Abstract
Pen. islandicum was artificially cultured on polished rice by the authors. The yellowsis rice thus prepared was used for the feeding tests on experimental animals.
The process of yellowsis rice preparation was the same as that for Koji, and three steps of incubation time, two, four, and seven days, was chosen, at temperature 33°C, and resulting yellowsis rice was dried and groud to flour.
Feeding tests were performed triplicatedly and test diets Containing the above described rice at 80% level were administered on mice for 45 and 60 days.
Though it is difficult to extract some conclusion from these results, weak toxicity can be generally recognized in the yellowsis rice, but those fed the yellowsis rice for 2 days showed no toxicity and showed the same growth as those fed with control normal rice diet.
