Turkish Journal of Veterinary & Animal Sciences

Polysaccharide-degrading enzymes of the anaerobic rumen bacterium Ruminococcus flavefaciens strain 17 were exmined. This work demonstrated that R. flavefaciens strain 17 produces a complex array of enzymes active against cellulose, hemicellulose (xylan) and lignin. These enzymes are xylanase, avicellase, acid-swollen cellulase, carboxymethyl cellulase (CMCase), pNP-cellobiosidase (pNPC), pNP-glucopyranosidase (pNPG), pNP-xylopyranosidase (pNPX) and pNP-arabinofuranosidase (pNPA). Although R. flavefaciens is an anaerobic bacterium, its enzymes worked optimally under aerobic conditions and with dithiothreitol (DTT), except in the case of pNP-xylopyranosidase. pNP-xylopyranosidase exhibited a higher level of activity under anaerobic conditions with DTT. It was demonstrated that the cross-links between arabinose side chains, which …

Blood Serum Concentrations Of Selenium And Glutathione Peroxidase Activity In Akkaraman Sheep, Taner Pamukçu, Tevhi̇de Sel, Gül Yarim

Turkish Journal of Veterinary & Animal Sciences

Selenium and other essential elements play an important role in animal husbandry. These elements help to minimize infectious diseases, reduce concomitant stresses and bring about optimal productive and reproductive performance. The mean serum selenium concentration of the sheep sampled in this study was 303.65 ng/ml. Such values are considered to be indicative of adequate dietary supplementation. Serum glutathione peroxidase activity in the sheep sampled in this study was also analysed, and the mean glutathione peroxidase activity was 3.65 nmolNADPH+H+/min/mg protein. It is recommended that producers monitor the selenium in serum in order to maintain adequate nutrition and performance in sheep.

Photoinactivation Of Buffalo Liver And Kidney Tissue Arginases And Its Kinetic Properties, Necmi̇ Özdemi̇r, Mehtap Özçeli̇k

Turkish Journal of Veterinary & Animal Sciences

Exposure of buffalo liver and kidney tissue arginases to a 150 w light source from a distance of 8-10 cm, in the presence of 0.05mM methylene blue, caused significant inhibition of arginase activity. It was determined that this inhibition occurred differently in liver and kidney tissues. Arginase activity was spectrophotometrically measured using the Thiosemicarbazide diacetyl-monoxime urea (TDMU) method. Following preincubation with MnCl_2, exposure to a 150 w light source and the addition of methylene blue, the activity of arginase was found to be lower than that after preincubation with a 150 w light source and methylene blue and the addition …
