Speciile De Bacterii Lactice Şi Nivelul Colesterolului (Lactic Acid Bacteria Species and Cholesterol Level)

Abstract

Romanian Abstract: Bolile cardiovasculare reprezintă principala cauză a mortalităţii în Europa de Vest şi ele sunt asociate cu o creştere a valorii colesterolului sanguin. Organismul uman nu are echipamentul enzimatic necesar pentru degradarea totală a compuşilor steroizi. Speciile de bacterii lactice Lactobacillus şi Bifidobacterium au capacitatea de a metaboliza colesterolul. Efectul hipocolesterolemiant al probioticelor poate fi atribuit abilităţii tulpinilor de bacterii lactice de a lega colesterolul la nivel intestinal. Marea majoritate a produselor probiotice conţin bacterii lactice, microorganisme considerate benefice pentru organismele gazdă. Utilizarea probioticelor poate reprezenta o alternativă suplimentară pentru creşterea şi menţinerea stării de sănătate a organismului uman.

English Abstract: Cardiovascular diseases represent the main cause of mortality in WestEuropean countries and they are associated with increased values of blood cholesterol. The human body does not contain the enzymatic equipment necessary for the total degradation of this steroid compound. Lactic bacteria species Lactobacillus and Bifidobacterium have the capacity of metabolising cholesterol. The hypocholesteremiant effect of the probiotics can be attributed to the ability of the strains of lactic bacteria of connecting cholesterol at the intestinal level. Most of probiotic products are containing lactic acid bacteria, microorganisms considered as commensal and harmless for the host organisms. The use of probiotics can represent a supplementary alternative for increasing and maintaining the health of the human body.
