Abstract:
According to the theory of nucleic acid metabolism, the different select models were designed By means of physical and chemical derived to the production of inosine Bacillus Subtilis JSIM 1019, we have got the mutative strains of auxotroph of different component, the mutative strains lacking of relating enzyme, the mutative strains resisting some metabolic analog in turn Restrain of the production to metabolite has been relieved Two mutative strains of auxotroph xanthine, X 13 and so on were obtained And it also has resistance to 8 azaguanine After the mutative strains had been separated into the single srain respectively, we got X 13 4 the maximum accumulation of adenosine reachs 12 43g/L in substratum cultivated for 72 hours at 36℃
