BIOCHEMICAL STUDIES ON THE RICE BLAST DISEASE (PART 10) BIOCHEMICAL CLASSIFICATION OF PIRICULARIA ORYZAE CAVARA (NO 4)
Abstract
The following results were obtained by cultivating 45 stock-cultures of P.o.c. in the biotine-free base. No 1 and No 2 show a fair degree of propagation, while four other stocks propagate a little and the remaining 39 stocks did not propagate at all. Bioassay results on the biotine quantity in the cultivating solution and in the self-digested substance of washed-bacteria of No 1 and No 2, which were first cultivated in the biotine-free base, revealed a minute degree of biotine formation. The 45 P.o.c. stock-cultures were classified into 11 groups depending upon the extent of sugar and nitrogen consumption and the nitric acid reducibility.
