Abstract

Konzumacijom probiotičkih sojeva Lactobacillus plantarum D13 i Bifidobacterium animalis subs. lactis Bb12 promovira se ljudsko zdravlje i oplemenjuje se crijevna mikroflora. Probiotici se uobičajeno konzumiraju kao dodaci prehrani, ali u ovom istraživanju će se ispitivati preživljavanje probiotičkih sojeva u guar gelu za rektalnu primjenu. Guar gel služi kao nosač bakterijskih stanica te je provedena analiza gelova različitih koncentracija guara kako bi se odredila optimalna koncentracija. Probiotički sojevi čuvaju se na 4 °C te nakon 10 i 30 dana mjeri se broj vijabilnih stanica.

Abstract (english)

Lactobacillus plantarum D13 and Bifidobacterium animalis subs. lactis Bb12 are probiotic bacteria that promote health and enrich the colonic microbiome. Probiotics are usually consumed through food supplements but this analysis will test survivability of probiotic strains in guar gum for rectal application. Guar gum is used as a matrix for probiotics and to determine the optimal concentration of guar this analysis will include testing gels with different concentrations of guar gum. Probiotic strains are kept on 4 °C and after 10 and 30 days number of viable cells is measured using plate counting method.
