)-RSP5 is highly expressed and used for high-gravity fermentation. The...

Biodegradable polymer drilling mud prepared from guinea corn

  A biodegradable polymer drilling mud was prepared using Guinea corn starch pre- gelatinized in the absence of a solvent. The filtration and rheological properties of the mud were studied at 25 to 200°C temperature range and 0.01 to 0.05 g/mL concentration of starch using filter loss and viscomertric methods, respectively.  Experimental results showed that the new mud has better filtration control...
