Determination of Adsorption Isotherm for L-Lysine Imprinted Polymer
The optimization of adsorption-based operations requires an accurate model to represent the separation process. In the present study, single-component adsorption data of L-lysine on its imprinted polymer were fitted to Freundlich, Langmuir-type and Jovanovic-type models. L-Lysine imprinted polymer (LLIP) was prepared by free radical solution polymerization. The best estimate of the parameters o...
متن کاملBioefficacy of Lysine from L-lysine Sulfate and L-lysine⋅HCl for 10 to 20 kg Pigs
The objective of this study was to compare the bioefficacy of L-lysine sulfate relative to L-lysine⋅HCl for 10 to 20 kg pigs. Two experiments were conducted to determine the bioefficacy of the two sources of lysine using daily gain, feed conversion, plasma urea nitrogen and nitrogen retention as the response criteria. In experiment 1, 168 crossbred barrows (Landrace×Large White), weaned at 28±3...
متن کاملBioefficacy of L-lysine sulfate compared with feed-grade L-lysine-HCl in young pigs.
A pig growth assay was conducted to determine the relative biological value (RBV) of lysine from L-lysine sulfate compared with feed-grade L-lysine HCl. One hundred nursery pigs with an average initial BW of 9.5 +/- 1.5 kg were blocked by BW and gender and allotted randomly to five dietary treatments in five replicates of four pigs per pen. A corn-peanut meal diet containing 0.6% total lysine (...
متن کاملInteraction of Poly-l-lysine with Chromatin
The priming capacity of chromatin of fixed nuclei and chromosomes for exogenous DNA polymerase can be evaluated radioautographically by the incorporation of labeled nucleotides. It had previously been reported that acid fixation or acid treatment of alcohol-fixed tissues led to increased priming when calf thymus DNA polymerases, specific for single-stranded DNA, were used. We employed Escherich...
متن کاملEnzymatic production of 5-aminovalerate from l-lysine using l-lysine monooxygenase and 5-aminovaleramide amidohydrolase
5-Aminovalerate is a potential C5 platform chemical for synthesis of valerolactam, 5-hydroxyvalerate, glutarate, and 1,5-pentanediol. It is a metabolite of l-lysine catabolism through the aminovalerate pathway in Pseudomonas putida. L-Lysine monooxygenase (DavB) and 5-aminovaleramide amidohydrolase (DavA) play key roles in the biotransformation of L-lysine into 5-aminovalerate. Here, DavB and D...
