The study was performed in a batch system in order to determine the effects of pH and temperature on growth and glycerol production kinetics of two indigenous wine yeast strains Saccharomyces cerevisiae Kalecik 1 and Narince 3. The highest values of dry mass and specific growth rate were obtained at pH 4.00 for both of the strains. Maximum specific glycerol production rates were obtained at pH 5.92 and 6.27 for the strains Kalecik 1 and Narince 3, respectively. Kalecik 1 strain produced maximum 8.8 gL -1 of glycerol at pH 6.46. Maximum glycerol concentration obtained by the strain Narince 3 was 9.1 gL -1 at pH 6.48. Both yeasts reached maximum specific growth rate at 30ºC. Optimum temperature range for glycerol production was determined as 25-30ºC for the strain Kalecik 1. The strain Narince 3 reached maximum specific glycerol production rate at 30ºC. Maximum glycerol concentrations at 30ºC were obtained as 8.5 and 7.6 gL -1 for Kalecik 1 and Narince 3, respectively.

“…Phospholipids were determined in either the Folch extract or the plasma by the method of Zilversmit and Davis (1950). A direct chemical method for estimating triglycerides was employed using the extraction procedure of Oarlson (1963) combined with the hydrolysis procedure of van Handel and Zilversmit (1957), the resultant glycerol content being determined according to the method of Lambert and Neish (1950).…”

SummaryPlasma lipids have been studied in 77 British (Hereford and Shorthorn), 23 Brahman, 63 Brahman X British, 35 Africander, and 182 Africander X British grazing cattle. Cholesterol, phospholipid, and total lipid levels were significantly (P < 0·001) higher in Zebu breeds than in British breeds. The proportion of cholesterol present in the free state was relatively constant and given by the regression equation:where F = amount of cholesterol present in the free state and T is the total amount of cholesterol.Cholesterol and phospholipid levels were significantly higher (P < 0'01) in females than in males. Age was not a primary factor affecting the plasma lipid levels of adult cattle. Highly repeatable differences between animals within breeds were found in cholesterol and phospholipid levels. Estimates of heritability for cholesterol levels from dam-calf regressions were 34± 11 % and 100± 15% at calf ages of 10 and 22 months respectively.In heifers the triglyceride levels in Africander X British and British breeds were significantly higher (P < O· 01) than in the Africander, Brahman, and Brahman X British breeds. Plasma protein. bound iodine was consistently positively associated with cholesterol levels.Within breeds, animals with high plasma cholesterol carried significantly fewer mature cattle ticks (Boophilus microplus).The phospholipid-cholesterol balance for a given cholesterol level was different in males and females.
