Powder quality and probiotic viability after spray drying and subsequent storage were measured. Spray drying probiotics in reconstituted goat's milk resulted in a significant reduction in the viability of all three probiotics. However, all three probiotics were able to maintain satisfactory viability levels (10⁶-10⁸cfu/g) after spray drying. While storage temperature did not appear to have a significant effect on moisture content, the viability of all three strains declined dramatically when stored at 30°C but lactobacilli and propionibacteria remained virtually unaffected under storage at 4°C, satisfying recommendations regarding the level of viable cells in probiotic foods.]]> Sat 24 Mar 2018 07:25:49 AEDT ]]> Dairy propionibacteria as direct-fed microbials: in vitro effect on acid metabolism of Streptococcus bovis and Megasphaera elsdenii https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47504 Megasphaera elsdenii and Streptococcus bovis in various co-culture combinations in a simulated rumen environment comprising unmodified rumen digesta supplemented with excess glucose. While suppression of lactic acid accumulation by both the dairy propionibacteria and M. elsdenii in the presence of S. bovis in the simulated rumen conditions was evident, propionibacteria were found to be more effective than M. elsdenii in controlling lactic acid levels.]]> Mon 23 Jan 2023 12:08:28 AEDT ]]>
