Effect of zymomonas mobilis probiotic on cholesterol and its lipoprotein fractions and the intestinal regulation.

Zymomonas mobilis have characteristics that classify it as probiotic. Thus, this study aimed to evaluate the effect of regular consumption of fermented broth of this strain on the intestinal function of individuals with changes in intestinal transit. This is a randomized, descriptive and quantitative clinical trial, a sample composed of undergraduate students from a university center in Caruaru. After screening for individuals with constipation according to the inclusion and exclusion criteria, only 13 agreed to participate in the study. They were divided into groups: group 1 received Zymomonas mobilis fermented broth once a day; group 2 also received the fermented broth in the same concentration cells being twice a day; group 3 received cell-free fermented broth once daily; and group 4, placebo, received saline once daily, all groups drank for fifteen days, and laboratory tests were performed to check lipid profile before and after that period. Observed an increase in evacuation days in all groups averaged in media 7.0-10.5 days. Groups 1 and 2 showed an increase in total cholesterol (0.5% and 5.0%, respectively), HDL cholesterol (4.1% and 24.1%), LDL cholesterol (4.9% and 8.4%), VLDL cholesterol (17.9% and 11.2%) and triglycerides (19.1% and 27.9%). In group 3, there was a reduction of total cholesterol (-2.4%), LDL cholesterol (-11.2%), VLDL cholesterol (-15.9%), triglycerides (-27.7%) and increase in HDL cholesterol (25.7%). Thus, the broth fermented with Zymomonas mobilis regulated the intestinal transit, but did not improve the lipid profile, while the without cells broth showed a better lipid profile.
