Yeruusaalem, 27 Jannaayo, 2026 (TPS-IL) — Cilmibaadhis cusub oo ay sameeyeen khubaro ka tirsan Jaamacadda Cibraaniga ee Yeruusaalem ayaa waxay soo saareen dareeme nool oo iftiimaya marka uu ogaado khamriga uu xumaaday. Dareemahan, oo laga sameeyay bakteeriya la beddelay, ayaa iftiimaya marka uu ogaado asiidha acetic, oo ah kiimiko keenta dhadhan qadhaadh oo la mid ah khal, taasoo siinaysa samaynta khamriga digniin hore ka hor inta aanay khamrigu xumaan ama dhadhanku burburin.
Cilmi-baaristan waxaa hoggaaminayay ardayda PhD-ga Yulia Melnik-Kesler, iyadoo uu caawinayo Prof. Yael Helman, iyo Prof. Oded Shoseyov. Daraasaddooda, oo lagu daabacay joornaalka Microbial Biotechnology, ayaa muujinaysa hab ka fudud oo ka jaban kii hore ee lagu tijaabin jiray shaybaadhka, kaasoo ku tiirsan chromatography-ga gaaska iyo dareeraha, isla markaana noqon kara mid qaali ah oo dhib badan.
"Khamriga xumaada waxaa inta badan sababa asiidha acetic, taasoo aan kaliya keenin dhadhan xun, balse sidoo kale joojin karta habka khamriga loo sameeyo, taasoo khamriga ka dhigaysa mid aan la cabbi karin," ayuu yiri Prof. Helman. "Nidaamkan wuxuu noo ogolaanayaa inaan ogaano asiidha acetic waqtiga dhabta ah, iyada oo aan loo baahnayn qalab qaali ah ama habraac adag. Waxay furaysaa albaabka la socodka tayada habka khamriga loo sameeyo, waxaana laga yaabaa mustaqbalka inuu taageero baaritaanka caafimaad ee ku salaysan calaamadeeyayaal gaas ah."
Dareemaha nool wuxuu ka shaqeeyaa iyadoo la isticmaalayo nidaamka bakteeriyada ee YwbIR, oo asal ahaan laga helay Bacillus subtilis. Marka la ogaado asiidha acetic, nidaamku wuxuu kiciyaa hiddo-side iftiin soo saara, taasoo keenta in bakteeriyadu iftiimiso. Tijaabooyinka shaybaadhka, dareemuhu wuxuu muujiyay jawaab xooggan oo toos ah oo ku aaddan xaddiga asiidha acetic ee u dhaxaysa 0 ilaa 1 garaam halkii litir – taasoo muhiim u ah samaynta khamriga, maadaama xumaantu ay caadi ahaan bilawdo qiyaastii 0.7 garaam halkii litir. Xilliyada xumaanta, iftiinka dareemaha ayaa kordhay shan ilaa siddeed jeer, taasoo bixisay digniin hore ka hor inta khamrigu uusan noqon mid aan la cabbi karin.
Mid ka mid ah hal-abuurka muhiimka ah waa awoodda dareemaha ee lagu ogaan karo asiidha acetic ma aha oo kaliya khamriga dareeraha ah, laakiin sidoo kale hawada korkiisa. Tani waxay u oggolaanaysaa samaynta khamriga inay la socdaan hawo-mareenka weelasha khamriga lagu keydiyo iyagoo aan furin, taasoo yaraynaysa khatarta wasakhaynta. Tijaabooyinka khamriga cas iyo kan cad ee ganacsiga ayaa muujiyay in dareemaha nool uu si fudud u kala saari karo khamriga caadiga ah iyo kuwa si macmal ah loo xumeeyay oo lagu daray asiidha acetic, isagoo soo saaray koror cad oo iftiin ah laba saacadood gudahood.
Nidaamku wuxuu sidoo kale sii ahaadaa mid la isku halayn karo deegaannada ay ku badan tahay khamriga, isagoo si sax ah uga shaqeynaya khamriga leh aalkolo dhan ilaa 14.5 boqolkiiba, heer kaasoo caadi ahaan carqaladeeya hababka baaritaanka caadiga ah.
Marka laga soo tago samaynta khamriga, cilmi-baarayaashu waxay arkaan codsiyo ballaaran oo dareemaha ah oo ku saabsan warshadaha ku salaysan khamiirka, baaritaanka caafimaad, iyo cilmi-baarista shaybaadhka.
Waxay ka caawin kartaa ka hortagga xumaanta iyo hagaajinta wax-soo-saarka cuntada sida khal, kombucha, iyo suugada soy, iyo sidoo kale hababka khamiirka ee bio-fuel. Noocyada mustaqbalka ayaa sidoo kale loo habayn karaa si loo ogaado calaamadeeyayaal gaas ah oo ku jira neef-qaadashada.
"Habkan wuxuu xoojin karaa tayada wax-soo-saarka warshado badan isagoo yaraynaya kharashka iyo baahida loo qabo qalab shaybaadh oo adag," ayay tiri Melnik-Kesler. "Waa tallaabo horumarineed oo xiiso leh oo loogu talagalay sayniska cuntada iyo caafimaadka aadanaha.
