nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. analyses included total nitrogen (tn), non-casein nitrogen (ncn), non-proteinnitrogen (npn), casein nitrogen (cn) and proteolysis index (pi). yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°c. tn, cn and pi contentsof yoghurt milk samples with high somatic cell sc...

A study was made of variation in weight of the host lymph nodes, spleen, and thymus, after implantation of transplantable tumors in susceptible and See PDF for Structure non-susceptible hosts. The lymph nodes and spleens of non-susceptible hosts increased in weight during the period when the organs were participating in the immunological response, though an increase also took place in susceptib...

The aim of this study was to determine the correlations between output parameters in sacco method and CNCPS (Cornell Net Carbohydrate Protein System). Both methods were tested on 106 samples from feeds classified into following categories: extracted meal cakes, cereals, legumes, maize alfalfa silage, other silages, DDGS (dried distiller’s grains with solubles), oilseeds various hays. effective ...

Quality changes of protein and non-protein nitrogen compounds during industrial fishmeal processing fatty pelagic species (mackerel/herring rest material blend, MHB) lean fish (whole blue whiting, BW) were studied to identify steps that require optimization allow production products for human consumption. Samples from protein-rich streams throughout the analyzed proximate composition, salt solu...

Cheese ripening causes intense proteolysis, particularly when the cheese contains starter cultures. Several studies have shown presence of bioactive peptides in goat’s milk cheeses with antioxidant activity. Mexican goat cheeses’ peptide fractions were evaluated at different stages. Additionally, they correlated their Proteolysis was measured acid-soluble nitrogen and non-protein using reverse-...

the main objective of this study was to investigate the effect of enterococci isolated from traditional lighvan cheese on the quality of iranian uf white during ripening. four samples of cheese were provided from four different cheese production units in lighvan region. strains of enterococci in these samples were isolated by standard microbiological methods and selective medium of kanamycin es...

the aim of this study was to investigate the effects of starters and storage temperature (4 ºc, 25 ºc) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.kefirs produced by kfa and chr. hansen starters were stored at 4 ºc and 25 ºc for 40 days. ph andacidity at 4 ºc did not change (p ≥ 0.05), while at 25 ºc ph and total solid decreased as well a...

Cells of the non-diazotrophic cyanobacterium Synechococcus sp. strain PCC 7942 acclimate to nitrogen deprivation by differentiating into non-pigmented resting cells, which are able to survive prolonged periods of starvation. In this study, the physiological properties of the long-term nitrogen-starved cells are investigated in an attempt to elucidate the mechanisms of maintenance of viability. ...
