• Yintoni iStreptococcus Thermophilus ?
Kwimbali ende yokufuywa kwabantu kwi-microorganisms, iStreptococcus thermophilus iye yaba luhlobo lwembombo yeshishini lobisi kunye nokumelana nobushushu obukhethekileyo kunye nomthamo we-metabolic. Kwi-2025, iziphumo zophando zamva nje ze-Chinese Academy of Food Fermentation Industries kunye ne-International Dairy Federation (IDF) ziqinisekisile imeko yayo yeentlobo ezizimeleyo kwinqanaba le-genome okokuqala, ukuphawula isiteji esitsha ekuqondeni kwesayensi yale "golide yolwelo". Njengondoqo weemveliso zobisi ezivundisiweyo ezinemveliso yonyaka engaphezulu kwezigidi ezingama-30 zeetoni kwihlabathi liphela, iStreptococcus thermophilus igqobhoza imida yemveli kwaye ibeka amaza okutsha ekutyeni okusebenzayo, impilo yezonyango kunye neminye imimandla.
I-Streptococcus thermophilus yathiywa okokuqala ngu-Orla-Jensen kwi-1919. Emva kwengxabano ye-subspecies ehlayo kwi-1984 kunye nokubuyiselwa kweentlobo kwi-1991, ekugqibeleni yamisela imeko yayo yeentlobo ezizimeleyo ngokulandelelana kwe-genome (ANI ≥ 96.5%, dD070 ye-US, i-US 275 ≥ i-US , i-US 275 ≥ i-Union yase-US, i-US 275 ≥ i-US ≥ i-US ≥ 270 ≥ . I-FDA kunye ne-IDF zonke ziyidwelise njengohlobo lokutya olukhuselekileyo (GRAS). Kwi-2025, ushicilelo lwesihlanu lwe-IDF "Uluhlu lweeBhaktheriya zokuTya okuFermented" luya kugqiba ukuhlaziywa okusemgangathweni.
I-Streptococcus thermophilus i-Gram-positive, i-non-spore-forming, i-facultative anaerobic, kunye neqondo lokushisa eliphezulu lokukhula kwe-45-50 ° C, uluhlu lokunyamezela kwe-pH ye-3.5-8.5, kunye nokumelana nokushisa okunamandla (izinga lokusinda> 80% emva kwe-85 ° C unyango lwemizuzu engama-30).
• Ziziphi iiNzuzoStreptococcus Thermophilus?
Ngokusekwe kwizifundo ezingaphezu kwama-2,000 kwihlabathi liphela, iStreptococcus thermophilus ibonisa ixabiso lezempilo elinemilinganiselo emininzi:
1. Ulawulo lweMpilo yamathumbu
Ukulawulwa kwezityalo zebhaktheriya: Ukuthintela ibhaktheriya ye-pathogenic ngokukhupha i-bacteriocins (efana ne-Salivaricin), ukwandisa ubuninzi be-intestinal bifidobacteria ngamaxesha angama-2-3.
Ukulungiswa kwe-Mucosal: Phakamisa ukubonakaliswa kwe-Gal3ST2 gene, ukunciphisa i-fucosylation ye-colon mucin, kunye nokunciphisa i-chemotherapy-induced intestinal mucosal inflammation.
2. Ukulawulwa kweMetabolic
Ukulawula iswekile yegazi: Ukungenelela kwebhaktheriya ebulawa ukushisa kunokunciphisa iswekile yegazi ngokukhawuleza kwiigundane zesifo sikashukela nge-23% kunye nokuphucula ukuvakalelwa kwe-insulin (i-HOMA-IR index yehle nge-41%).
I-cholesterol metabolism:Streptococcus thermophilusinqanda umsebenzi we-HMG-CoA we-reductase, ukunciphisa i-serum LDL-C nge-8.4%, kunye nokunyusa amanqanaba e-HDL-C.
3. Ukwandiswa koKhuseleko
Ukulawulwa kwe-Cytokine: Ukuvuselela i-IL-10 secretion (ukugxininiswa kwandiswe ngamaxesha e-1.8), inqanda i-TNF-α (iyancipha nge-52%), kwaye ikhulule ukuvuvukala okungapheliyo.
Ukuqiniswa komqobo we-mucosal: Ukukhuthaza ukubonakaliswa kweeprotheni ezidibeneyo (ZO-1, i-Occludin) kunye nokunciphisa ukunyanzeliswa kwamathumbu emathunjini (FITC-dextran permeability yehle nge-37%).
.
4. Amandla okuchasa umhlaza
Ukuthintela umhlaza we-colorectal: Ukunciphisa i-carcinogens ngendlela ye-β-galactosidase, ukunciphisa iziganeko ze-tumor kwi-Apcmin / + iigundane nge-58%.
I-Apoptosis induction: Yenza indlela yeCaspase-3 isebenze, ibangela ukunyuka kwe-4.3-fold in the apoptosis rate of HT-29 colon cancer cells.
• Yintoni UkusetyenziswaStreptococcus Thermophilus?
I-Streptococcus thermophilus yaphula imida yemveli kwaye yenza i-matrix yesicelo esahlukileyo:
1. Ishishini lobisi
I-yoghurt / i-cheese: idityaniswe ne-Lactobacillus bulgaricus, inciphisa ixesha lokudibanisa kwiiyure ze-4 kunye nokwandisa imveliso yemveliso nge-15%.
Iimveliso ezinoshukela ophantsi / ophantsi: Ngeteknoloji ye-EPS ye-synthesis, ubunzima be-fat-fat cheese bunyuswa ngamaxesha e-2 ukulinganisa ukuthungwa kwe-fat-fat.
2. Ukutya okuSebenzayo
Ukutya okulawulwa ngoshukela: ukutya okuziinkozo kunye ne-5% ye-powder yebhaktheriya kunokulibazisa i-postprandial i-sugar peak ngeeyure ze-1.5.
Immunoenhancer:Streptococcus thermophilusidityaniswe ne-oligofructose, izinga losulelo lwendlela yokuphefumla ebantwaneni lehle ngama-33%.
3. Impilo yezoNyango
Ukutya okukhethekileyo kwezonyango: kusetyenziselwa ukulungiswa kwesondlo sokungena ekuphuculeni imeko yesondlo sezigulane ze-chemotherapy (i-albumin inyuke nge-1.2 g / dL).
Amachiza eProbiotic: adityaniswe ne-bifidobacteria ukuphuhlisa iipilisi zonyango ze-IBS, kunye nezinga lokunciphisa ukudumba kwe-78%.
.
4. ULimo kunye noKhuseleko lokusiNgqongileyo
Izongezo zesondlo: Nciphisa izinga lorhudo lwamantshontsho ehagu ngama-42% kwaye lonyuse izinga lokuguqulwa kwesondlo nge-11%.
Ukucocwa kwamanzi amdaka: Yehlisa umgangatho we-COD wamanzi amdaka obisi ngama-65% kwaye unciphise ukuveliswa kodaka ngama-30%.
