A plate method for rapid screening of Ketogulonicigenium vulgare mutants for enhanced 2-keto-l-gulonic acid production

Braz. j. microbiol; 48 (3), 2017
Abstract A new plate method was developed for rapid screening of Ketogulonicigenium vulgare mutants overproducing 2-keto-l-gulonic acid (2-KLG). The screening methodology took the advantage of the acidity caused by 2-KLG, which changes the color of bromothymol blue (pH indicator) from blue to yellow. Usi...

Radiochemical quality control of kits labelled with Tc-99m produced at IPEN-CNEN/SP

Os radiofármacos marcados com 99mTc säo rotineiramente usados nos laboratórios de Medicina Nuclear. A maioria destes produtos utilizam Sn++ para reduzir o Tc(VII) a um estado de valência menor, facilitando a formaçäo de complexos na reaçäo. O sistema de cromatografia miniaturizada, realizado nos ...
