A Taxonomic Study on the Koji Molds

Part 1. Genetic Segregations in Aspergillus tamarii-oryzae Group demonstrated through Single-Sporee Cultures

Abstract

Investigtions were made on the genetic purity, of twenty one species or subspecies in A. ta-marii-oryzae group through successive series of monoconidial cultures.
According to the identification of the seventeen homogenic strains obtained by repeated twenty single-spore isolations, A. tainurii and A. sojae should be included in A. tamarii-oryzae group in addition to the, five species of A. flavus-oryzae group T_HOM et R_APER.
