Application

Application Comment Organism
diagnostics yeast spore-based encapsulation technique is applied to the diagnostic enzyme creatinase. A secretory form of Pseudomonas putida creatinase can be entrapped in the spore wall, and such spores are used as creatinase capsules. The activity of the encapsulated creatinase is largely improved by mild spore wall defective mutations, such as DIT1 or OSW2 deletions. The encapsulated and freeze-dried creatinase is produced without preparing the purified enzyme, and it exhibits resistance to environmental stresses, such as high temperature and SDS treatments. Thus, yeast spores can be applied to establish quick and easy clinical diagnostic methods Pseudomonas putida
