Abstract

It has been shown that the molds Aspergillus niger, Aspergillus clavatus, Trichoderma ligorum, Rhizopus nigricans, and Penicillium roqueforti are capable of producing a substance or substances stimulating yeast growth;It has been shown that this material of a Bios nature is produced from both glycerine and sucrose substrates;The Bios producing properties of Aspergillus niger have been studied with respect to time, the composition of the media, production of acids, and of mycelium;A study of the nature of the stimulant has been made;It has been shown that the Bios produced by mold is apparently not the same as Miller's Bios fractions;A synthetic medium has been devised which gives high yields of acid and mycelium with Aspergillus niger.
