Effects of plasticizer types and whey protein concentrate (WPC) as coatings were evaluated on internal quality shelf life eggs stored for 42 days. Eggs coated with WPC at 8 % solution combined the plasticizers glycerol (GLY), sorbitol (SOR), propylene glycol (PRO). The 20 °C. Weight loss, Haugh Unit (HU), albumen yolk pH, index (YI) weekly from day 0 to After, electron microscopy eggshell struc...

This study reports that common carp (Cyprinus carpio) embryos were successfully frozen and preserved by vitrification. The modified Haga solution was tested by using two different cryoprotectants and three different concentrations at 4°C to obtain appropriate vitrified solutions ((dimethylsulfoxide 5, 10, 15% (DMSO) and glycerol 5, 10, 15% (gly)) in the study.  The hatching rates of embryos exp...

We examined the effect of growth conditions in chemostat culture on the quantity and composition of the cell wall teichoic acids of Streptococcus mutans BHT and Lactobacillus plantarum NCIB 7220 and the membrane lipoteichoic acid from S. mutans Ingbritt. With the cell wall teichoic acids, which are covalently linked to peptidoglycan, the amount of teichoic acid is independent of the growth cond...

The 4-day response of C3H/HeJ mice to sheep erythrocytes was suppressed by a lipid-free teichoic acid with an average molecular weight of 2,900 when it was administered by the intraperitoneal route. Enhancement was not observed at that time, and neither suppression nor enhancement could be demonstrated by the intravenous route. Either suppression or enhancement of background plaques could be in...

Although exponential growth of Bacillus subtilis 168 in a phosphate-limited medium halted with the exhaustion of inorganic phosphate, the bacteria continued to grow at a slower rate for a further 3 to 4 h at 37 degrees C. This postexponential growth in the absence of an exogenous phosphate supply was accompanied by a loss of teichoic acid from the cell walls of the bacteria. Quantitative analys...
