Contaminated environments have a large number of bacteria which can accumulate PHA as their energy reserves. Out of 54 isolated bacterial strains from three groups of contaminated sites 48 were found PHA positive. The sites were grouped on the basis of the type of carbon sources i.e. sugars, fatty acids and much diverse type. Strains MFD5, MFD11, UML3, USL2, SEL2, SEL3, SEL10 and PFW1 produced ...

We evaluated the effect of forage quality on response of cattle to supplementation with cooked molasses blocks. In Exp. 1, 175 heifers had ad libitum access to prairie hay (5.2% CP, DM basis). Treatments were a 2 x 3 factorial: supplementation with 0 or 1.96 kg/d of alfalfa DM, and supplementation with no cooked molasses block or with a low-protein or a high-protein cooked molasses block (14.4 ...

The radiation of 14C is very weak 14C+ 14N t PSucrose in first expressed juice and mixed juice was determined by isotope dilution and the results were compared with the conventional pol determination. i t was found that the sucrose content on the average was 0,25% higher using the ID method. Molasses samples, on the contrary, showed a sucrose content which was 0,71% lower than the value found b...
