Antibacterial antibiotics, compound A and B, were isolated from sclerotia of R. solani AG-6 and identified them spectroscopically as the same pyron compounds as those from sclerotia of R. tuliparum. Of which, a compound inhibited the growth of many bacteria, but the other had no effect either on the fungi or on the bacteria. Sclerotia of seven anastomosis groups of R. solani (AG-1, AG-2, AG-3, AG-4, AG-5, AG-6 and AG-BI) were checked the ability to produce compounds by TLC and GLC. Antibacterial antibiotic compounds were detected in sclerotia of all isolates of AG-6, but not of other anastomosis groups of R. solani so far tested. From these results, it was found that there might be group specificity in the production of antibiotic pyron compounds among anastomosis groups of R. solani.
