| Summary: | <strong><strong><em></em></strong></strong><p align="left"><strong>Background <span style="font-size: xx-small; font-family: Times New Roman;"><strong><span style="font-size: xx-small; font-family: Times New Roman;">: </span></strong></span></strong><span style="font-size: xx-small; font-family: Times New Roman;"><span style="font-size: xx-small; font-family: Times New Roman;">Kefir contains lactic acid bacteria (</span></span><em><span style="font-size: xx-small; font-family: Times New Roman;">Lactobacillus, Lactococcus, Leuconostoc, </span></em>Acetobacter and Streptococcus<span style="font-size: xx-small; font-family: Times New Roman;"><span style="font-size: xx-small; font-family: Times New Roman;">) and yeasts (</span></span><em><span style="font-size: xx-small; font-family: Times New Roman;">Kluyveromyces, Torula, Candida, Saccharomyces ).</span></em>Kefiran is the polysaccharide produced by lactic acid bacteria in kefir.</p><p align="left"><strong>Methods</strong> <span style="font-size: xx-small; font-family: Times New Roman;">: Kefiran was prepared from milk containing 0.5% fat and 10 grams kefir grains and </span>was separated from kefir by ethanol (0.02 gram) following entrapping the platelets to this polymer. Ligand of the platelet-polysaccharide was studied by FTIR.</p><p align="left"><strong>Results <span style="font-size: xx-small; font-family: Times New Roman;"><strong><span style="font-size: xx-small; font-family: Times New Roman;">: </span></strong></span></strong><span style="font-size: xx-small; font-family: Times New Roman;">FTIR results showed that the bands of C-O and C-O-C connections were formed and </span>the polysaccharides had been attached to the receptors of the platelet glycoproteins (GP Ib,GPIIb / IIIa). Stability and encapsulation of the platelet and kefiran were assessed by Coulter Counter. Encapsulation of the platelets by polysaccharide at the beginning caused to reduce the number of platelets following by releasing of 50% of the platelets after 3 hours.</p><p align="left"><strong>Conclusion <span style="font-size: xx-small; font-family: Times New Roman;"><strong><span style="font-size: xx-small; font-family: Times New Roman;">: </span></strong></span></strong><span style="font-size: xx-small; font-family: Times New Roman;">The platelets were encapsulated in kefiran polymer and detected for bioavailability </span>as new drug for surface bleeding. Also, kefiran has antimicrobial and antifungal properties. On the other hand, the existence of nisin in kefiran could be useful as an antibacterial lantibiotic.</p><p align="left"> </p> |
