Their health benefits and physicochemical properties have been the subject of extensive research. The HoPS functional properties are determined by molecular weight, the type of glycosidic link ages, degrees of branching and chemical composition. The dextransucrases (DSases) produce a kind of HoPS (dextrans), ... -
Development and application of a quantitative real-time PCR assay for rapid detection of the multifaceted yeast Kazachstania servazzii in food.
avril 2017, CARAHArticle scientifiqueThe beneficial contributions of Kazachstania servazzii are well-established in various food processes. This yeast also contributes in the spoilage of finished packaged food due to abundant gas production. In particular, an occurrence of K. servazzii was recently positively correlated with the formation of severe package swelling of some prepared fresh pizzas. To circumscribe this concern, a quantitative ... -
Development of a standardized multiplex SSR kit for genotyping both goats and sheep
03 novembre 2021, HE CondorcetCARAHArticle scientifique"In this technical note, we report the development of a reliable standardized protocol based on the multiplex SSRPCR approach for genotyping the two small ruminant species, goats and sheep. The method is based on PCR conditions optimization allowing 12 informative microsatellites (SSR) markers to be co-amplified in two multiplex sets of 6 SSR markers, followed by a co-migration into one run onto a ... -
