The growth of irradiated candida utilis in molasses media with and without nitrogen

The growth of irradiated candida utilis in molassea media with and without nitrogen. The experiment has been done to compare the growth of C.utilis on molasses media containing nitrogen and without nitrogen. The C.utilis irradiated with gamma rays from 60Co (Gamma Cell 220) with different exposure i.e. 0,21, 43, 64, 85 and 106 Gy and then inoculated on 2% molasses medium with and without N, and incubated at 280 +- 20C for 0 and 1 day. Parameters observed were the number of colony, the size of colony growth on 2% molasses medium with and without N. The results showed that the growth in media molasses with N was different from that without N. The incubation effect seemed to be a significant, while the effect of irradiation was not significant, which was probably due to the insufficient dose used for inducing stimulation. The interaction between the added Nand incubation was also significant. 13 refs
