Species and Varieties in the<i>Rhizopus Arrhizus-Rhizopus Oryzae</i>Group as Indicated by Their DNA Complementarity

Abstract

DNA renaturation experiments gave evidence to conclude that Rhizopus arrhizus, R. oryzae, R. delemar, Amylomyces rouxii, R. delemar var. minimus, R. delemar var. multiplicisporus, R. arrhizus var. delemar, R. chungkuoensis var. isofermentarius, and R. javanicus var. kawasakiensis can be accommodated in three taxa, namely, R. arrhizus var. arrhizus, R. arrhizus var. rouxii, and R. arrhizus var. delemar.
