Abstract
2.5'ten az olan bir asilasyon maddesi/beta-laktam çekirdegi mol oranindaki bir asilasyon maddesi yarimiyla, bir beta-laktam çekirdeginin bir enzim asilasyon tepkimesine maruz birakildigi, bir beta-laktam antibiyotigi hazirlanmasi için bir islemdir, ki burada asilasyon maddesinin ve/veya beta-laktam çekirdeginin tepkime karisiminda asilasyon tepkimesinin en azindan bir kisminda süper-doymus durumdadir. Islemde, asilasyon tepkimesinin gerçeklestirildigi pH veya sicakliktan farkli bir pH veya daha yüksek sicakliktaki örnegin bir beta-laktam çekirdegi ve/veya asilasyon maddesi konsantre bulamaci veya çözeltisi tepkime karisimina eklenir. Tepkime karisiminda hem beta-laktam çekirdegi hem de asilasyon maddesi süper-doymus olabilir.
