The Germinative Power of the Conidia of Aspergillus 



ORYZiE. 

 Mary F. Hiller. 



Former investigations of the mould, Aspergillus oryzae, liave resulted 

 in many practical suggestions which have determined this mould to be 

 of interest to the commercial as well as to the scientific public. 



In 1876 Ahlburg, the first investigator of the mould, described the 

 fungus and named it EiU'otium oryzae. Cohn. in 1883, in his study of 

 moulds as industrial factors, called it Aspergillus oryzae. Biisgen, in 1883, 

 gave the first complete description of this mould, and in 1893 Welimer 

 attempted a structural study. From this time many investigators were 

 at work in many different lal)oratories working out the life histoiy of the 

 fungus. It was Takamiue, a Japanese chemist, who introduced Asper- 

 gillus oryzae into the laboratories of this counti-y. 



The careful experiments of many investigators, among whom are Jor- 

 gensen. Hansen, Klocher, also Atkinson and Hoffman, who have treated 

 it from the industrial standpoint, have resulted in suggesting for this 

 mould many interesting properties, such as the claims that 'the mycelium.
