 ===Usage and Biology===
+Creatinine is a urinary human waste, rich in carbon and nitrogen. During recent years countless research has been done on the topic of waste-upcycling and revalorization. Creatinine is one of the few human waste products still to be valorized during space missions. In our project, we wanted to use it as carbon and nitrogen source to support the growth of Pseudomonas fluorecens, which serves as biostimulant for plant.  Certain species of Pseudomonas, such as Pseudomonas putida can degrade creatinine and use it as carbon and nitrogen sources to ensure its growth. There is no bibliography on this pathway being present in P.fluorescens. The two enzymes permitting creatinine metabolization are creatinine amidohydrolase (CrnA, EC 3.5.2.10) and creatinase (CreA, EC 3.5.3.3), both expressed in the same operon. The first catalyzes the hydrolysis of creatinine into creatine. Then, the creatinase catalyzes the hydrolysis of creatine into sarcosine and urea. Finally, in P. putida, sarcosine is degraded by a sarcosine oxidase to join the glycine metabolism (Figure 1).
