Effect of heat treatment and spray drying on lactobacilli viability and resistance to simulated gastrointestinal digestion
(Elsevier, 2012-10)Commercial probiotic bacteria are delivered mainly as frozen or freeze-dried cultures. However, spray drying is a lower cost technology that could be used for the production of probiotic cultures. In this work we aimed at ... -
Growth of Lactobacillus rhamnosus 64 in whey permeate and study of the effect of mild stresses on survival to spray drying
(2015-09)In this study, we aimed at optimizing the growth of Lactobacillus rhamnosus 64 in whey permeate supplemented with different ingredients and we also studied the effects of mild stresses on the response to heat and oxidative ... -
Impact of native spray-dried lactic acid bacteria, packing density and wilting time on fermentation characteristics of experimental maize and lucerne silages
(Wiley, 2022-03)This study aimed at investigating the effects of an autochthonous microbial inoculant microencapsulated by spray-drying on fermentation parameters, microbiological composition, mycotoxin level and aerobic stability of maize ... -
Spray-dried adjunct cultures of autochthonous non-starter lactic acid bacteria
(2017-08-16)Spray-drying of lactic cultures provides direct-to-vat starters, which facilitate their commercialization and use. However, this process may alter the metabolic activity and deteriorate technological features. In this work, ... -
Spray-drying process preserves the protective capacity of a breast milk-derived Bifidobacterium lactis strain on acute and chronic colitis in mice
(2017-02)Gut microbiota dysbiosis plays a central role in the development and perpetuation of chronic inflammation in inflammatory bowel disease (IBD) and therefore is key target for interventions with high quality and functional ... -
Study of the effects of spray drying in whey‐starch on the probiotic capacity of Lactobacillus rhamnosus 64 in the gut of mice
(2017-10)Aims: To evaluate the effects of spray drying of Lactobacillus rhamnosus 64 on its capacity to modulate the gut immune response and on the attenuation of TNBS‐induced colitis in mice. Methods and Results: Lactobacillus ... -
Study of the effects of spray‐drying on the functionality of probiotic lactobacilli
(2013-05)Three probiotic lactobacilli strains were spray‐dried in 20% (w/v) skim milk and submitted to a simulated gastrointestinal digestion. Fresh or spray‐dried cultures were administered to mice for 5 and 10 days, and Immunoglobulin ... -
Technological variables influencing the growth and stability of a silage inoculant based on spray‐dried lactic acid bacteria
(Wiley, 2020-06)Aims: To investigate the influence of different culture media and fermentation conditions on growth performance and viability of three lactic acid bacteria (LAB) strains with potential as silage inoculants, and to optimize ...
